Product Information
Full details
Swell's Blanketweed formula is just as good as more expensive alternatives, but gives you more for your money. It's easy to dose - just... Swell Control Blanketweed contains a mixture of friendly bacteria that can help reduce the levels of nutrients that encourage Blanketweed to grow in your garden pond. In addition to being easy to dose and use with no measuring required, this Blanketweed treatment can be simply dropped into your pond or pond filter once a week during spring, summer and autumn. It's also chemical-free, making it safe for wildlife in and around your pond.This Swell Control Blanketweed treatment comes in a twin pack with a total of 12 water-soluble sachets. Each of these sachets treats up to 1,000 gallons/4,546L of pond water. These sachets are made of natural materials and are therefore harmless, so it's safe to add a whole sachet to smaller ponds or use multiple sachets in larger ponds.
