I currently have a 75 gallon with 20+ live plants and 3 pike cichlids. This is my first tank but will be buying a much larger tank within a year maybe a 220 gallon or 300 gallon. I currently run a penn-plex Cascade 700 canister filter and it seems to do great but i am looking to upgrade. I am leaning towards the fluval FX5. My only concern is that I really like the filter i have because of the sprayers along the back of my tank provide great circlulation and air. Is there anyone that sells similar attachments for the FX5 I would like a sprayer the is around 46" to cover the entire tank.
