right? That's so that your protien skimmer or media reactors have time to process the water.... of course this may or may not be true. But it was something that stuck in my head once.
given that my system volume will be around 90ish gallons. 5 times would be 450. so if i remember right a mag drive 7 would work. and if we say that a 1" pvc
overflow can flow 600gph, i keep seeing that number over and over again. i should be good.
