    Low Calcium and Calcium Scale

    Thanks, that place is the closest, but they don’t have it. Samui takes too long because of the ferry and is expensive too. I usually go to Surat Thani or order online through Lazada. Do you have an opinion as to what my vacuum is picking up in the photo above? I put it in HCl and it fizzled...

    Low Calcium and Calcium Scale

    Btw, does the CaCl2 have to be bought from a pool store specifically, or would something like this be OK?

    Low Calcium and Calcium Scale

    I have already added about 20kg of CaCl2, and I will add more to get it to 200. I don’t think it can be efflorescence because the pool is not in the ground, it is raised to be level with the house, which is on a slope. There is a clear difference between the tiles above the waterline, which are...

    Low Calcium and Calcium Scale

    So it is possible that I need to add CaCl2 as Pool Math suggests, even though I have calcium scale? Which, btw, occurs everywhere under the water, not just the waterline.waterline.

    Low Calcium and Calcium Scale

    The Taylor calcium drop test shows a level of 120ppm in my saltwater pool, but I seem to have scaling on my marble tiles. I scraped some off and put it in HCl, where it fizzled, which I am assuming means it is calcium. Would it be possible to have calcium scale with a ppm of 120 or could it be...

    Sending a test kit to Thailand

    I saw an old thread about shipping test kits overseas, but I need some updated information. I could not find a company that would ship directly to me so I bought the Taylor K2006 on Amazon and had it sent to my brother in Florida. Does anyone know the best way to get it to me here in Thailand?

    What is this, please?

    I did the acid test for Calcium Scale and it did fizzle. Does it make sense that I could have calcium scale and still be low in CaCl2?

    What is this, please?

    Here is the initial test from a different company that seems more accurate. I did add the CaCl2 and baking soda and then requested a new test from the second company. It was delayed because they were calibrating their equipment, they said. Then when I got it back, I disputed the results, so they...
