Just got our power back after about 10 hours without - how bad is this likely to be for the bacteria in my filters? I used battery operated aerators in the tanks to keep oxygen levels up during the outage, and I floated the filter media in the tanks with HOB filters, but there was no way that I was messing around with the canister filter in the dark.

My plan is to check ammonia & nitrite levels tonight & tomorrow morning - if things look good by then, do you think I'm out of the woods?

Thanks!
Lisa

The HOB filters should be fine. The canister could be a problem and I would have set it up on a bucket of dechlorinated water before switching it back on in the tank.
There will have been some bacterial die off so a media rinse in tank water ASAP is a good idea.
Expect an ammonia spike and be ready with water changes. This is one time that zeolite has a use.

Well, so far so good - ammonia & nitrites still at zero in all 4 tanks. I've been holding off on feeding, but will give a light feeding this morning. Do you think enough time has passed that I should be OK, or should I keep up the twice a day testing?

Well, almost a week later & no ammonia spike. No fish or shrimp deaths (although the leaves of a few crypts melted - maybe just a coincidence?). Even the tank with the canister filter had no issues. I'm going to count myself lucky & move on. However, I am going to look into some battery backup systems that can power the filters & heaters before winter hits! Smile
