Water ChemistryYour Swimming Pools CapacityHow many gallons of water does your swimming pool hold? This can be a very easy or a very toughquestion depending on your point of view. It is without a doubt, though, an extremely important question.It is nearly impossible to add proper dosages of chemicals to your pool if you do not know its capacity.A small inground pool may hold around 7,500 gallons of water while a large one may hold more than40,000 gallons. A proper dosage in one pool will definitely not be a proper dosage in the other. For yourconvenience, a gallonage chart for Imperial Pools is given below.

By knowing your pool’s capacity, you will have one half of the information that you need to properly addchemicals to the pool.

Testing Your Pool WaterWhile your pool’s capacity is extremely important to know, it is alsoimportant to know what the chemical levels are in the pool. Proper chemicallevels in the pool helps ensure that the water is invitingly clear, clean, andhealthy. When the chemical levels in a pool are in their recommendedranges, the water is said to be balanced.

To save time and money, there is no more important thing that youcan do than to test your pool’s water. It is regular water testing that helpsensure water that is of exceptional quality. Failure to test the pool on a regularbasis will almost assuredly result in extra work and expenditures for you.Water testing should be looked at as an investment in fun, and not as work.Without a doubt, most water chemistry problems are directly attributed to the pool owner failing to takea minute or two each day to test their pool’s water. In order to test the pool water, we recommend the useof Pool WaterTest Strips. These test strips give better test readings than most of the test kits which useliquid drops. In order to use the test strips properly, please take a couple of minutes to review theirinstructions.

Chemical LevelsNow that you have learned how to use the test strips to test the pool water, you are probably wonderingwhat it all means. What is the significance of the chlorine, pH, and total alkalinity readings that you haveobtained? Well, it's chemistry time. But please, if your reaction here is to put the book down, don’t. Wewill keep this as simple as possible.

At this time, let’s look at the items that make your pool water clean and balanced. We will look at themone at a time and will also look at their relationship to other chemicals. (Note, pools using Baquacil shouldrefer to their user’s guide for complete instructions and information on this alternative sanitizationsystems.)

CHLORINE Far and away the chemical that is most closely associated with swimming poolmaintenance is chlorine. Chlorine, in its natural state, is a gas. For home swimming pools, it is commonto find chlorine in liquid, granular, and tablet forms.* The job of the chlorine, as you are probably aware,is to disinfect the pool water. Clean pool water is not only free of debris that you can see, but it is alsofree of bacteria which you cannot see.

3

*Please be aware that chlorine, when used or handled improperly, can be very dangerous in any of its forms. Alwaysread the label of any chemical that you are using, and keep all chemicals out of the reach of children. Store in a wellventilated area away from other chemicals or direct heat. NEVER mix chemicals together.

Another function of chlorine is to act as an oxidizer. In this capacity, the chlorine breaks down wastes thatare brought into the pool by wind, rain, and swimmers. This oxidation process “burns out” small organicdebris that are too small to be filtered out.

When chlorine is added to the pool, it forms what is called FREE CHLORINE. Free chlorine is the formof chlorine which can perform the sanitizing and oxidizing functions. As the free chlorine reacts withbacteria and algae, it is depleted. (Sunlight and heat likewise cause the chlorine to deplete from thewater.) Also, as the free chlorine reacts with dirt, human waste, fertilizers, and other materials, it formswhat is called COMBINED CHLORINE. (Combined chlorine is also called chloramines.) Thiscombined form of chlorine is a much less effective form of sanitizer. As the combined chlorine buildsup, swimmers will notice increased eye and skin irritation as well as a strong chlorine odor. Whilefree chlorine is desirable and needed, combined chlorine is nothing more than a problem causer. Theamount of free chlorine plus the amount of combined chlorine equals what is called TOTAL CHLORINE.

Total Chlorine = Free Chlorine + Combined Chlorine

Because chlorine can be either free or combined, it is important to know what form your test kit is testing.If your test kit uses a solution labeled Orthotolidine, or OTO for short, it is testing the total chlorine level inthe pool. This reading may or may not be useful, depending on how much combined chlorine is in thewater. (Remember, free chlorine is useful, but combined is not useful. The problem with a total chlorinereading is that it doesn’t decipher between combined and free.) More useful to the pool owner is eithertest strips which check for free chlorine or a test kit which uses a reagent called DPD on the chlorine test.DPD kits can give both free chlorine and total chlorine levels. When a test strip or kit tests for free chlorine,the pool owner gets a much more accurate indicator of the “health” of their pool. (For complete testinginformation, refer to your test kit or test strips.)

