Cycle experiment

Now that the 125 is full of water, I'm going to hook up the filters. They have been full of seeded media and water since I sold the 75 about 4 months ago. Soooooo, the big question..... is the bacteria still alive. I've left filters off but full of water for nearly 2 months before and still had the cycle. We will see..... ammonia dosing to commence tomorrow.

125 - BGK, chanchito cichlid, pictus cats, silver dollars, palmas bichir
125 - cichlids (severums, bolivian rams, chocolate), rainbows ( turquoise, red), loaches (angelicus, zebra, kuhli and horseface), plecos (BN, RL and clown), denison barbs, tiretrack eel, pearl gouramis, betta
90 - Congo tetras, african knife, upside down cats, spotted ctenopoma, kribensis, delhezzi bichir
2.5 - betta

I'm interested in the outcome of this experiment....

Maybe you could add a poll before you post results, it'd be interesting to see what posters think.

I'd say the bacteria is no longer alive.

Have fun and be PATIENT!

With no source of ammonia for the past 4 months for food, my guess would be that the bacteria is not alive anymore. We shall see :)

Please let us know what happens!! My filters have been sitting in my old fish tank (with rotting plant matter a bit), and not running, so I'm in a similar boat!! :)

Ask and you shall receive - a poll!

There's plenty of decomposing matter in the filter, so I wouldn't exactly say that there is no source of ammonia. 4 months is a pretty long time though.

I voted other. My gut is that some will have survived, but not all, and that it will cycle much quicker than it normally takes.

Being in the same position as you, I just tested my water. I have one platy now I get 4 days ago. I have I think 0 ammonia (hard for me to tell for the test. I couldn't find my card. But color was the same as clean water), 0 nitrites, and 12.5 nitrate. :D so I think you may have similar results :D

Other.

The cycle in the filter will be fine. It takes a long time for decomposing matter to completely decompose to the point of not creating ammonia. Even without the ammonia, the nitrifying organisms go dormant rather than just dying off. How effective the filter only organisms will be seeing as the tank and contents are fresh depends completely on how much of the total ammonia load it was handling previously and how much of a load the decomposing matter in the filter is producing now and how much of a load will be expected with the new tank.

I'd be curious to test the filter water before hooking the filters up to see what the levels are.

Tested ammonia in one of the filters - from the very top of the filter. Ammonia is sky high - perhaps 4 ppm. I'd like to test the water at the bottom of the filter....

I dosed the 125 with about 2.5 ppm ammonia. We shall see what tomorrow brings.
