Plumbing Question???

Durwood · 02-04-2007, 12:08 PM

Hey first post ever,will try not to screw it up.I am setting up my new 135 gallon acrylic,my question involves the return lines from sump tank.I think my return pump is a 400-600 gph range with a 1" intake and a 3/4" return.I want as much return pressure or forceful current as possible but I have to "T" the return each end going to spraybar at seperate ends of tank.Would I be better off using 1/2" pvc to create more pressure or should I use 3/4" pvc like the pump is designed for,and would this create less flow and or pressure because it is "T"d??Hope this makes sense.

Use 3/4" pvc or use a pvc "Y" and then run flexible hose to each ends return line. T give you an extra 1 foot of head preassure. What pump are you running? 600 gph is really low for a 135 gallon tank. What are you wanting for a tank? FOWLR, FO, Reef?

I have an existing 75g fowlr tank that I am going to transfer to the 135g,but I want to try some simple corals,I heard mushrooms are good starter.The pump I got doesnt have any legible i.d. on it,I will probably upgrade in the future,did you say that a T fitting will increase head pressure,meaning less flow,so I should use a "Y" instead,is this correct?

"a T fitting will increase head pressure,meaning less flow,so I should use a "Y" instead,is this correct?" That would be correct

using smaller pipe & more fittings than you need will do the same. use 45deg fittings instead of 90 deg fittings for less restriction.

Since I dont know what size pump I have,what size do you recommend,Im trying to keep it in the $100-$150 price range.My tank is a 135g

Go to a Hot tub or spa place and pick up a Used spa pump. They will work very well under preasure and last forever, plus they run cheaper than any pump on the market, for the flow that they have.

Thats a good idea on the pump,thanks for the tip.

i have a 135g, i bought a Mag 9(900gph) for the return & a Sequence Snapper(2400gph) for the CLS. I plan on cutting off the CLS at night to similate calmer seas at night.

JoJo this is a hijack but I wouldn't kill your closed loop at night. First the flow at the reef stays pretty much the same at night. Second I would be concerned with stagnant water in plumbing for closed loop. I know a canister shut off for a few hours stinks real bad.

Very true about the stagnant water.....thanks Steve. for some reason i thought water calmed at night.

sorry
