I have an intex A/G frame pool (vinyl thingy - 15' x 48") Supposedly the water capacity is 4440 gallons.

We just filled it and I am going to start treating the water.

Test results are:

PH: 8.2
CL: 0 ppm
TA - 60

Which number should I adjust first?
How does lowering the PH effect the TA?
How does raising the chlorine effect the PH and TA?

The reason I ask these like this is becuase in the past I have had a problem with a crazy high TA level and I HAAATTEE that! I am trying to avoid whatever mistake I must've made to get that to happen.

Thanks!
