Chemical and UV Filters

When you look into purchasing pond filters, you will be looking at four specific filtration types: Mechanical, biological, chemical and UV.

This article focuses on the last two types of pond filters.

Chemical Pond Filters
When you are dealing with chemical pond filters, you are looking at a filter media that purifies the pond water by chemically binding harmful chemicals in it to the filter itself. When you utilize these types of pond filters, you are effectively removing harmful items from the water, like chlorine, heavy metals, ammonia, pesticides and other unwanted chemical impurities. Having chemical pond filters will help to keep the pond water clear and remove much of the odor normally associated with ponds.

Chemical pond filters absorbs the above chemicals through the use of activated carbon. You can even clean that carbon in salt water for use again and again. Make sure to take out your chemical pond filter for cleaning, however, because adding salt water to your pond can actually release ammonia.

Some pond owners do not use chemical pond filters if they are already using a large enough biological filter (see part I of this article). Those pond owners that choose to use both together do get pond water that is virtually harmful chemical free, though. You may also choose to use a chemical pond filter until a biological filter matures.

UV Pond Filters
Ultraviolet radiation is what these types of pond filters use to kill harmful items. Pathogens, fungi and algae can be eliminated from a pond by using UV. pond filters. An UV. pond filter can also help minimize ICH and fungi in your pond that can cause diseases in the fish you stock in your pond. It is normally best to use UV. pond filters in addition to other types of pond filters, as they are not as effective at removing string algae, blue-green algae and larger parasites.

When creating your outdoor water area, using a variety of the pond filters available will lead to the cleanest and healthiest pond possible.
