A friend of mine walked into the petshop and saw some used canister filters in an old box. He asked how much, and apparently the lfs just wanted to get rid of them, so he got them for free. Four 55 gallon filters. Two 10 gallon filter, and a 20 gallon filter. For free. In good condition. Recently, his wife was complaining so much about spilling water on floor when he did water changes that he got rid of the aquariums. Who would take all this stuff? Perhaps his neighbor, the fish freak. So i got a 10 gallon aquarium, a 20 gallon aquarium and several filter. now I just need to clean out the tank. Only problem is I dropped one of the filters and the motor fell out. Can i put it in or not?
