This calculator requires the use of Javascript enabled and capable browsers. This calculator is designed to help you determine the chemical condition and make suggestions concerning the re-circulating water in a pool, spa, pond, fountain or waterfall. Throughout this set of calculators, the generic term water source is meant to include or mean any water source with re-circulating water within. The terms pool and spa are specific in chlorination. The Pool Chemical Conditions Calculator is designed to help you by automatically computing the correct amount of chemical you'll need to adjust your water source's water. Simply enter the correct information about your water source at each prompt and let the calculator do the work! All you need to know before you get started is your water source's volume in gallons, what type of chlorine you are currently using (liquid, cal hypo, dichlor, etc.) and your water source's current reading for the variable you're trying to adjust. Based on your data entry, The Pool Chemical Conditions Calculator will give you the approximate amount of chemical to add for the selected adjustment. As a caveat, all chemical recommendations are for water sources under normal conditions. All calculated amounts are approximate. This is at best a close approximation based on data you supply. We are not responsible for any chemicals you add to your water source (pool, spa, fountain, waterfall, pond or other water location), or for any liability resulting from following the suggestions made on this web page. When in doubt, add less chemical than called for and re-test before adding more. For further information, please contact a water chemical expert. Each calculator is independent of the others. After doing one calculation, you may go to another or you may click on Clear Values and do another calculation on the same one.
In these calculators, the abbreviation PPM is for parts per million. The data entry range is the workable range for all values; the range for Volume (quantity) Of Water is 1 to 9,999,999 gallons. The range for Alkalinity and Calcium Hardness is 0 to 9,999 while the range for Cyanuric Acid is 0 to 999 PPM. The range for Total Chlorine and Free Available Chlorine is 0 to 99.9 PPM.
