I currently have in my 46gal. bow front a Lifegard Quiet One model R175254V. It is supposed to be rated at 1140 gph
at full flow and yields 724 gph
through a 1" line at 4 feet. The pump currently has a 3/4" line. I need to use two maxi-jets 1200 PH for more flow. I've been thinking of eliminating the PHs so the tank looks better.
I would like a pump that will give me enough GPH
to have three spray bars, one to go the length of the tank, one to go the width of the tank and another that goes down to the bottom with water coming out at 90 degree angles.
I would like the pump to be as quiet as possible. I would like the first two spray bars to break the water surface and to have another row of holes at an angle of maybe minus 45 degrees.
What would be a good PVC
I.D. for the recommended pump? I was thinking of using the widest allowable by the pump and then use reducers to perhaps half an inch for the spray bars.
I.D. would you recommend for the spray bars?
What size in diameter should the spray bar holes be? 3/16"? more? less?
How far apart should the holes be drilled from each other?
I was thinking of a closed loop on a timer for running just in the day time(if the pump is too noisy) and just leave the regular pump on all the time. I've read that some people who use closed loops use the Aqua Clear prefilters on the intake of the closed loop. Should they be used with or without the filter media(which would be cleaned weekly or bi-weekly).
I would like it to be the first option since I don't have much room under the tank.
