COLOMBO FRESH PSB 2000 ML
Photo Synthetic Bacteria for superior water quality
Fresh PSB goes to work 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, so they can be used at very high dosage levels.
Dosing
Use at a water temperature above 12c
For initial use in new ponds, add at least 10ml per 1000 litres of pond water for 5 days (2 litres = 5 x 40,000 litres)
For initial use on exsisting (polluted) ponds, add at least 10ml per 250 litres of pond water for 5 days (2 litres = 10,000 litres)
For maintainance dosing, add at least 10ml per 250-500 litres of pond water every week, depending on the number and size of the fish
Fresh PSB goes to work immediately. The higher the dose, the better the effect (overdosing is not possible). It is important to swich of uv equipment and ozone generators for at least 24hrs after adding PSB. Shake well before use. Store in a frost-free, well-lit location to keep the bacteria alive.
