BettaSafe is a good water conditioner, and you don't have to always use the same kind. If it's working fine, and your fish is fine, then keep using the same water conditioner, and all things being equal, your fish will get better. On the other hand, if your fish is getting worse, just change one thing at a time to help your fish maintain his current state of health. This way, you can start to eliminate possible reasons your fish is sick or figure out which thing it is that is causing him to be sick.
