Thanks to all for chiming in. I've been on the liquid chlorine now for weeks...no more tablets...it has been VERY hard to keep the my chlorine at 7-9 where i should be for my cya level of 70-80...one problem seems to be the liquid chlorine needs to be very new to work well. In Houston, Tx and it's been in the 90's for a while now...so I'm using a lot of liquid chlorine everyday and it's hard to keep up the chlorine level up where it should be...10% strength ....my plan is to just keep managing it this summer...so far so good...no algae and pool looks great....this winter, my plan is to slowly replace water with new water over several months to lower my CYA....then next summer, it won't take me near as much liquid chlorine each day