Now that you have a better understanding of chlorine and the forms that it can take, how do you maintainproper chlorine levels in your pool, and what are the proper chlorine levels? The recommended chlorinelevels are as such:

Free Chlorine - 1.0 to 3.0 Parts Per MillionCombined Chlorine - Under 0.3 Parts Per Million

When chlorine levels are not kept in the recommended ranges, the following problems can occur:

In order to raise the free chlorine level in any pool, you simply add chlorine to the water. The hard part hereis really more a matter of deciding what chlorine product to use. Eastgate Pools recommends SPARCOSlow Dissolving Tablets for daily chlorination. The reason for this recommendation is that slowdissolving tablets need to be added less frequently than fast dissolving tablets, granular chlorine, or liquidchlorine. Large slow dissolving tablets may need to be added only a couple of times per week, while otherproducts may need to be added on a daily basis. Since pool sizes, weather, and usage all affect chlorineusage, it is impossible to say how many tablets you will need weekly. The safest way to know when andhow much chlorine to add is by testing on a regular basis and then adding chlorine based on the testreadings, your pool’s size, and the label’s instructions. A simple test holds the key to your pool’swater quality, and there is no substitute for it.

An even better way to chlorinate your pool is to use a SPARCOAutomatic Water Treatment System. Even if you didn’t get the Cyclerwith your pool package, you can add one if desired. The SPARCOAutomatic Water Treatment System is desirable because you do nothave to handle chlorine, making things safer and less time consuming.Because this system can hold a large amount of chlorine tablets, you mayonly need to replace the treatment chamber every three to five weeks.(Actual time may vary due to pool size, weather conditions, usage levels,and other factors.) Since the chlorinator is dispensing chlorine over along period, the pool owner is better protected against drops in thechlorine level that lead to algae and cloudy water.

Another advantage of the SPARCO Automatic Water Treatment System is that it can save money.Money is saved because as the weather changes, you adjust how much chlorine is dispensed into thepool. With most other chlorine products, you cannot control their dispersal into the pool. Over the courseof the season you will save time and money as well as reduce the chances of water problems by usingthis system. (For more information , please contact an Eastgate representative. If your pool is equippedwith a SPARCO System, please read the owner's manual that came with it.)

The Mineral Reserve System is an advanced system that utilizes the SPARCO Automatic WaterTreatment chamber and allows you, the pool owner, to operated with a greatly reduced amount ofchlorine—approximately ¼ to ½ the normal amount. It consists of two separate components that fit inside.The first is the Mineral Reservoir, which contains silver (for killing bacteria), zinc (combating algae), andcalcium carbonate (for pH stabilization). The Mineral Reservoir will last for the entire pool season, andis easily activated. Just place it in the chamber and water activates it. Inside the Mineral Reservoir isa Bac Pac. This is simply a slow, low feed of chlorine. The Bac Pac will usually last for 2-3 weeks beforeneeding to be replaced.

The Mineral Reserve System minimizes red eyes, swimsuit bleaching, and fading of your liner andincreases the overall quality of your pool’s water. Whenever you bring in a water sample for testing,please let your test person know that you are using the Mineral Reserve System.

Now that we’ve examined free chlorine, combined chlorine, and chlorinating your pool on a regular basis,we can look at what to do when the combined chlorine level builds up in the pool. Remember, combinedchlorine levels over 0.3 PPM are undesirable. Over time, this level will build up despite how well you keepup on adding chlorine to the pool. In order to bring the combined chlorine level down, you must add a largerthan normal dose of chlorine. This dose of chlorine is called shocking, or super chlorinating the pool,and it is 3 to 5 times the normal dose of chlorine. A weekly shock treatment will destroy chloramines,human waste, algae and bacteria.

To shock your pool, Eastgate Pools recommends using one bag (1 lb) of Power Magic Super Oxidizerper 10,000gallons of pool water. Power Magic is superior to liquid chlorine in that it contains sodiumtetraborate. Borates are effective at removing CO2 from your pool’s water. Algae thrive on CO2 and whenthese levels are reduced, algae cannot survive. Liquid shock does not contain borates and is thus, far lesseffective at combating algae.

