I'm a fairly new pool owner. I've been using trichlor the last year but I adjust chlorine levels with liquid chlorine. Usually the 10% stuff.
So I am going to stop using trichlor because it's raising my CYA. I have a sand filter so I do backwash often so over a little time, I should be able to lower the CYA from 65 to a more manageable 40 or so.
Should I add liquid chlorine in the morning or the evening or both? Is there a better time do add chlorine??? How fast does it dissipate?
