Evolution Aqua K+ Moving Bed Filter Media – 50L
K+ media provides the maximum active surface area for bacteria to colonise, more than other types of static media. It is this process which removes harmful ammonia and nitrite from the water. Unlike foam, matting, or other forms of static filtration media, the Kaldnes media is designed to move freely within your filter and the constant chaotic movement of the air from your pump causes the media to self-clean and thus requires no maintenance. This allows the filter to reach optimum effectiveness without the disturbance of periodic cleaning, avoiding unnecessary loss of bacteria within the filter.
K+ Media – What’s New?
With a new shape and profile, K+ media has been designed to have an increased and more efficient surface area for bacterial growth.
| Capacity | Filter Type | Surface Area |
|---|---|---|
| 50L | Moving Bed Filter Media | Maximised active surface area |

Natalie Robertson –
I’ve been using the K+ media in my 50L tank for three months. The water clarity has improved significantly, and I haven’t had to clean the filter at all. It’s easy to install and works well with my pump setup.
Leonard MacDonald –
The media performs better than the foam filter I used before. It stays clean and the ammonia levels have dropped noticeably. I appreciate the no-maintenance aspect.

After switching to K+ media, my tank has been more stable. The bacteria colonies are thriving, and the filter runs smoothly without any clogging issues.
