The Aquascape Pond Aerator Replacement Aeration Disc provides your outdoor pond with better circulation than a standard aeration ball by using a disc comprised of weighted air stone. This replacement disc has a four-inch size and will help you maintain proper oxygen levels for your outdoor pond throughout the year.
Why should you choose an Aquascape fountain? Because Aquascape's vision focuses on an ecosystem approach to water features that relies on nature's balance of circulation, filtration, plants, fish, and rocks and gravel to ensure sustainability. They're the leading water garden innovator in North America and the inventors of the low-maintenance ecosystem pond, the number one contractor-installed water garden. Aquascape is committed to the environment, as evidenced by their recent achievement of a silver-level LEED (Leadership in Energy and Environmental Design) certification for its corporate headquarters.
