BactoPlus Fresh PSB

Living photosynthetic bacteria for superior water quality.

Fresh PSB is active immediately after being added to your pond. It improves water quality and clarity by removing ammonia and other impurities from the water. PSB bacteria do not consume any oxygen.

Dosage: Use Fresh PSB at a water temperature above 12°C. For initial use in new ponds, add at least 10 ml per 1000 litres of pond water for 5 days. For initial use in existing (polluted) ponds, add at least 10 ml per 250 litres of pond water for 5 days. For maintenance, add at least 10 ml per 250 to 500 litres of pond water every week, depending on the number and size of the fish. Switch off UV equipment and ozone generators for at least 24 hours after adding PSB. Shake well before use. Store in a frost-free location.
