Water movement is one of the most important requirements for coral health

90 gallon tank shown

Water movement is important

• Most are sessile animals (attached to rocks)

• Moves food past them for capture

• Removes waste and allows respiration to occur

• Photosynthesis and calcification rates increase

Basic Design

Rotational Diverting Valve

• Single inlet• Alternating outlets• Low geared motor drive• Single pump allowed to

run continuously

Plumbing SchematicPump Outlet (2 Places)

Magnetic Drive Pump

Diverting Valve

Pump Intake

Design Revisions

• Simplify Machining

• User Friendly– O-ring seal– Disassembly for cleaning

• Adjustable Motor Speed/Mounting

• Ease of Installation

Technical Analysis

• O-ring Selection

• Flow Energy losses – Pump-Outlet

• Removable Submerged Jet Manifolds (Spray Bars)

Test Plan

• Visual Flow Indicators: (Streamers, Neutrally buoyant dyes, etc.)

• Measure In-tank Flow Velocity

• Submerged Jet Manifold Location

• Measure Noise Level

Problems?

• Possible O-Ring Failure

• Gaps around Cylinder at closed position

• Verify theoretical Concept
