Small changes, +-0.4, with pH between 7.2-7.8, TA around 80-120, and Borate near zero will be approximately correct. These numbers are only suggestive of the relative magnitude of the pH change you can expect. Irregularly shaped pools can be approximated by estimating the average length and width and using rectangular. That means, to get how many gallons of water your swimming pool holds, you need to multiply the pool volume in cubic feet by 7.5. A good approximation is the shallow end depth plus the deep end depth divided by two. Getting the accurate pool volume is necessary, and this post will help you find the capacity of your rectangular, rounded, triangular, and even irregular-shaped pools. If the depth varies, use the average depth of the pool.
Also, keep in mind that the volume of powders can vary from manufacturer to manufacturer.

Unless you are SLAMing your pool, it is always best to add less than the full amount, wait a little while to allow the addition to mix thoroughly, and then retest to see where you are. There are many situations that are not covered by these basic guidelines. Note: Suggested goals are simply a starting point. Note: Be careful if your CYA is really and truly zero! With CYA above 90 we recommend replacing water to get CYA down before you start the SLAM process. Greater than 0.6 is suggestive of problems for all pools.ĬYA level in the Now column for outdoor pools. Less than -0.6 is suggestive of problems for plaster, tile, stone, and pebble pools. Note: The pH should be tested and adjusted as needed after increasing the borate level.Ĭalcite Saturation Index - requires pH, TA, CH, CYA, Temp, uses Borate, Salt Of 31.45% muriatic acid to compensate for the pH increase.
