I dont exactly feel like spending $50-100 for an overflow box so I was thinking the other day and came up with this idea. I have a CA
1400 pump/powerhead. I bought it for my protein skimmer but then realized what else I could do with it. If I buy two pumps, I can have one to bring water up to the tank from the sump, and one to pump water out of the tank and into the sump, now in my mind this should work out evenly if I use the same kind of pumps. But I am not sure if any other factors will interfere such as gravity, water pressure, etc. This would save me up to $50 by not buying an overflow box and seems full proof to me.
I just thought I should get "approval" from you guys out here. I want to make sure there won't be any problems before I go ahead.
