Hi there I have a 18' AG pool, 1/2 horsepower pump, ta40 sandfilter, 1 skimmer, 1 center drain, hard plumbed 1 1/2". Here are my results :

FC 5
CC 0
TC 5
pH 8.0
Alk 200
Cal 200
Cya 20
Temp 84

I'm getting concerned about ph climbing and the Alk and Cal abit high. What are the steps I need to take to adjust my water. Thanks for the help. DC.
