Shake well before use. Add 50 ml Tetra Pond MediFin for every 1,000 litres of garden pond water and distribute evenly throughout the water

Do not use UV clarifiers, synthetic resin or activated carbon to filter the water during treatment. The treatment cycle lasts from four to seven days and begins as soon as the one-off dosage is administered on the first day. The remedy takes effect during the days that follow. If possible, use activated carbon to filter the water at the end of each treatment cycle. The filter should not be heavily soiled. Tetra recommend providing an additional form of aeration. A second dosage can be added to the pond once the water has been filtered. At least two consecutive treatment cycles are recommended for ponds that have low water temperature and are infected with white spot disease. The use of the treatment as a preventative measure, particularly after a dormancy period and when adding new fish, is also recommended.
