Contrary to popular belief, biological filters do not process or filter the solid waste of fish in the koi pond. They continue to build and rot, creating a breeding ground for harmful species of heterotrophic bacteria that are pathogenic to koi fish. As indicated, biological filtration process utilizes Nitrosomonas bacteria to break down ammonia into nitrite, and Nitrobacter, further converting nitrites into nitrates, which is less harmful to koi fish.
plants are now using the nitrate and phosphate for fertilizer, and if you have not given an adequate ratio of water plants for koi fish, "says" algae (growing on rocks and koi pond walls) and "free floating" algae to use nitrate and phosphate to reproduciraju.Ključ to prevent this condition, called "algae bloom" is to provide enough nonsoil bearing plants like water lettuce and hyacinths to compete for nitrate and phosphate. Since these two plants are tropical and can only survive in warm climates, hardier varieties such as Elodea and Anacharis will perform well in cold climates. These plants are commonly used in bio-filter ponds.
bio-filter pond is used in conjunction with shallow ponds with small populations of koi Koi fish. It will also eliminate the need for mechanical bio-filter and pump else rade.Bio-filter pond is larger than the main pond for two reasons. This prevents the Koi fish from eating the plants and provides water from the waterfall that is filtered as it passes through the plant before spilling into the bottom koi pond.
an adequate proportion of plant cover for the koi pond's surface is about 20 to 30 percent. This is a basic rule and that many factors could change that equation. For example: Koi fish populations, water temperature, and the remaining pile of leaves or over-feeding the Koi fish. I've said many times that Koi Koi pond is a living room, dining room and WC.
Please invest in the health of your fish. Buying koi pond test kit from any pet store or a pond. Invest the time to read the directions and begin regular testing of your Koi pond. Remember, pure water does not clean! As the water we drink, just because water looks clean, smells good and tastes good does not mean it is clean.
Most of the most toxic, cancer-causing priority pollutants listed by EPA as a colorless, odorless, and tasteless. Never forget a simple fact: You have a toilet in a separate room of your house. Your scaly friends living their toilet, and they have to swim in it. Keep it washed and cleaned.
prevention is worth a pound of cure pond. DH
If you do not have a bio-filter, which could explain why your koi pond is a tad green, smelly, or cloudy, and why finned family gulping air at the surface. Trust me. It will not be long. Fish gulping air for survival will be like you - in an attempt to avoid breathing toxic air -. Gulping water to survive
