Economical Sponge Filters or Pre Filters for your Pond or Aquarium Sump. |
 HYDRO-POND FILTER The Hydro Pond Filter utilizes reticulated filter foam for higher flow rates. It provides both mechanical and biological filtration. Aerobic bacteria colonizes the sponge, providing a bacterial substance to facilitate the nitrogen cycle. In addition, the Hydro Pond Filter traps larger waste particles mechanically cleaning the water. (Please click on picture upper right for a larger view of the Hydro Pond IV connected to a pump) ADVANTAGES: • Maintains the biological filtration when main filter is changed or cleaned. • Prevents debris such as dead fish and plant material from clogging the intake by distributing the suction evenly down the length of the sponge. • Prevents small or baby fish from being suctioned into the main filter or water pump. • Can be used as a temporary or permanent filter in ponds. • Traps larger waste particles, mechanically cleaning the water. • Includes adapters for use with various water pump intakes. • Can be used in vertical or horizontal position. • Easy to clean. Just rinse and squeeze. • Fits most water pumps and filters. • The #4 makes an excellent pre-filter (or even primary filter) for sumps in large aquariums! In fact I have used them several times for this application with excellent results • The #4 Hydro Pond filter is also an excellent pre-filter for canister filters especially polishing micron filters such as the Magnum • I have also used the Hydro Pond #2 for large breeding aquarium (over 150 gallons) A simple application would be a Hydro pond filter attached to a Via Aqua 2600 (740 gph) or 3300 pump, then run to a UV sterilizer, then back to the pond via a waterfall or other water feature. This is a simple and cost effective way to set up a pond filtration system. When combined with a veggie filter (water iris or other bog plants with a small current of water passing through the plant roots), you will have an excellent filter system for under $150 that can maintain a pond up to 1500 gallons.
