i was talking to a friend of mine thats not familiar with sumps or anything like that as i am not too familiar either. he said i can take to filters that are the same models ex fluval 305s. put the inlet in the tank the outlet to blow out into the beginning of the sump. then take the other 305 inlet in the sump and out let in the tank. he said the that would be easy cause flow would be correct. It made sense to me but idk seems like somethings wrong. is it possible would it work? any benefits other then not having to buy a sump pump?
