NT Labs Barley Straw Bio Bags Twin Pack
Barley Straw Bio Bags from NT Labs provide a simple and effective natural solution for controlling algae and blanket weed in garden ponds. Supplied in convenient ready-to-use mesh bags, they can be placed directly into the pond, filter, or waterfall area where water flow will help activate their effects. As the barley straw gradually decomposes, it releases natural compounds that inhibit algae growth, helping to create a clearer and healthier pond environment within a few weeks.
These bio bags are suitable for use in both natural and filtered ponds. The treatment is completely pesticide-free, making it safe for fish, plants, and wildlife. Each bag works over an extended period and should be replaced every 6 months for continuous control. For best results, allow approximately 28 days for the treatment to become fully effective.
