ok well i guess they deleted to wrong one, anyway i was wondering if a do it yourself overflow could be made like the ones on here, just at a larger scale??
Basically instead of using 1/2 or 1 inch pvc, use 2 or 4 inch??? Would it work??? Any ideas on the flow rate????

The only problem with going with larger sizes is that you have to have increased space behind the tank and above the edge that it is mounted on. If it is going to go under a hood, make sure the hood is tall enough for the higher pipe fittings.
well i was going to do 2 4 inch the tank is 520 gallons or so so i need alot of flow, i guess i could just build a second overflow for the other hole that is drilled in the bottom of the tank but it is in the front so i wanted to avoid it if i could go another way. I was gunna use ABS because it is black so it wouldn't be to noticeable because the backround it black. Also the tank will be sitting about 1 1/2 feet from the wall already so space is not an issue (my sump doesn't fit underneath it and i don't want to make it any higher otherwise i will not be able to do maintnance because the hood will only lift a few inches until it hits the roof
Using the following input parameters
Gallons per Hour = 1250
Drain and Overflow sizes are calculated as
Recommended minimum drain pipe diameter = 1.46 inches
Recommended minimum linear overflow size = 19 inches
using the above two 1.5" pipes would give you aprox. 2500 gph flow, how much is needed on 520 gallon tank?
