Question on sump flow

sean A. · 09/03/2009, 11:59 AM

I have a 240g RR FOWLR tank. For the drain I a using 1 1/2 inch
Bulkheads. For the Return I got 1 inch bulk heads but my LFS
sold me 3/4 inch Bulkheads instead for the return. Will this still
Work or should I just switch the 3/4 inch Bulkheads to the 1 inch
for the returns.

How much flow you planning on having?

Run you return lay out through the Head Loss Calculator to see if the difference is worth bothering.
