The Tidal Polishing Pad traps and removes fine particles and debris, polishing water to exceptional clarity. As with all mechanical filtration media, the Tidal Polishing Pad should be cleaned regularly by thoroughly rinsing under clean water. When it no longer rinses clean or has visible signs of wear, it should be replaced.
I have only used it a few days, but they seem to be doing a good job of filtering out the small particles that get through the pre-filter and the course sponge! I'm very happy with my purchase!
