I have one thread about trying to cycle one 5g tank here
http://www.bettafish.com/showthread.php?t=123144
In efforts to control the ever present ammonia levels, I cleaned EVERYTHING completely - including his jar; bought new gravel. The Betta betta spent the night in his Betta jar (floating in the tank), to ensure the gravel was well enough filtered. All new water of course; and tested the tap water again to ensure that ammonia is still 0 there.
Today, I got him out and tested the water in both the tank, and in the jar with the fish. The jar looked totally clean ... no poop, etc. But the ammonia level was at 1.0! I realize the jar is rather small, but would one expect the ammonia to spike that high overnight - especially since there was no dirt, etc?
I'm beginning to wonder if perhaps there is something abnormal with this fish, that is causing the problems with cycling?
Again, I've kept fish for at least 20 yrs, and am very familiar with the cycling process; and until now, have never had any trouble successfully completing a cycle.
Thx
