Cloverleaf Pre-vent Blanketweed 800g

Pre-Vent is a unique formula that seeks to succeed where many commercial bacteria cultures fail. Pre-Vent is safe for all pond fish, plants and biological filtration systems. Pre-Vent is to be used every 10-14 days approx to help rebalance your pond. To aid in the prevention of the return of stubborn Blanketweed.

Suggested Dosage:

Add 10g per 266 gallons (1207L). The enclosed scoop can be used 1x scoop = approx 800 gallon (3632L). The dosage can be adjusted as required with no adverse effects. We recommend dosing 10-14 days approx after using Cloverleaf Blanket Answer.
Pre-Vent is to be added to the pond by mixing with sufficient pond water and spread evenly around the entire surface of the pond. The pond will take on a mild cloudy appearance which will usually clear in a few hours.
For best results, use above 10 degrees Celsius water temperature.
If river-type fish are present (sturgeon, orfe, rudd etc), pond saturated oxygen levels need to be maintained at a high level.
