I have a cartridge filter and a chlorinator. I read in the "Definitions & Abbreviations" section that trichlor isn't a 'good choice' for cartridge filters & extended swim season pools (I live in north Texas). Is there a better product I can use in my chlorinator or will the tabs/sticks be ok? I read about liquid chlorine being pour directly into the pool, but haven't come across it being added via chlorinator. Any suggestions? Thanks.
