Power outage advice

[Hemali]

How do I keep the bacteria alive in my fluval fx4 canister filter during a power outage? I have a battery powered bubbler I can split between the filter and 55gal tank.

The power can go out for 30mins to (rarely) 12hrs. Also, will cooler temperatures around 47 kill the filter?

I have those emergency blankets for the Aquarium and a blanket I was going to put over the tank. Will that keep the tank temp high enough.

Your bacteria need to stay wet or they will die. Make sure there is water in the canister filter where the media is. Normally you would put filter media in the fridge, this keeps them good for several days, but 47F is alright.

It’s a lot easier to cool a tank than it is to heat it. Hopefully the blanket will help. If it’s during the day, indirect sunlight can help warm the tank a degree or two.
