So while doing a a water change tonight I unplugged my canister only to find it leaks water all over the floor. Now it only seems to leak when I turn it off but I'm not sure if I'm willing to risk 70 gallons of water in my living room. My question is this I also run a sponge filter, would this be enough to sustain life over night until big ALS opens tomorrow morning at 10 if I can't get this piece of $&@! To stop leaking?
