NT Labs Barley Straw Stoppers - Natural Pond Clarifier
Description
NT Labs Barley Straw Stoppers are a natural and effective solution for keeping pond water clear. These handy, mess-free pouches harness the power of barley straw decomposition, which releases natural compounds that inhibit green water and algae growth. Ideal for all types of garden ponds, including wildlife and ornamental fish ponds, they provide long-lasting clarity without the need for harsh chemicals.
With a slow-release action, each pouch works gently over time to support a healthy and balanced aquatic environment. Simply place the pouch in your pond filter or directly into the water, and let nature do the rest.
