I have a 45 gallon tank they have been sick for about two weeks now they are all better after the treatment I checked my ammonia was .25 before and now its is all most 2.0 what should I do I put ammonia tablets in the tank and took the carbon out of my aquaclear and put in ammonia remover pad and they are tropical fish

Sorry you haven't gotten an answer yet, but hang in there, our fish expert comes and goes. Have you spoken to anyone at a fish store or a pet store?

Do they have bubbles on their fins? Clear bubbles can indicate a disease called ICK. It can be treated by medication you can buy at a pet store.

Tests will still show high levels after you treat for ammonia. You should do a 25% water change if the ammonia is still high, but make sure you use a declor product on the tap water. What is the nitrite level?

Hope this helps

What did they have and what treatment did you use?
