    Hey gang!I would like to replace the sponge in my ac 50,so i am currently running 2 sponges,filter floss and bio chips(no carbon).How long should i run both sponges before i can throw the old one out?

    It's really not necessary to replace the sponge until it is falling apart. You can just rinse it in old tank water while you're doing water changes. I have some that I've been running for 5 or more years.

    What are bio chips?

    Harpua is right, you don't need to replace it until it is falling apart. However, if you are going to replace it, I would suggest running both together for at least a month. The longer, the better.

    Maybe bio chips is an improper name but thats what i call them,they are the little ceramic like rocks that house beneficial bacteria.
