Hello Everyone. New gunite pool owner here. I've lurked on the forum for a while now and there is a lot of great info. I had intentions of never setting foot in a pool store and taking care of everything myself based on what this forum has taught me. Unfortunately my pool builder requires me to provide them with a weekly water test from a "pool professional" ie... the teenager working at the local pool store, for finish warranty purposes. My problem is I am getting wildly different results between my testing and the "pool professionals" Yesterday I did a test... I tested a sample myself using my digital LaMotte ColorQ and I have a LaMotte Tracer for Salt/TDS (which I recently calibrated with the provided calibration standard). After I tested myself I took a sample to two different pool stores. Here are the results...
As you can see both pool stores were not even in the same ballpark... Which test would you believe?
My Test | Pool Store "A" | Pool Store "B"
FC 2.86 | 3 | 4
PH 7.3 | 7.7 | 7.5
ALK 86 | 100 | 50
CH 296 | 275 | 200
CYA 66 | 20 | 50
Salt 3500 | 3300 | 3600
