Pool Time at Mac App Store analyse

After you test your swimming pool water, log the results in Pool Time and it will calculate the Langelier Saturation Index (LSI). LSI is an indication of water balance. An LSI between -0.3 and +0.3 is considered balanced and will have no effect on the pool or equipment. If the LSI is less than -0.3 the water may cause etching, pitting, dissolving and staining of walls, grouting and plumbing. If the LSI is greater than +0.3 the water may deposit excess minerals on the pool and equipment. You should always have your pool water professionally tested. Pool Time is not responsible for any damage to your pool or pool equipment.
