Certain sizes of Blanketweed Klear are vacuum-sealed during production and all the air is removed from the packet. As such, upon delivery, the product can feel solid. However, once the packet has been opened and air introduced, the product will loosen up to a powder again.

Key Ingredients

Hydrogen Peroxide

Hydrogen peroxide is a powerful compound created by combining hydrogen and oxygen. When applied to algae in water, it effectively disrupts cell membranes and interferes with their structure, causing the algae to break apart and die.
Bacteria

Our range of Bacillus bacteria are versatile and capable of performing a variety of essential tasks, just as they do in nature. Whether it's breaking down waste or fixing nitrogen in the soil, these bacteria thrive in both aerobic and anaerobic conditions, even at low temperatures, to deliver the results you need.
