Hi,
I am helping with a tank that hasn't had media changed in like 6 months, (maybe more). It is a Magnum 350 canister. When I change it I will be using the poly fiber stuff in the bag from wal mart. My question is, it is very dirty, and I am worried that if I change it all at once some of the biologic balance will be missing and the tank will start a cycle again, or something worse.
(4 mollies and a pleco),in a 45 gallon tank, but I hear couple have died recently. Checked water quality with strips, and surprisingly that all seems right on... Just don't want to cause a bigger problem.
Thanks
