The Importance of Proper Filtration in Your Fish Pond

When you have a fish pond, there are many things that you have to play close attention to in order to ensure that your pond is in the right conditions to ensure the well-being of your fish. One of the most important considerations is the filtration system that you have in the pond. As with all other filtration systems, the intention of pond filtration is to ensure that dirty contaminants are kept out of your pools, and that your fishes have only the best and cleanest water to swim in. Having a koi pond at home can be a paradise that you can spend lots of time relaxing near, whether alone or with friends and family, but if there is no proper filtration, it can easily become a nightmare.

Roles of Pond Filtration

Pond filtration serves a variety of purposes. The first of these is mechanical filtration, which involves the removal of fish waste, leaves and other debris from the water in the pond. In the absence of a filter, the debris will quickly begin to deteriorate in the pond, resulting in poor water quality. The poor quality of the water will eventually result in parasitic outbreaks, illness of the fish and, in extreme cases, the death of the koi fish.

Fish PondThe second role that is played by new and more technologically advanced pond filters like Oase Filtoclear is what is referred to as biological filtration. This is why many pond filters are often referred to as bio filters. In this type of filtration, the purpose is to create an environment that is ideal for the nitrification process. This process involves the transformation of ammonia to nitrites, and ultimately to nitrates. Ammonia is toxic to fish, hence the need to change it to something that is safer for them.

Types of Pond Filters

Pressurised filters are very common in ponds. They are very similar to the canister filters that are used in aquariums, and are a very popular choice among people whose ponds or water gardens are smaller. The filters usually have an integrated ultraviolet clarifier which acts to achieve clear water while preventing algae blooms. Some of these systems are also offered with a submersible pump, which is an added convenience for the pond owner.

Sequential filters operate by having water pass through a sequence of chambers, with each chamber featuring a different bio media type. As water cycles through each chamber, debris is removed, biological filtration is achieved, and water is polished on its way back to the pond.

Moving bed filters use floating bio media that stays afloat in the pond water. The media is kept in a chamber that is then connected to an air pump. This air pump is used to push a constant flow of oxygen into the chamber, which keeps the media constantly moving. This oxygen rich environment with high surface area creates a perfect environment for the nitrification process to take place, resulting in excellent water quality.
