New for 2021! Evolution Aqua's newest line of Evolution Aqua award-winning filtration now comes with K+ Media!

This protected surface area safely houses friendly filter bacteria and prevents them from being flushed to waste during the cleaning cycle. Only dead bacteria, waste debris will be discharged. This results in no Ammonia and Nitrite spikes after maintenance.

The K+ MicroBead filter has been designed to allow an unrestricted flow of water through the unit meaning a lower wattage pump can be used saving you money. That said, in our own testing, we found the following flow rates to offer the best performance in terms of clear water.

Play It Koi recommended pump size for Evolution Aqua MicroBead Filters:

  • K+ Pressure Filter 2400 - 15"D- 1500 gph-2400 gph
  • K+ Pressure Filter 3600 -18"D- 2400 gph-3600 gph
  • K+ Pressure Filter 4800 - 20"D - 3600 gph-4800 gph
  • K+ Pressure Filter 9600 - 24"D - 4800 gph-6000 gph
  • K+ Pressure Filter 14500 - 30"D - 5000 gph-6500 gph
  • K+ Pressure Filter 2400 - 36"D - 5500 gph-7000 gph

The k+ media will work with a wide range of flow rates. Using the lower end to middle of the flow rates below are suggested vs the higher end of the flow rates. The reason for this is because the media works using settlement rather than trapping for mechanical filtration. This is better because it eliminates channeling and is better for biological filtration.


  • Uses K+ filter media for dramatically improved biological filtration compared to using beads
  • Multi-port valve and blower included with all models
  • Blower used during cleaning cycle
  • Large clear viewing lid on top of the filter
  • Improved flow through K+ filter media

MicroBead Filter 24"

I'm so looking forward to having a system to clean just once a week compared to my Savio filter setup which is daily debris basket and filter media cleaning (twice in the summer). I'll let everyone know how the setup goes and most importantly HOW IT WORKS!!!!!

It's like Magic!

I got it installed and it was like Magic! The bond is crystal clear now. I've attached a couple photos too. Thank you for your help. I now have piece of mind that the fish will be ok and the pond is healthy.
