Evolution Aqua K+ Advanced Filters are large bead filters. They contain lots of K+ beads, shaped to offer maximum surface area and designed to harbour the bacterial colonies necessary to perform biological filtration. This range operates at high pressure (a maximum of 1.5bar) to further increase the rate of both biological and mechanical filtration.

  • 4 different models to choose from
  • High power biological and mechanical filtration
  • Removes ammonia and nitrate from water
  • Great for large pond
  • Easy to maintain

What are the benefits of Evolution Aqua K+ Advanced Filters?

Evolution Aqua K+ Advanced Filters can process huge amounts of water on both a mechanical level, removing any solid waste, and a biological level, removing toxins like ammonia and nitrate from the water. They are perfect for maintaining large ponds as they require little upkeep and only a low powered pump, and is a great choice with a varipump to allow a better control over the flow and to get the very best out of your filter, as well as reducing the wattage over a fixed rate pump. With an Evolution Aqua K+ Advanced Filter, you can ensure your water is safe and clear for your pondlife.

What is biological filtration?

Biological filtration is the process of using bacteria to remove toxins from the water and replace them with helpful chemicals. Many forms of bacteria are capable of ingesting Ammonia and Nitrates, which are harmful to fish and other pondlife.

What is K+ Media?

K+ Media is an innovative type of media used within the K+ Advanced Filters designed by Evolution Aqua. The Media offers the most surface area possible as well as mechanical filtration and it's formed from a mixture of minerals and enzymes that encourage the growth of helpful bacterial colonies. Using K+ Media you can filter water faster and more effectively than with regular filter media. K+ Media has great benefits, including it's ability to filter particles down to one micron, and has been specifically designed to help improve flow. The K+ media has a large surface area and maintains stable bio-films, as well as being unique in having minerals and enzymes added during manufacture, which makes it mature a lot faster than average. The K+ media has also been tested to verify it's performance by IFTS and Cranfield University.
