So, in trying to get rid of a HUGE algae problem on this years opening, I have totally messed up my CYA. Over the 6 years I've had my pool, my CYA has been rising every year, and I never knew why until I found this site last weekend. This year, after putting in 20 gallons of liquid chlorine to shock the pool, I also turned my chlorinator up high, to keep "shock level" until the algae cleared. After 2 weeks, it hasn't cleared, and my chlorinator has dumped in 40 pounds of DiChlor in the last 2 weeks.
Now, my CYA is about 200, my FC is so high nobody can read it, and I am in the process of a drain to try and get things under control. But, I've searched the forums and pool school, and found that DiChlor is a culprit for continued raising of CYA. So, when I get things fixed this year, I want to stop that. So, hear is "finally" my question.
I have a Polaris G-1000 watermatic chlorinator. It says to use only DiChlor in it. I love this automatic chlorinator, as it monitors PH and FC level all the time, and adds accordingly. It holds 10 pounds of DiChlor at a time, and makes for easy, trouble-free work of adding Chlorine. But, now I don't want to use DiChlor any more. What else can I put in this unit, besides DiChlor? Or, will I need a new Chlorinator to get rid of using DiChlor? If I need a new one, are there good automatic chlorinators that use liquid chlorine, so my lazy you-know-what can just fill every few weeks like I do now?
