If you are looking for free canister filters to go with the free tanks you got from Josh, you are at the right place. Some of them might still work, but they are definitely good for parts. They are all Rena/Api canisters that include all the baskets and foams, but no media.
I would be interested in a couple of parts(hoes/tube extensions that extend into the tank. I wouldn't want all of it because I'm sure someone can use them that have many tanks. I'm located in Southern Frederick county so I'm not too far away
