Cloudy, dirty water and strong algae growth are common problems in ponds. These problems are caused by floating particles due to an excessive supply of nutrients, dead plants, over-fertilized soil, acid rain, fish excrement and left-over food. These particles produce ammonia which is harmful to all living beings. OASE's unique Biotec Filter System transforms ammonia into nitrite using a natural process. The nitrite is then changed into harmless nitrate. Nitrate actually constitutes a healthy nutrient conducive to plant growth. The mechanical filtration process is carried out by various structured foam filters, the biological process through naturally occurring bacteria that settle on bio-elements. This filter will not eliminate blanket weed (string algae). Not for use in swimming pools or salt water. Another unique feature of the Biotec Screenmatic Filter System is ideal for large particulate removal. Special tool (included) allows for filter sponge cleaning without removal from the filer. Screenmatic surface is automatically flushed as screen rotates debris are rinsed away.

Keeping the pond floor clean and free of unsightly floor sediment, sludge, and plant debris is necessary and, unfortunately, it is often quite tiresome. With the NEW - OASE Pondovac 4 this is no longer the case. The desire at OASE is that pond owners can handle the necessary pond chores as quickly and easily as possible. VACUUM THE POND CLEAN - NON-STOP This is the newest generation of OASE Pond Vacuums which allows the pond to be vacuumed continuously. This is accomplished by means of the two-chamber system. Two identically sized cylinders are filled and emptied in alternating cycles. If one container is full, a valve is mechanically activated by a float. This triggers emptying of one chamber while the other is being filled. This allows pond vacuuming and emptying of the container to occur at the the same time. The result is a product that pond owners will love. It saves precious time, facilitates pond cleaning and guarantees a perfect result. The OASE Pondovac 4 can remove dirt particles up to 3/8" in diameter, such as algae, silt, dead plants and leaves. The debris that is collected can be spread directly over the garden as fertilizer for plants through the discharge hose. An integrated check valve prevents sludge from returning to the pond. Unique two-chamber system allows pond to be vacuumed continuously Built-in wheels allow for easy movement and transportation Includes a special string algae nozzle, a wide nozzle with a rubber tip, a crevice tool and a floor nozzle Includes a vacuum tube extension, as well as a debris collection bag for the water return Ideally suited for wet vacuum applications in the household
