i sucked on the intake of a canister for 1 hour so it could work again, this was a few days ago... i was moving my fish into their new tank and had them in the rubbermaid with the ehiem 2215.
The other thing i did was sit in the basement for 4 1/2 hours due to my jaguar jumping out of the rubbermaid.. this happened all in the same day, i sat there just incase he wanted to bail again..
Oh and i also skipped 3 days of school + 2 weekend days to set up the 180
