return line help

[valgae]

I have a 70g want to add a sump(flow thru) also a closed loop design. i was thinking bout 20gph flow. so im going to do 2-1" OF drains with 2 1/4" bulk heads. not sure what to do exactly for the return?

also is that too much goin through the fuge? someone help!

one more thing should i drill one return and use a tee in the tank or drill two seperate return lines?

Well, 20gph isn't going to be enough. Not even close. You'll wanna shoot for more like 700 gph through it. I think you had a typo too, 1/4in bulkheads? You'll want 2- 1 1/4in drains, you can do 1in bulkheads, but if your gonna drill, then you might as well do 1 1/4 bulkheads. The return would best be 1" T'd to 2 3/4in returns.

yeah its a little late here. so OF pvc should be? bulkheads? drilled hole size?

Do 1 1/4, buy your bulkheads, then drill according to them. There are several different styles available, many have different diameters.
