Yesterday I moved around my stock in my 80g and 135g due to some recent aggression in my 135. During the process of removing decor and netting fish, a ton of sand was kicked up and then my filter (
AC 110) started making this horrendous noise and stopped working. I have tried cleaning it, and I have not been successful fixing it. I am looking to replace it next week (I have another filter running on the tank), but I am wondering if there is a way to keep this from happening. Would a pre-filter sponge work?
