When in doubt,, performing a 30 to 50 percent water change with fresh dechlorinated water that is close to same temp as the tank can never hurt. Perhaps these water changes would need to be once each day for a week.Before I began dumping medications in my tank ,I would want to test the water with test kit, or take sample of my water to local fish store and see if they would test it for me. I would take the sample of water to be tested BEFORE I performed water change.
I would want to see zero for ammonia and nitrites, and nitrates somewhere between 10 ppm and 40 ppm between weekly water changes of 30 to 50 percent.
