I just got a used Wet/Dry Trickle sump filter that I want to attach to my tank.
It was used on Freshwater tank from a friend who has been disease free with his fish, but there is some bacteria on the bio balls and some of the sponge filters, is there anything I should be treating that filter with before I add it to mine?
