My male betta has fin rot and is in a 10 gallon tank. The ammonia level has been a 0.25ppm for a while now and I can't seem to lower it. My tap water has 1ppm ammonia in it, so water changes just make the condition in my tank worse. Because my tank is not cycled, something like prime won't help much because the ammonium will just convert back in 24 hours.
I got some ammo chips about a week ago and put them into both of my betta tanks. The ammonia in my female betta's tank went down to 0 very quickly, but the ammonia in my male's 10 gallon stayed the same. I think this is because a few weeks ago I added 2tsp of salt to his water to help with his fin rot. I have done a 50% and several 25% water changes since then so I figured the salt levels in the tank would not be enough to affect the ammo chips which don't work in salt water. It wasn't enough though and the ammo chips aren't helping with the ammonia.
Should I do 100% water change to remove all of the salt from the water? It would be a lot of work, and it would be stressful for my betta. I'm also worried it might also harm any cycle that might be starting in my 10 gallon. What should I do?
