The natural solution


Evolution Aqua Blanketweed is 100% fish, plant and wildlife safe and using it won't negatively affect any beneficial bacteria or biological filters. It can be used in any ornamental ponds or closed bodies of freshwater and UV clarifiers do not need to be turned off when using it. An all-natural product, the addition of Blanketweed will turn pond water white and cloudy for up to five days, but water will clear. Blanketweed is most effective in ponds with moving water, from a pump, filter, fountain or waterfall, and strong surface agitation, or aeration from an airpump and airstone is recommended.
