Or you do turn the power back on but forgot to open the valves, and the impeller is going for 2 days before you realize the valves are still closed...![]()
Depends a lot on the filter, how often you do it. Best case it just gets hot. I've had pumps get hot enough though to deform the impeller/motor housing.what will happen? Because i usually close the valves and leave the filter running till my water change is done.... depending on which tank... 1.5-2.5 hrs each time
once i forgot to open the valves till the next water change which is a week later ... had to wash the canister filter
I've flooded my living room (still do) many times while juggling maintenance between my 2 tanks. Might be doing it again in a few hours from now.

So your options are the water goes stale vs the water goes stale and your canister filter motor overheats? What are you gaining by leaving them on?It's a weekly thing when i do water change, touch wood so far so good.... i always thought there is still water in the canister so no reason to overheat..... while if i off the canister during that period, the water may go stale
