Water movement is one of the most important
requirements for coral health
90 gallon tank shown
Water movement is important
• Corals are sessile animals
(attached to rocks)
• Moves food past them for
capture
• Removes waste and allows
respiration to occur
• Photosynthesis and
calcification rates increase
Selected Design
Rotational Diverting Valve
•
•
•
•
Single inlet
Alternating outlets
Low geared motor drive
Single pump allowed to
run continuously
Design Revisions
• Simplify machining
• Reduce material cost
• User friendly
– O-ring seal
– Disassembly for cleaning
• Adjustable motor mounting plate
Design Revisions
• Variable speed controller
– For prototype model only
• Ease of installation
Technical Analysis
• O-ring selection
EPDM selected for saltwater
• Estimated flow to be 18 gpm
(6 ft of head loss)
• Fittings selected and sized for
reduced losses
• Removable submerged jet manifolds

Test Plan
• Visual flow indicators:
streamers, neutrally buoyant dyes
• Estimate in-tank flow velocity
• Submerged jet manifold location
• Check noise level
Potential Problems
•

•
•
Possible o-ring failure
Gaps around cylinder at closed position
Verify theoretical concept
Valve body is bulky
