1" returns - How to use loc- line

president89 · Dec 4, 2017

I built a 48" tank with 7 compartments for housing clownfish pairs. Each compartment has 1" return and 1" drain via bulkheads. I didn't realize they didn't make 1" loc line until after I was done drilling. How do I maximize the 1" return? If I reduce the 1" bulkhead to a 3/4" I'm thinking that I lose return capacity.

The compartments are only about 10" high and 7" wide x 10x deep(front to back). The return bulkhead is very close the divider. Is there such thing as a very narrow Y fitting?

Would you be able to modify one of these? They come in 1” fittings.

I could but since I need 7 of them $21 ea is hard to swallow.

How about these in place of Loc-line nozzles: use 45 degree elbows to adjust your depth and then put these on the ends to defuse the water flow and prevent critters from entering the pipe. I use them from time to time. Hope this helps. Cheers!

I feel like those would diffuse flow instead of direct it. Thanks for the input.
