Why Choose K+ Media Sinking Wheel
The sinking wheel design allows even water distribution and contact for biofilm growth, creating “quiet zones” where beneficial bacteria flourish. This results in improved nitrification, stable water quality, and reduced maintenance.
Available in bulk packs, the K+ Media Sinking Wheel is ideal for industrial and commercial-scale aquaculture projects requiring reliable, long-lasting biological filtration.
