90 gallon canister filter. You will need to buy the pipes and all for it. I used all the parts for my new canister since I upgraded it. It works perfectly and quite. All it need is cleaning inside (I clean it before but needs 2nd round of cleaning). I'm asking 50 (or best offer maybe) for it or im open to trades for turtle stuff (food, stock tank, small male dog clothes and/or accessories, or let me know what you have but must be pets only stuff) these are over 200$ brand new but it has been used though.
