They beautify the waterscape with unique structure. You can anchor them in place, let them float freely or link up multiple islands to create your own archipelago!
The plant roots and extensive surface area of the island is colonized by microbes that absorb great quantities of nutrients and pollutants from the water, significantly improving water quality.
The islands and the plants that grow on them provide terrific habitat for most types of aquatic organisms by providing cover and enhancing the food chain. For example, microbes grow on the islands, zooplankton feed on the microbes, insects feed on the zooplankton, fish feed on the insects, et cetera.
Perhaps the greatest benefit is shelter for the fish. Koi & Goldfish relish the shade and protection from predators.

Each island comes with multiple individual planting pockets for plugs and is compatible with most types of terrestrial and aquatic plants. Also included is an appropriate volume of BioMix Planting Media, Installation Instructions and a Maintenance Guide. Custom seed mixes and Island Attachment Systems that link together multiple islands are also available, but sold separately. New 5 year warranty!

This 4.5 square foot Island has maximum dimensions of 22.5"x31.5"x5.5". It provides Biological Filtration benefits for ponds up to 1,000 gallons.