Pounds of Power Magic = Gallons Pool Water / 10,000

For example, on an 18 x 36 2000 pool with walk-in stairs, shock with 2.5 lb of Power Magic.

2.5 pounds = 24,480/10,000 (rounded)

Shock treatment is recommended at least once per week, but in extremely hot weather with a lot of use,or in rainy weather, more frequent shock treatments may be needed. If at anytime the chlorine level dropsto zero, shock the pool immediately, as the chlorine level may actually be below zero. (This is referred toas chlorine demand.) When the weather is hot, a chlorine level of zero can result in a cloudy orgreen pool within 24 hours. If your pool ever gets a bad algae problem, you may be instructed to usea heavier and more frequent dosage of shock. After shocking the pool, please allow enough time for thechlorine level to drop back down to its normal level before allowing swimmers to use the pool. If the poolneeds to be shocked and used immediately, we recommend that you use a non-chlorine shock treatmentproduct called SPARCO Quick Acting Super Shock. (An Eastgate representative can give you all ofthe details on this product.)

If you selected a chlorine generator, you have chosen our most convenient and advanced system. Achlorine generating system actually converts ordinary salt (sodium chloride) into chlorine, thus effectivelydestroying algae and bacteria. Once done, it converts back into salt, whereby the cycle continues again.You will still need to add liquid chlorine (shock) to your pool to eliminate chloramines and you willoccasionally need to replenish lost salt. Salt used should be 99% clean pellets, such as that used in watersoftening systems, and while we do not sell salt, it is readily found at many locations. Please consult youroperations manual for manufacturer's recommendations. Eastgate Pool's Water Professionals will beglad to assist you with any questions you might have. Don’t hesitate to ask.

pH pH is not as familiar to most people as chlorine is, but it is just as important. pH is a measure ofwhether something is acidic, basic, or neutral, and it is always measured on a scale of 0 to 14. Everythinghas a pH value associated with it. A pH of 7.0 is neutral, a pH under 7.0 is acidic, and a pH over 7.0 isbasic.

pH is important to swimming pool water for many reasons, and as such, it cannot be neglected withoutproblems occurring. On a swimming pool, the pH should be kept in the following range:

Recommended pH Range - 7.2 to 7.6

If the pH is not kept in the proper range, the pool owner may experience the following problems:

8

Of the problems associated with an improper pH, the one that should be of the most interest to the poolowner is the drop in the efficiency of chlorine at a high pH. It is not uncommon when we perform water teststo find pools' with a pH of 8.0 or above. Unfortunately, at this pH level, the chlorine level must bekept 2 to 3 times higher in order to achieve the same sanitizing level as is achieved at a pH of 7.2to 7.6. The result is that the pool owner either wastes money by having to keep the chlorine level at anelevated level or their pool water turns cloudy or green. Neither scenario is necessary or desirable.

The pool’s pH is crucial, and luckily, fairly easy to test for and adjust. All swimming pool test kits shouldtest for pH, and by now you’ve probably become familiar with how to use your test kit or strips. Once youhave tested the water and obtained your results, you can make any needed adjustments to the pH.

If the pH tests low, you will use SPARCO pH Plus. To determine how much pH Plus to add, you will needto know your pH test results and your pool’s capacity. The label on the container of pH Plus will then instructyou on how much product to add.

If the pH tests high, you will need to add SPARCO pH Minus or Muriatic Acid. SPARCO pH Minus isa granular product where as Muriatic Acid is a liquid product. (For safety reasons, pH minus is normallythe preferred product to use.) To determine how much pH Minus to add, carry out the same procedureas described for a low pH. When adding pH Minus or acid, never add it through the skimmer and, choosean area away from metal ladders or other metal components.

For you and your family's safety, always wear protective goggles and gloves when handlingmuriatic acid. Wash any spills off of clothing or pool decking and equipment immediately.

TOTAL ALKALINITY No discussion of pH would be complete without looking at total alkalinity.Total alkalinity is a measure of alkaline materials in the pool water. While this doesn’t mean much to mostof us, what is important is that these alkaline materials play a significant role in helping to maintain thepool’s pH. These alkaline materials help prevent changes in the pool’s pH. At proper total alkalinity levels,the pool’s pH will be more stable. This stabilizing is referred to as buffering the pH.

