Somehow my filters been off over night from 7pm to 7am lucky for the air pump. I assume my bacterias dead, we have a spare cannister running partly for this type of thing. New cycled media, lots of waterchanges and double doses of prime???

I've often left filters off overnight (or thanks to another Perth blackout had filters off) with no issues.

My thought would be it is fine as long as no smell when starting up.

I have shut a canister down for 4 or 5 days and that did have a rotten egg smell on restarting. Well and truly gone anaerobic. Cleaned out filter.

In the reading I've seen the bacteria will survive for weeks if not months without food. The lack of oxygen would be more of a concern.

just be careful when you restart  the canister put a bucket under the outlet as it blow out all the loose shi...  in the pipes etc  plus you can have a smell of it

yeah what dicky said

brown crud in the pipes can blow in to the tank and wouldn't be too good for the health of your tank, not to mention the look

I had a canisted filter unplugged for a few days once, and when I plugged it back in (didn't realise) it blew all the muck in to the tank. Tank looked pretty ordinary for a day. I'm glad the tank didn't have many fish in it, as well as running a second canister filter on the tank which was already seeded

Doesnt smell but Nitrite was nearly off the chart. Double doses of prime, have put the aqua one 1200 on aswell. 1 waterchange per day and I should keep on top of it.

Interesting! What was ammonia (as the nitrite has to come from somewhere) out of interest?

About 0.25 maybe even a little higher. Test results on my aquascaping journal

Thought it would be higher. Will dig back and see if I can find a thread and see if any bacteria are more sensitive.

I'll see if I get a chance to do a nitrite test tonight. Probably too late but I did clean one canister (of two) on Friday night and it didn't get switched back on until Saturday arvo. Ammonia Sunday night was 0 (as was tap for comparison).
