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
