3/4 or 1/2 pipe?

How big is your sump? I think people recomend 10x sump volume I believe. That always seemed slow to me though.

75 gallon DT with a 55 gallon sump ;D doin it big

 

This from tank to sump or up from return pump? You gotta be careful with return pump plumbing because of head pressure.

 

I decided on 1-1.5 inch pipe but am now in the decusion of what type of overflow to get an how nuch of a return I need. but the origional thought eas to have a closed loop with nothing but 1/2 inch pipe and would that still be an option.

 

Use 1.5" on your overflow and 1" with a ball valve for your return. You could go with a Hydor Rio+ 2500 for a return pump this will give you about 750gph flow. You then put a T on the bottom of your overflow to the sump with a ball valve on the refuge side to regulate flow to the fuge. Put your return section in the middle with both your skimmer and fuge sections feeding it. Drill your tank for both the OF and return and put a lockline Y on the inside of your tank for the return to disperse in two directions. Hope this helps.

 

yes exactly what I was wanting to do on the sump and was trying to figure out how to plum it LOL thanks

is ther e any way I gould get more flow that 700 gph or is that enough for the set up like that with powerheads in the tank to help with the rest of the flow?

and yea I jacked up the whole thread LOL

 

700 is plenty imho

 

lol i hope ;D if not I have to do a closed loop and that aint gonna happen so It will have to do LOL.
