ok added more cya to sock...no more than 18 ounces will fit though so added that much and will add more as it dissolves into the water. Just rechecked pool again -- pH 7.8, TC about 4 (tough with the yellow color matching) and Free chlorine on stick 0 (again i have dip sticks only to see if I can get ANY free chlorine in this pool!)
also, when should I backwash filter? and can i do it into grass or will chlorine kill it?
