Catch and Release
My filter went out tonight and I can't get a new one until Friday at earliest. My question, how long can I go without a filter. It is a 35g tank with about 25 fish in it. Well under the limit. There is plenty of aeration, and if I have to I have a spare 10g filter as last resort until then. Will my tank be okay without a filter for a few days? Should I put that 10g filter in, or will I HAVE to get one earlier than then?
