My aquarium has been established for a few months now and contains a good ammount of large fish. The water is changed at %15 daily, and the gravel is cleaned every three days (due to messy eaters). Water condition is as close to perfect as possible. Though no matter what white spot will get to my fish every month, and this month ive treated it and it still seems to be getting worse with ICH CURE and Aquarium Salt. Why is this happening?
