When it comes to selecting an effective biological medium it doesn’t get much better than K1 Media. This can be used as an affective method of trapping suspended solids in a filter without the risk of blockage. But it is when K1 is used as a mobile biological bed that it really comes into its own. With next to neutral buoyancy it is easy to keep this media in constant motion with the use of air. By so doing it becomes self-cleaning with next to no maintenance. It also ensures that every part of the media has a constant flow of well-oxygenated water that is so essential for maximum breakdown of the fish ammonia.
- Large Protected Surface Area
- Used with Nexus and Eazy Pod filters
- Ideal for use in moving bed filter systems
- Can also be used in box, pressure and multi-bay filters
- Increases the efficiency of a filter
What is K1?
K1 is a small, wheel shaped plastic media used in pond filters to trap suspended solids and promote the growth of beneficial bacteria. These micro-organisms convert toxic ammonia produced by the fish into less toxic nitrate, and ultimately nitrate, through the nitrification process. A key feature of this media is that it has a fantastic protected surface area which greatly aids the development of these bacteria.
In the centre of the wheel is a protected surface that allows the growth of a secure biofilm that is able to resist collisions when operated as a moving bed.
Why is it important?
Maintaining excellent water quality lies at the heart of maintaining all aquatic life whether it is in an aquarium , garden pond on natural lake. It is often said that we are not keepers of fish but maintainers of water quality. When water quality deteriorates the health of all aquatic life suffers and can lead to fish disease and, ultimately, an untimely death.
How to use K1 and K1 micro
K1 media can be used in two fundamentally different ways.
1) As a static bed.
In this mode the filter is used mainly to trap suspended solids. These solids need to be completely removed from the pond, or fish tank, on a regular basis. This is easily achieved by expanding the media bed with air and running the resultant ‘soup’ to waste. The filter therefore should not be packed tightly with filter media.There should be at least 15% space available for the bed to expand.
2) As a mobile bed.
This is really when K1 and K1 micro comes into its own. The huge protected surface area of the media comes completely in contact with the waste and plenty of oxygen. The constant collisions prevent the accumulation of solids provided there is sufficient space for the media to become fully fluidised.
For the media to move it needs to be ‘conditioned’ in the filter for a few days in order for it to achieve neutral buoyancy. Initially it will float high in the filter and not flow easily. It’s only a matter of a day or two before everything operates in the way it should.
Alternative Filter Media
It is easy for nitrifying bacteria to colonise virtually any surface so there is a huge range of alternative media for this aspect of water purification. Similarly there is a large number of different media for trapping suspended solids. What defines all these media is primarily their abilities to be cleaned. Sooner or later they will all get clogged up and cease to be affective. The beauty of K1 media lies with its ability to be easily cleaned and resistant to clogging. Due to its neutral buoyancy a small amount of air injected into a filter will cause the bed to move, thus separating the excess solids from the media surface area. The solids can then be run to waste. In this way the effective surface area remains as high as possible.
