Why You Should Use A Biological Pond Filter To Improve Water Quality

A biological pond filter that is of a high quality is able to clean ponds to promote healthier waters from the molecular level. It resembles that of the cleaning system in the natural setting of a river. Bacteria in a river group together on pebbles at the bottom most part of the stream. Toxins are then broken down while the water continues flowing above. This is the natural setting which biological pond filters try to emulate by producing a system where bacteria colonize at different filter layers that are housed outside the pond itself. The water flows through the layers of filter past a pump.

Is a Biological Filter Necessary?

A biological pond filter can easily transform harmful ammonia that is naturally produced by fish waste and decay matters in the pond into nitrite and nitrate. Nitrate is non-toxic to koi and other types of fishes in the pond but it is a nutrient for plants that helps promote algae growth. Hence, it is advisable to control your pond’s overall nitrate levels. How do you handle high nitrate levels? You could first try using a vegetable filter which is a simple additional area around the pond that is laid out with plants that love moisture and can help with natural nitrate absorption. You can also try scheduling partial water changes that replace a percentage of the water inside the pond with new water that is free from nitrate.

Additional Add-Ons to a Biological Filter

• Pressurized filters help solve the problem of how the biological filter needs to be above the pond surface. With a pressurized filter in place, the water will then be pumped into the input channel similarly to the setup of a gravity return filter.
• Gravity fed filters are basically fed by gravity through a drain at the bottom most section of the pond. The last chamber contains a pump that can be submerged which helps to pump filtered water into the pond.

Other Filtration Methods

Though biological pond filters make a good alternative that is more natural, you can still consider various other filtration methods in the market which have their own pros for your pond. List out all the comparison factors that you are able to get from online sites to help you derive with the perfect filtration method for your pond. Many pond owners have considered the Evolution Aqua Eazy Pod which has received nothing but positive reviews thus far. It could work out for you and your pond as well depending on your personal preferences of a pond setting.
