i have a 240 that has an fx5 and a aqua top canister for a 200 gallon tank i want to add another one that is strictly mechanical. i want this because the fx5 is not a mechanical canister what so ever. i want to keep it under $200 and i want as much flow as possible. i saw one on her that was way tall at had a flow of around 1500 GPH but can think of the name. so tell me your opinion on the best mechanical canister.
