Overview

800g Bermuda Blanketweed Pond Treatment 

Bermuda Blanketweed is a 100% fish, plant and wildlife safe pond additive, and is easy to use. It can be used in ponds and closed water bodies of any size, as often as every 14 days as required. Bermuda Blanketweed does not negatively affect biological filters or bacteria, and UV clarifiers do not need to be turned off during its use.
The addition of Bermuda Blanketweed will cause pond water to turn white and cloudy for up to 5 days, but water will clear. The positive effects of using Bermuda Blanketweed should be seen within 10 days, although dosing can be repeated every 14 days. Store in a cool, dry place, away from children and animals. Wash hands after use and do not ingest or consume. Always ensure the pond is adequately oxygenated via 24 hour per day aeration by filter outlets, fountains, waterfalls or airstones.
