I too have a bacquapure "water polishing" system just like yours. My problem is that i do not understand the dial adjustment system. There is a dark blue dial right in front of the chlorinator (aka "polisher") ....is there any way to tell hi from lo? I generally just leave it half way opne, so i know it is at least on "medium". LOL! I also did not know about removing the plastic grid at the bottom of the chlorinator. Thanks for that info. I have been using chlorine since the second summer i had my pool. Bacquacil was awful, and EXPENSIVE too! AND it made my skin itch!