On vinyl lined swimming pools, the total alkalinity should be kept at the following levels:

Total Alkalinity - 80 to 150 Parts Per Million

Hardness Level Problem

Calcium HardnessToo Low

In the event that the pH and total alkalinity both need adjusted, always adjust the total alkalinityfirst, since this acts as a buffer for the pH.

CALCIUM HARDNESS Calcium hardness is a measure of dissolved calcium in the pool’s water.For the most part, calcium hardness is not an item that the pool owner needs to monitor continuously.Having Eastgate check the water several times a year is sufficient in most cases. The reason for notneeding to have this tested as often is because it does not change near as quickly as the chlorine, pH,and total alkalinity do.

The calcium hardness should be kept in the following range:

Calcium Hardness - 120 to 300 Parts Per Million

If the calcium hardness is out of range, the pool owner may see the following problems:

Since calcium hardness will usually be tested at our store, any recommended action , if needed, will beprescribed when we test the water.

Please note that soft water is NOT good in pools and spas. Soft water is highly corrosive and will leadto corrosion on any metal component, such as ladders, skimmer screws, and incandescent light housing.In addition, soft water is very difficult to keep in balance. Again, just bring in a water sample and we willbe glad to analyze your water and make professional suggestions.

Specialized Chemistry Considerations

Even the best cared for and "balanced" pool will need a few other chemical additions to its water to keepthings looking clean and clear. The swimming pool industry refers to these other chemicals as "specialtychemicals." These specialty chemicals help reduce overall chemical usage as well as maintenance time.

CYANURIC ACID Of all the specialty chemicals, cyanuric acid is among the most important.Cyanuric acid is important to the pool owner because its use can help reduce the use of chlorine.Cyanuric acid, which is also called stabilizer or conditioner, helps to reduce the rate at which the sundepletes the free chlorine in the water. By slowing the depletion rate, less chlorine willbe used. Since chlorine is the biggest chemical expense that a pool will have, it makes sense to makesure your pool is stabilized. The cost of stabilizer will be made up for in chlorine savings.

Many forms of chlorine have stabilizer built into them, requiring the pool owner to only have to establishthe initial cyanuric acid level. Once this level is established, a stabilized chlorine will be able to maintainthis level unless significant amounts of new water are added. The recommended cyanuric acid level isas such:

Cyanuric Acid - 30 to 125 Parts Per Million

The result of too low or too high of a stabilizer reading are:

Historically, we do not see many cases where the stabilizer level is high enough to cause the chlorine notto work, but it can happen if not enough fresh water is added to a pool over time. On a new pool, especially,this chlorine lock is not something to worry about.

For the most part, test kits designed for home use do not test cyanuric acid. Cyanuric acid is easily testedfor on our professional equipment, and we will be happy to test your pool's water anytime that you havequestions or concerns. After we have the test results, we will advise you whether or not SPARCOChlorine Conditioner & Stabilizer needs to be added.

ALGAECIDE When you look at pool problems, the most common one is without a doubt, algae. Thereare several reasons for this problem being so widespread. The first reason is improper maintenance.Inadequate chlorine levels, improper water balance, and improper filtration can all play a part inthe growth of algae. Because algae can develop in such a short time, the importance of regular testingcannot be stressed enough. A couple of minutes can save you countless hours and dollars. But moreimportantly, the small time investment keeps your pool fun, which is probably why you purchased it in thefirst place.

The second reason why algae is such a common problem on swimming pools is that algae is a very toughand resourceful plant. Algae is a primitive plant, so it is definitely not a new problem. While properchlorine and pH levels will go a long way towards preventing algae growth, there will be times that for onereason or another, the water chemistry is not exactly where it needs to be. It is for this reason thatSPARCO Algae Destroyer should be used on a regular basis. Algae Destroyer is a broad spectrumalgaecide which not only kills algae, but also helps to prevent its emergence. The use of Algae Destroyergives the pool owner another line of defense against the most common pool problem. On a weekly basis,you should add 4.3 to 8.6 ounces of Algae Destroyer per 10,000 gallons of water. For convenience, werecommend adding Algae Destroyer each week when you shock your pool.

