yeah its because im not working right now, so i have to keep busy and i really want to get this thing filled with water.

and now thinking about my pumps, i kinda wish i had a stronger pump for the return, my drains can handle the flow, so at least i know in the future i can always upgrade to 1500 gph if need be.

Here it is with the background done, im liking it, but really because its deeper than im used to, im not really looking at the background alot. i also finish most of my manifold too, just waiting for my bulkhead to line it all up.








i wish i had a nice camera like alot of you, then i could actually show what the tank looks like in person all i have is a HP Photosmart hahah oh well.

not really sure what to do here, i was just thinking instead of putting my return through the manifold i could use the 2 holes in the tank. the only thing i would be worried about it 1. that the CL is no longer a CL due to running through a manifold and 2. unless i put the nozzles pointing to the surface i would get alot of drainage from them, never used locline and was wondering if it would still drain all the way to that level.

Anyone know how to create a good syphon break in the return, considering that my 2 returns are quite a bit lower than the overflow?

that is easy my friend
just drill a hole in the return pipe just above the water line and that will act as a siphon. I would put it in the back facing the wall of the tank thou so you dont get any spray thou IME

do you mean in the sump part or in the tank part?

He was talking about the Tank water line. Which means for a siphon to work, your return plumbing needs to higher than the water line... You will usually see a siphon break on plumbing that comes up over the tank rim and back down under the water.

That's why I suggested check valves, because I was (and still am) under the impression that your return plumbing comes back in on the top 2 bulkheads on the back of your tank?

Use some True Union Check valves?

I've had then on all my tanks, and never failed me.. the swing gate has no metal springs to rust, so should never stick open.

i was thinking check valves but they can fail and it reduced flow on the pumps but alot.

I'd never build a system without them... and because there isn't any metal parts there really is no place for it to fail. At least not on the ones I use. It's just one extra fail safe..

Based on how low your returns come in on your tank and siphon break is going to be tricky becuase the water is gonna drain down to those return bulkheads, which is why I gave the suggestion of check valves. Unless I missed something on your plumbing system.
