Many fish disease are encouraged because the fish are under stress and one of the main causes of stress is an unsuitable pH. For ponds the ideal pH, which is a measure of acidity and alkalinity is between 7.0 (neutral) and 8.0 (slightly alkaline) but pH 6.5 - 8.5 is acceptable. Blagdon pH adjusters are uniquely formulated so that even if an excess of adjuster is added to the pond, the pH will not fall outside the safe limits for fish. pH adjuster for Alkaline ponds will safely change your ponds pH from an unsafe pH of 8.5 or above to a safe pH of between 6.5 and 8.5. A course of more than one dose may be required to achieve the safe change in pH. Totally safe for use with all species of pond fish. Typically treats 5675 Litres (1250 gallons)
