I have a 100 gallon tank and am using two canister filters. I plan to run these for a while but would like to uprgade to a sump. Unfortunately the online ones look pretty expensive so I thought I could build one. I have a 20 gallon tank I could use. How would I go about it. My tank is not drilled nor does it have overflows. Any advice would be appreciated.
