I don't want to go into detail, but I need some serious help right now.
My friend just lost her betta and I'm losing two of mine, both with similar symptoms. I was told that It's columnaris, and that's understandable.
We believe it's the water on campus and there is something in it. There is so much construction going on and pipes bursting that it's possible.
The ammonia and pH read on normal levels for me (as in what they have for the last year+) which is 0 - 0.25 ammonia and 7.6 pH.
The readings are still the same, but somehow all three fish are catching colunaris. Pudge (my third betta) also had the fuzz symptons, but he was placed in maracyn (to treat something else) and it cured him. However, I wasn't aware of how fast this progressed and now I'm losing my fish.
So, my main question is,
What can we do to make the water safer for the fish for now?
We are contemplating using distilled water and campus water for changes, or even boiling the water. I'm to afraid to do anything with the water and the tanks right now, but she's planning on cleaning it soon.
