| I have one (Adv 10 bead only), know several others that do. IMHO, the best bead filter you can buy. Very happy with mine. In normal operation mine is sitting behind a ~225gal Vortex, and 55gal Microstrainer (250 micron), then pump to Bead filter - Shower Filter. I think your compairson is odd, are you saying a Vortex, then 2 more vortexs with static filter media? Just mechanical or Bio? |
