I just opened my pool also and was pleased to see it was crystal clear as well. All I did was add a gallon of bleach when I closed it up for the winter. I do not have a quality test kit yet but the one I do have has my levels as follows (27' AG)

TC 3
ph 7.2
akl 110-120
cya Out of drops will post back later.

should my chlorine be higher??

I was under the impression there would be alot of work to do to my pool when I opened it up in the spring.
