I had a sick betta with velvet and fin rot and he is just about all better (it took several weeks). Meanwhile, I bought him a bigger tank, 5.5 gallon and cycled it. It has been sitting for about 3 weeks. I've been adding some fresh water as I don't have a cover and it evaporates. But, this past week I didn't test it, got busy. I did add a gallon of water, though.
Meanwhile, I had to let a couple extra weeks go by because Betta was still showing signs of sickness. Now I want to put him in his new home and here are my readings:
Nitrates-was between 40 and 80 ppm
So I added some Seachem Prime and now the readings are:
Ammonia-just about .25ppm
Nitrates-seems to be close to 40ppm
I think I did something wrong. Any suggestions, advice?
