Oase BioSmart 5000 Gravity Filter

The BioSmart Gravity Filters are a multi-stage mechanical and biological filtration system in a compact package. During biological filtration, the water is channeled through a series of filter foams that create a special environment by allowing the settling of beneficial bacteria. During this stage, harmful ammonia and nitrites are converted to nitrates, which support plant life in the pond. For best results and clear water guarantee, use with an appropriately sized Oase pump and UV clarifier.

• Innovative flow-through filter design provides maximum oxygenation
• High-surface area filter foams provide exceptional biological filtration capability
• Distinct filter zones promote the settlement of a variety of beneficial bacterial responsible for different phases of the nitrogen cycle, which increases the conversion of harmful ammonia in your pond
• Advanced features include the built-in cleaning indicator notifies you when the filter needs cleaned and water temperature display tells you the water temperature at all times
• Cleaning handles for convenient maintenance allow for easy cleaning without needing to remove or manually unclog the filter foams
• The BioSmart 5000 uses the following foams - 2 Blue foams (#40975), 1 Green foam (#40976, 1 Red foam (#40974)

The Oase Clear Water Guarantee is your assurance of clear water down to three feet, a guarantee like no other. Precisely engineered and matched components function in concert to remove not only suspended solids for excellent clarity, but toxic wastes as well, assuring high water quality. Filter pumps designed to pass solids pick up and deliver fish wastes to multistage filters. Filter foams of varying densities strip out solids and particulates. Beneficial bacterial colonies remove ammonia, nitrite and nitrate, eliminating nutrients in the water. Finally, water is bathed in ultraviolet light in an EPA-certified clarifier to further inhibit the growth of algae. You will be able to read the 1" mark on a measuring tape three feet below the surface, guaranteed.
