3/4" return line down to 1/2" RFG?

[don_chuwish]

I'm slowly building a 20G cube. I plan to have a single return nozzle and I'll be using a Jebao DCP-2500. The smallest barb fitting it comes with is 3/4". I will be testing it to see what setting produces about 200GPH and have that as my target flow.
Any problem with reducing at the bulkhead down to 1/2" and use 1/2" loc-line to 1/2" RFG? Hoping to keep the fittings simple by using a reducing elbow, barb x male NPT, 3/4" to 1/2".
Sound workable?

Sure - the easiest way would be to leave the 3/4in bulkhead and add a 3/4in NPT fitting, then add a 3/4in to 1/2in reducer

From there you can either add the 1/2in RFG to this, or add a few segments of 1/2in Loc-Line between the reducer and the RFG.

Thanks! That may work better also because I already have a diamond hole saw for 3/4" bulkhead. But in terms of plumbing fittings I'd rather do 1/2" bulkhead and a reducing elbow:

3/4" BARB X 1/2" MALE NPT
into a 1/2" bulkhead (thread x thread)
Just means fewer 'conversion' pieces.

Hmnn, $17 for a 30mm diamond hole saw, or a few extra PVC fittings... oh the drama!

Oh! Now I see what you mean - yeah that Loc-Line adapter makes it clean enough!
