Ha ha I was looking for an answer on if this type pump would work thanks. I am building my first system and have an intex 8' pool and was thinking of using it for the fish tank however I don't have room for the pool so am building a tank and thought I could still use the pump. I got the whole pool and pump off craigslist for about $30. Mine says it pumps 530 gallons an hour my tank will probably be somewhere around 500 gallons not sure till I get it built. I take it you are not using the filter that goes in the pump? Are you using anything in place of the filter or just leave it out?Originally Posted by badflash
