hey guys i'm new to this but i been doing alot of resaerch, i was seting up my 180 gallon fish tank, i have a king 5 water pump, rated at 1,550 gph, a custom wet/dry filter made from a 20 gal tub, and a diy pvc overflow, that i tend to put 10 red belly piranhas, i have 3/4 house running from the pvc overflow to the sump and the pump back to the tank, when i ran it, it seems that the water tends to leave the wet/dry filter too fast but at the same time it looks like the pvc overflow doesnt seem to remove the water fast enought from the tank to the sump, any thoughts on how i can fix this, thanks in adv, guys
