Is a Koi Pond Biological Filter Really Necessary?

Okay so in the first part of this article about koi pond biological filter operations we were up to our necks in how these worked. In essence learning that a koi pond biological filter would more properly be called a "bioconverter". Since it converts waste products in the water using what at called nitrobacter bacteria.

Yet you may still not be clear on all this. Prompting this…

Question: What is the benefit of a pond kit biofilter? How is a fish pond biofilter different than a mechanical pond filter?

Okay so that's two questions in one really isn't it? Let's see if we can't handle both.

A biofilter promotes the growth of nitrifying bacteria that eliminates bad stuff in the water that you can't see.. But it's these bacteria that keep the water clean and safe for your fish. Trying looking at a biofilter as simply a "house for good bugs" that keep the water quality high.

While a mechanical filter simply removes the debris you can see.

Question: Do I really need a koi pond biological filter if I have plenty of plants and my water is clear and seems to be good quality?

If you're testing your water and it's okay, no. Some koi ponds can be in balance with one or two fish and plenty of plants. But more than likely if you've got koi you need one as koi tend to be very big dirty fish.

Backyard Ponds Tip: Don't clean your biofilter with chlorinated water. The chlorine can stop the growth of the two good bacteria colonies, particularly nitrobacter, which takes time to develop properly.
