There are several ways to treat Ich, but the most common and effective method is to use a copper-based medication. Copper is toxic to Ich, but it is also toxic to fish, so it is important to follow the directions on the medication carefully.
Here are the steps on how to treat Ich with copper-based medication:
1. Remove any invertebrates from the tank. Copper is toxic to invertebrates, so it is important to remove any shrimp, snails, or other invertebrates from the tank before starting treatment.
2. Increase the tank temperature to 82-86 degrees Fahrenheit. This will help to speed up the Ich's life cycle and make it more susceptible to treatment.
3. Add the copper-based medication to the tank according to the directions on the package. Be sure to follow the directions carefully, as too much copper can be harmful to fish.
4. Treat the tank for the recommended amount of time. This is usually 10-14 days.
5. Monitor the fish for signs of improvement. The white spots should start to disappear within a few days of starting treatment. If the spots do not disappear, or if the fish show any signs of distress, discontinue treatment and consult with a veterinarian.
6. Once the Ich has been eradicated, perform a 50% water change and add carbon to the filter to remove any residual copper.
It is important to note that Ich is a highly contagious disease, so it is important to take steps to prevent it from spreading to other fish. This includes quarantining new fish before adding them to the main tank, and disinfecting any nets or equipment that has been used in an infected tank.
