Curious, how can you make that determination without any information about the system?3/4" on the return

I think in most cases 3/4" is fine for a 75, but the OP mentioned a Sicce Syncra SDC 7.0, which looks like it comes with 1" and 1-1/4" output sizes. For this reason, I'd say go 1" on the returns.

Interesting. Wouldn't you want the overflow to be able to handle Niagara Falls if needed (exaggerating, of course), and make the return pump the limit of what can flow through the system? This way, the return pump even at full blast cannot out pump the capacity of the overflow and cause a flood. I'm genuinely asking. Thank you!You will have the same number of return lines as drain lines. You want a larger drain then return. Your overflow will be the limit on flow rate

I'm sorry, large drain then returnInteresting.

The overflow has a max gph, you have to turn the pump down to what the overflow will flow. On a 75 I would run 600gph at the top on a overflow rated for 800. Plenty for a 75. He chose a return that will need to be choked to 3/4 inch.Interesting.

It's all goodFor the record, OP edited their post… At first the only information was “75g tank, what size pipe?”. Anyways, face saved
