Am a little confused...in pool school, it says if pool is exposed to lots of direct sunlight, CYA should be 60-80, whereas everywhere else its at 30-50...can someone help clarify?
Also, opening pool today...hooray!! Have mesh cover...after vacuuming out stuff on bottom...do I focus on ph, TA, Chlorine levels or CYA first? Thx!!
