Hey so I've read the chlorine threads and ive been using just dichlor up to now and I just wanted to see if i understand the switching to bleach part..
So dichlor is chlorine+cya, and bleach is only chlorine?
Also if my tub has an ozoator how much free chlorine should I maintain?
And how often should I add x amount of sanitizer? (Asking because I had a problem a while back about not being about to hold chlorine but I fixed it..) Assuming 500 gal tub, use 2-3 times a WK for about 45 min.