If your pool does get algae, the first thing that you will need to do is to check and to adjust the water balance.The pool should then be shocked and a dose of Algae Destroyer added. (See dosage rate on AlgaeDestroyer for a pool with visible algae growth.) It is important that these treatments beginas soon aspossible due to the speed with which algae can grow. Also, algae is easier to kill when it is immature.The longer algae is left untreated, the more of it you will have, and the harder it will be to kill. Duringtreatment for algae, the filter should be run continuously until the problem is remedied. (See Filtration &Vacuuming sections of this manual for more tips on dealing with an algae problem.

METAL REMOVERS Depending on the source water for the pool, metals may be present in thewater. Testing for these metals will be done by your pool dealer, as few home test kits will test for them.(The most common metals tested for are copper and iron.) If metals are found in your water, an Eastgateemployee will instruct you on how to handle them. If these metals are not removed or made “inactive”, theycan potentially cause staining.

IMPORTANT NOTE: If your pool's water turns colored the first time chlorine is added, it is probably dueto metals in the water. The chlorine oxidizes the metals which leads to the discoloration. To remedy thisproblem, bring a water sample to Eastgate Pools and we will analyze the water and make recommenda-tions on what steps will need to be taken. Fortunately, this is a very uncommon problem.

12

WATER CLARIFIERS While algae is the number one pool water problem, cloudy water is not farbehind. In fact, in most cases of heavy algae growth in a pool, the pool will go through a cloudy phase eitherbefore green is visible or after the green is gone. (Note, cloudy water can have causes other that algae,but proportionately, algae is the number one cause of cloudy water.)

In the early stages of algae growth, it is quite common for the pool walls and bottom to get "slimy" whilethe actual water begins to turn cloudy. If not shocked and balanced quickly, the pool water will quicklyprogress to green. If at anytime you see cloudy water developing, immediately check the pool's chemicallevels. In most cases, the chlorine level will be very low. The quicker the pool is shocked and balanced,the better the likelihood that a major algae problem can be avoided.

Cloudy water is also a very common problem after a pool has had a major algae problem. The reasonfor this cloudiness is that after the pool has been shocked and treated with algaecide, the algae may bekilled, but it just won't disappear. The dead algae remains in the pool water leaving a milky, or cloudyappearance. These dead algae cells are very difficult to filter out due to their extremely small size. Whenyou are fighting a major algae problem, you should expect to see the water go from dark green to lightgreen to cloudy. As you see these changes taking place, you will know that the algae is being killed.

As was mentioned, dead algae is very difficult to filter out. In order to help the filter, clarifiers are used.Clarifiers work by taking small particles and helping to clump them together so that they are easier to filter.Clarifiers come in varying strengths, and for extremely cloudy pools we recommend SPARCO CrystalClear clarifier. In some cases, a clarifier will not be strong enough to do the job, and in these casesSPARCO Super Floc should be used.

In the event that your pool has a clarity problem, Eastgate Pools will be happy to test your pool's waterand make recommendations on the proper steps to take to remedy the problem. Our hope is that withthis manual and with our personalized help, we can help you maintain your pool so that you never needto worry about cloudy water problems.

CHLORINE GENERATING SYSTEM

This is one of the easiest ways to keep your pool chlorinated. With the Chlorine Generating System,salt is added directly to the pool water. The Chlorine Generating System then generates chlorinefrom the sodium chloride compound. It is also equipped with a "super chlorination or boost" settingthat will further reduce daily maintenance. For specific operation please refer to your Chlorine Gener-ating System owner's manual. When having your water tested by an Eastgate Pools water expert,please remember to advise them that your pool is equipped with the Chlorine Generating System.

CHEMICAL SUMMARY The preceding section has given a fairly detailed overview of swim-ming pool chemistry, and it may have you wondering just what you've gotten yourself into by purchasinga pool. Fear not! If you test the pool on a regular basis, paying close attention to the water'schlorine and pH levels, pool problems will be minimized. The vast majority of pool water problemsare created when the chlorine level is allowed to drop below its acceptable level. When you add inimproper pH levels, problems soon develop. A couple minutes investment on your part to test the waterwill pay huge dividends in time, fun, and money. The other chemical levels and chemical additions areimportant, but the chlorine and pH levels are absolutely crucial.
