Anyone know for sure, how long good bacteria will survive in my canister filter without moving water?

tetratech,

I don’t think anyone would know for sure. What I have read was that bacteria start to die after only one hour. This was one downside that was mentioned for canister filters.

The problem here is the lack of oxygenation. The canister is an enclosed entity with no air reaching it directly. How about this: take the media that contains your bacteria out of the canister and place it in a bucket that you fill with tank water. If you have it, hang an air bubbler into the bucket for additional oxygenation. I don’t know if this works, but I for sure would assume it cannot harm either.

In retrospect I should have done that, but now they've been sitting in my cansiter all nite.

EDIT: Interesting The eco-complete bag states that it
"contains LIVE heterophic bacteria to rapidly convert fish waste into natural food for your aquatic plants."

Sorry never took bacteria 101, buy how do these live in a sealed bag for who knows how long.

they live in a dormant state, don't ask me how, thats just what the promo material says.

I usually say 20-40 mins before the cannister starts to smell dodgy.

Ugh! Than at this point since they've been sitting there overnite, I guess I should just clean and rinse the filter eheim efisubstrate

I have always been told about 30min to one hour

That is why when I do a monthly canister filter maintenance nothing stops me. I have every thing ready.

I usually drain three buckets out first and use this to rinse and keep the rinsed filter material in their holders ready for assembly all this taks very close to 30min

I also add 30ml of Bio starter into the canister before I seal it up. After it all connected I complete the water change with the filtration going.
