I have an overflow box setup with two hoses running down to the sump. The sump is a 29 gallon tank. I have a (drilled on bottom) 5 gallon bucket that sits on the top of the 29 gallon and drips into the tank. The 5 gallon bucket is full of bio balls. Could I have both hoses run into the 5 gallon bucket, and put filter socks full of botton on the end of the hoses for mechanical filtration? I was also thinking of putting carbon in the sump itself to help with any odors that may arise. I was told the pump does about 900gph. Would this work? I am gonna draw a pic so you guys can better understand. (visual learner here)
