Its been running for about a year now and the last few months its been turning on and off so i think i'm due for a totally new filter, plus i need a bigger tank anyway. My current is 20 gallons. I want at least a 40 gal
. Anyway- getting off topic.. my initial question is: What can I do to keep my fish alive until i buy a new tank with a new filter? The water looks quite gunk-y at the moment...im going to do a water change soon. What are some things that could happen to my fish without a filter? Will they be okay for 2 weeks until I buy a new one?
