koi pond filter

If you are installing a filter to keep water clean the pond, there will be a standard offering from a mechanical filter and a biological filter. In addition also can use a UV clarifier or sterilizer to help clear cloudy water.

There are biological filters that are similar to mechanical filters and as chemical filters, including vegetables and homemade filters.

So what does all this jargon mean?

Mechanical filters

A mechanical filter to trap dirt and debris and prevent it from contaminating the water in your pond. The simplest type has a screen on the inlet side of the bomb that catches all the dirt. Other more complicated types are more similar to the filters used in pools often using a sand filter to get rid of all dirt.

Mechanical filters are based on different types of media, ranging from foam and mesh screens and brushes, stress, literally, and trap dirt and Gunge. While it is true that mechanical filters tend to clog rather easily, you can also use a mechanical pre-filter between the tank and water pump it will stop large bits of debris and dirt from blocking the system.

A disadvantage of mechanical filters is that in general it will take some time cleaning. But they are generally well priced and therefore affordable.

Biological filters

The main difference between mechanical and biological filters is that the latter are designed with a filter bed containing live bacteria that do the actual work of breaking down substances harmful in the water and its conversion into the stuff that plants can absorb and literally feed.

Biological filters need only be cleaned every four to eight weeks and the process is usually a quick one. In fact, if you clean too much going to kill the bacteria that they valued the work of maintaining your pond water clean and clear.

But there is something you have to remember about the biological filters, and that is the pump that keeps water flowing through the filter needs to be fed all time. If the water does not flow through the filter, it will not work.

Other filters

You will also find a combination filters mechanical-biological and chemical filters that clean water through its distribution (with the help of a pump) through some type of activated carbon as zeolite. And then there are combination chemical-biological filters.

Veggie filters are in the form of small tubes or small ponds that are connected to the garden pond. They are well planted and the plants absorb the excess nutrients from the main lagoon, reducing algae. But if there a lot of plants in the pond itself, this type of DIY filter will not make much difference.

If you are using a reasonably small pond submersible pump, can also make a very efficient pre-filter by the bomb planted in a basket that was half full of pea gravel without sand.

UV clarifiers and sterilisers

UV pond filters , which be used in combination with a mechanical or biological filter, is a relatively high technology. These filter aids are made with an ultraviolet (UV) bulb is in a clear waterproof housing. Then, when the algae, bacteria and viruses in water exposed to UV light, simply die.

ultraviolet light also encourages organic matter to clump together so it is easier for the filter to collect dirt present.
