Things You'll Need
- Thermostat
- Malachite green
Instructions
Remove any filters with activated charcoal and disable UV sterilizers and protein skimmers to ensure the treatment will work properly. Remove any snails and aquarium plants that may be sensitive to the chemical treatment.
To speed up the life cycle of the parasites--as they can only be treated during the free swimming phase--increase the water temperature a 1/2 degree Celsius every day you treat the aquarium. Install a thermostat to accomplish this. Increase the temperature to a maximum of 77 degrees Fahrenheit, or 25 degrees Celsius.
Treat the water with a liquid treatment containing malachite green, such as Quick Cure. Add one drop of Quick Cure per gallon of water daily for three days. If the white spots don't disappear in the first three days, perform a 25 percent water change in the aquarium before adding another dose. For malachite green preparations other than Quick Cure, follow the product instructions for specific treatment instructions.
