Hello, I recently purchased a LaMontte ColorQ 11. I did this because I fired my pool guy because he was not doing what he said he was going to do and he was not truthful. Anyway My TDS and Calcium Hardness was through the roof. So I did a total drain of my pool and I have it balanced. I have taken my reading and a bottle of test water to my local Leslie's Pool Supply. My readings and Leslie's readings differ a bit and was wondering who I should trust. They said my PH was 8.0 with a demand of 3 I got 7.8. They said my Calcium Hardness was 210 Im getting 325. Who should I trust ? I checked and rechecked with my CQ11 and get consistent results.
Thanks
