There are three main objectives of a filtration system besides simply removing ammonia and other toxic matter from the fishpond. It should be able to maintain optimal conditions for the continued health of the fish; it should remove the toxins from the water at a rate that is fast enough depending on the size of the fishpond and the number of fish. You also want the water to be always crystal clear to ensure that.
Pump and Flow Rate
The right choice of Koi pond filters is dependent on the Proper flow rate from the pump. For the whole system to work smoothly, you must know how much water will be pumped at any given time. The flow rate of the pump affects filtration because for effective filtration to take place, the water must be held into the filter first before being released back into the fish pond. This means that there should be prefect coordination between the skimmer and the pump.
If you are in the planning stage of the fishpond, you may want to consider the energy costs required by the pump and the skimmer. The bigger the project the bigger equipment you will need. The pump for Koi Ponds should have a flow rate of about half the volume of the fishpond.
Pumps need to have the right diameter of pipe as this can affect the flow rate. The positioning of the pump is also critical in ensuring everything works perfectly. Try as much as possible to position the pump at a level slightly below that of the fishpond.
Types of Filters
There are two main types of Koi pond filters that are commonly used. There is the Gravity flow and there is the pressurized system both are unique and have their own benefits to suit different needs. Gravity flow is suitable for solid waste management and is better than the pressurized one in this respect. It is often favored when there is a need to grow beneficial bacteria. It can be combined with a smaller pump to ensure there is a more effective backwash in the system.
Cleaning and Combining Systems
The filtration system needs to be cleaned often to ensure that the system is working correctly and the Koi remain healthy. In summer, you may be required to clean the system as often as once a week. In winter, the system is cleaned fewer times; around once a month. The best skimmers will use a combination of the two. This reduces the need for cleaning and is a more superior, albeit expensive, system compared to each of those used alone.
There are other filtration systems such as the high end Japanese Bakki Shower. Getting the system right the first time will spare you from a lot of headache. Just like with Koi Pond fiber glassing, it is important to consult a professional before embarking on the project. Koi pond filters are of various kinds; bead filter, trickle, biological and pressurized filters. Choose the one that suits your requirements.
