We just did a drain and refill of our inground gunite pool. it is 25,000 gallons. My son took a sample to the local pool store to get an analysis of the water done. I would like to go a different route than purchasing the products that they were pushing but am having a hard time making sense of some of the stuff here. Here's the breakdown from the H2O analysis we got:

FAC 1 ppm
TAC 2
CH 70 ppm
CYA 0 ppm
TA 70 ppm
PH 7.6
Copper 0 ppm
Iron 0 ppm
TDS 260

Any help is greatly appreciated.
