Sorry...Im confused again.

Basically.

I have a ASM G3, ignoring the tank size it's rated for and the circulation pump rating (Sedra 5000 @500gph) it supposedly can process ~200gph (though I'm feeding mine with a MJ1200 I had around). If it was the only thing I had in my sump, technically running anymore water past it than 200gph is overkill. Now of course lots of other thing come into play and there are no rules, the idea is just to give a starting point.

Having said that, I'm probably pulling a 1000gph through my sump (it's also though a refugium), but I'm happy, tanks happy.
