I'm a relatively new pool owner in Brisbane and wanted to know if other people use pool shops exclusively for their water testing or as a back up to their own water tests?
A few times now I have taken water samples to three different pool shops on the same day (for giggles) to see how they compare...
One shop uses a computer to test, one uses test tubes and the other a combination of the two. Ironically, every time the test results are all over the place from each shop. Some readings are similar and some are way off.
One shop is telling me to add more buffer and the other is telling me it is good... One is telling to boost the SWG the other is saying its good...
I'm happy to test my own water to keep a check - but was hopping the pool shops would give more consistent results then my cheap test kit.
Anyone else find the same?
