Dosing calculator

Help & Advice

IMPORTANT: Please note when using any of the dosing calculators that they are only a guide. Swimmingpoolchemicals accepts no responsibility for any damage.

Chemical dosing is an important factor in keeping your pool water in balance and in excellent condition. The following set of calculators will help estimate various dosing rates for the most common pool water problems.

To begin with, calculate the volume of water in your pool using our Pool Water Volume Calculator. Just enter the dimensions of your pool (in metres) and the Calculator will work out the approximate volume of your pool (A metric converter is provided to aid you with this). Following this, use the Dosing Calculators to work out the required chemical doses.

Please note: When ADJUSTING pH LEVELS there are no dosing calculators available. This is due to the fact that we deem it inaccurate to judge due to the high number of variables that effect pH. We advise you to obtain a correct level of total alkalinity (100-160 p.p.m) and then add predissolved small quantites of pH Increaser (Sodium Carbonate) or pH Reducer (Sodium Bisulphate). Once this has circulated for 24 hours retest to find the pH level. The ideal range for pH is 7.2-7.6 p.p.m. POOL WATER VOLUME CALCULATORS -
