If you are planning on doing daily visual checks of your system you'll be fine. Also if you have room, run slightly over-sized drains. I run standard 1.5" dursos. If you run your overflows at half their max flow rating then you'll have headroom in the off chance a drain should clog as well.
Can you split the return into 2 independent returns, or does your tank only have one spot for return plumbing? ...Maybe I misread your previous posts... Is the Sea Swirl going to be your only return?
Miracles thought that 3 independent 1" drains would be best in this coast to coast overflow which is 18" wide. Thats the widest we could go because the tank is in a closet and we need the room on each side of the overflow to fit the tank in. So to run the 3 - 1" overflows at 1/2 the max I would do that with true union ball valves? I just got the mini Maggie Mufflers in.... I see no way a big snail could ever clog the drains, especially all 3 at once, each drain pipe will have their own separate flex pvc pipes to the 3 inlets on the sump. All independent of each other. Two into filter socks, one into the refugium.
I could do as many separate returns as I want I guess. They have to be on the ends though (front and back are viewable sides) and I have to keep in mind the coast to coast on one end. My thought was to put one 1" Sea Swirl (rated at up to 3600 gph) on the opposite end of the overflow (thats where Sea Swirl recommended for the 1st one) and have 2 Vortech 40s at the overflow end. Sea Swirl thought a 2nd Sea Swirl would work on the overflow side. If thats the case do I need 2 Vortech 40s? Would 2 returns be too much flow through the sump? I could plump for a 2nd return on the overflow side, and see how the flow is and if needed add another Sea Swirl.
