i went to lowes yesterday and saw they had a biological pond filter for ponds with fish. it looks very much like a canister filter and also uses a mesh like disk you fill with carbon in between the sponges. now in order to use this filter on the tank i plan to build (300+ gallons) i would need to use a pump that i can burry in the substrate whitch i think is awsome. the pump and filter are 1500 gph whitch should keep my tank prity well filterd (i plan to do discus) and to break the flow from the return i plan to build a shelf into the tank with rock almost like a waterfall type affect whitch should also keep from makeing to much of a curent whitch iv read the fish dont like. .... so what do you guys think? is this actually doable? anyone have any exp with useing a pond filter to filrter their tank?
btw the filter only cost like 125$ if i went to my lfs and got something with the same gph it would cost me 400$ and the pump is like 50$ and i can also add a uv steralizer for another 100$.
