Wait a minute, I'm confused which doesn't take much...

You opened up the lid on the filter which has been sitting full of water for months and the ammonia was 4.0 ppm?

Or the ammonia level in the filter is 4.0 after you hooked up the filter to the tank and after you dosed the tank to 2.5?

Sorry, just trying my best to follow along....

Have fun and be PATIENT!

Yes, I popped the top of a canister that has been sitting full of dirty (seeded) media and water for 4 months and the water at the top was 4 ppm.

I only have an XP3 running on the tank at the moment. I can only assume the ammonia concentration was up in that filter too, as they were unplugged at the same time. I added ammonia to make around 2.5 ppm for the tank, but with what was probably in the filter the overall concentration may be as high as 3 ppm.

Tomorrow night I'll post test results.

90 - Congo tetras, african knife, upside down cats, spotted ctenopoma, kribensis, delhezzi bichir
2.5 - betta

4 months is too long for the canister to sit.

I'm going to give it some more time to see if the ammonia will drop any, but I am not expecting much at this point. So we will see if the bacteria will "wake up".

There's likely too much decaying material in there for you to see it drop any time soon. Perhaps sometime you could test it for nitrites and nitrates?

I might expect that there is either no nitrites as everything is ticking along as it can, or the nitrites may be very high. The ammonia oxidizers will only go dormant in one of three cases:

1- no ammonia to feed on
2- ammonia over 10ppm
3- nitrites high enough to cause them to go dormant... I might think between 1 and 4 ppm to be this threshold but I dont know. Its not something studied as much as ammonia oxidization capacity is.

The ammonia was off the charts when I set up the tank, but now it is 0. Nitrites are also 0. I didn't do a thing to the tank - no water changes or anything.

Looks like 4 months was not too long for the bacteria to sit, but rather 4 days was too short for it to reanimate/make an impact.

Further ammonia dosings and tests conclude that the bacteria has been reanimated - tank is ready for fish....



Stage 2 of the experiment - how long does it take for the bacteria to come back.

I'm going to turn off that filter and add the second canister (thats been sitting) to the tank. Then I'm going to dose the tank with ammonia and *gulp* test every day.
