the SW guy at big als said "the most you're going to get out of an overflow box that hangs and is not drilled into your tank is about 600gph which is about half of what you need, you're wanting to get at least 1200gph of flow circulating the water in your tank"
is this true or is he just trying to make me spend more money on a sump? lol
he also said overflow's are very noisy but, i thought they just dragged water down a tube by gravity, not a pump.....so why would that be noisy?
oh wait I'm assuming its like a sink that's constantly draining right? so you get that sucking noise, im also assuming that they make silencers for them and one the overflow has leveled out and everythings running that noise stops
also how does heating work for a tank? like the wattage, how many wpg kinda thing
