For those of us who are looking to spend more time enjoying our Koi and less time managing our water - check out this filter from Nexus. I really like the automated cleaning feature. It's on my wish list! 

Nexus 2200 / 3200

I watched this video from Quality Nishikigoi and he talked about his experience Cleaning Nexus 320 Pond Filter, Automatically and Manually, CLEANING K1 MICRO BEAD!!
