Things You'll Need
- Ick treatment
- Gravel vacuum
Instructions
Remove the carbon filter from the tank. The carbon filter will filter out the chemical treatment.
Change about 25 percent of the water in the tank. When changing the water, vacuum the gravel well to physically remove the ick cysts. Repeat this step about every four days until all visible signs of ick are gone.
Put the chemical ick treatment into the tank. Follow the label instructions for how much and how often to use. There are several chemical ick treatments available at most any pet store that sells fish.
Increase the water temperature to 82 to 86 degrees F. Keep the water temperature higher during the entire course of treatment.
