snip from site: " The ClearPro™ secret is a proprietary, porous tube that water must pass through before re-entering the pool. It creates a final barrier to the very smallest particles that sand cannot trap, including the finest dust particles, algae and pollens. The result is water that’s 60% cleaner than with any other sand filter. Put another way…the best water quality with the most user-friendly, lowest maintenance solution. "
Reminds me of an RO filter but w/o the continuous waste outflow. The passage "holes" are obviously larger too. You must have to open & flush out the tube periodically.
I am interested in buying it too, but would need more info than that! Hope others post what they find out on it...
