So my pool has been looking fantastic. My latest issues is trying to lower my TA and raise my pH at the same time. I tested with my k6000 and got this.
TA-140
pH-7.4
FC-5.5

I took a sample to the pool store and got this.
TA-130
pH-6.9
CYA-20
TH-350
TC-5.6
FC-5.6

So who's numbers do I trust? Anyway, they recommended raising the pH and then lowering the TA together with the pH. Kinda nervous because my k-6000 measured my pH at 7.4. any suggestions would be greatly appreciated.
thanks
