QUESTION:
What is a good source for additional bio-filtration for my pond? I have a waterfall filter, and a veggie stream. I still think my pond can be clearer and there is a lot of sediment floating in the pond. ANSWER:
A Hydro-pond filter is an excellent source of bio-filtration for a pond. It works a pre-filter for any pump intake and even as a stand alone filter. Sponge filtration is one of the most under rated forms of filtration for ponds and aquariums alike. When used and properly cared for, a sponge filter colonizes aerobic bacteria for ammonia and nitrite removal, and they make excellent mechanical filters, trapping a lot of floating debris. Care is simple; just remove the sponge and squeeze into used pond water to remove the waste. This retains the beneficial bacteria, while removing organic and other waste from clogging the pond or even before going thru the nitrogen cycle. Some of the attributes of sponge filtration for ponds are: *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. * Can be used in vertical or horizontal position. * Easy to clean. Just rinse and squeeze. 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. |
