I'm sorry to hear this! Yeah it sucks! A while ago, my filter spilled about 10 gallons of water from my tank right onto the floor in my room

I know it wasn't as bad as your incident was, but believe me ... I was so furious! It was a LOT of cleaning up. It happened very late in the evening, so I was up half the night cleaning up the mess. The water soaked all the things I had hidden inside my aquarium stand! The filter is a canister filter (Rena Filstar XP3). Apparently, I didn't cover the filter properly (after I cleaned the filter media) and that's why water started pouring from the outflow tube. I guess we all have to deal with disasters of this type every once in a while in the fish-keeping hobby ...
