I have some power outage problem in my area these days. I am using a canister filter with a light bioload. So I'm a bit confused about the survival of the beneficial bacterial colony in my canister media. How long can a canister filter can be in off position in an aquarium without compromising the safety of my fishes? A quick answer would be helpful. Please help guys.

In general, it is safest to keep the canister filter running. If it must be turned off due to a power outage, the filter should be able to remain off for up to 12 hours without significantly impacting the beneficial bacteria colony. If the power outage is expected to last longer than 12 hours, you may want to consider taking steps to ensure the bacteria colony is not compromised. This could include removing some of the filter media and storing it in a bucket of aquarium water, or performing a partial water change to help reduce the amount of ammonia and nitrites in the water.

It's all depends upon how much bioload your aquarium has? In normal case a 12 hour power outage won't be a problem. Even 24 hour can't be problematic if your bioload is very light.
Actually those beneficial bacterias can survive as much time if enough oxygen and ammonia or nitrite is present. They are using dissolved oxygen so you don't need to bother about the canister is open or not. I have seen on many forum sites that canister should be open in order to keep oxygen levels during power outages. It's really nonsense to do so.
Most of the times people are much worried about aerobic bacteria when power failures occur. But the real fact is only a top filter is having such a risk as the media will be dry when the power is off. So nothing to worry there in case of a canister or internal filter.
In my personal experience I haven't got any problem with my canister filter even for 24 hours in my aquarium with medium bioload.
In your case I can guarantee a 8 to 12 hour off time won't be a problem at all.

In general, the canister filter can be turned off for up to 24 hours without endangering the health of the fish in the aquarium. It's important to note that if the power outage lasts longer than 24 hours, you should do a partial water change to replenish the oxygen level in the tank and replace some of the beneficial bacteria that the lack of filtration has caused. have been lost due to
The length of time a canister filter can be turned off in an aquarium depends on several factors, such as the size of the tank, the amount of fish and other inhabitants, and the frequency of water changes. Typically, it is recommended to not turn off the canister filter for more than 24-48 hours, as this can lead to a buildup of harmful chemicals and a decline in water quality. It's important to monitor the water parameters and take appropriate measures to maintain a healthy environment for the aquarium inhabitants.
It should not be off for more than 1/2 day - that too only in the event of power outage. Ideally it should run 24x7. your fish, the microbes in your tank are pretty hardy. Turning off the filter for a night now and then isn't going to hurt them much. But if you do it every night you are depriving your fish and the microbes of oxygen for eight hours out of every twenty-four, and that will eventually catch up with them.
A canister filter in an aquarium should not be off for more than 4-6 hours, as the beneficial bacteria that live in the filter media can start to die off after that time, leading to a decline in water quality. It's important to maintain a consistent and uninterrupted filtration system to ensure the health of the aquarium's inhabitants.

Canister filters can typically be turned off for up to 24 hours without compromising the safety of your fish. However, if the power is off for longer than that, you may need to do a partial water change and add a bacteria supplement to help replenish the beneficial bacteria in the aquarium. Additionally, you should avoid turning off the filter for extended periods of time, as this can cause the beneficial bacteria to die off and can lead to poor water quality.
