Booms cube-80

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

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.

hey man i see that you went with the 45 in stead of the 90 you will see alot better flow and less head loss on 45 then 90 and it looking pretty fancy now
