PLEASE NOTE THAT THE FOLLOWING DOSE RECOMMENDATIONS CAN ONLY BE A GENERAL GUIDE, AND THAT THEY ONLY APPLY TO EASYCHEMICALS' PRODUCTS. EASYCHEMICALS ACCEPTS NO LIABILITY FOR LOSS OR DAMAGE.

Accurate dosing of the pool chemicals required to keep your pool in tip-top condition depends on the volume of water in your pool. The following calculators will help you to estimate the doses for some of the common water treatment products.

First, calculate the volume of water in your pool using our on-line Calculator. Just enter the dimensions of YOUR pool (in metres); the Calculator will work out the approximate volume of your pool.

Once you have an estimated pool volume, use the Dosing Calculators to work out the required chemical doses.

1) Calculating the volume of a rectangular swimming pool
2) Calculating the volume of a trapezoid-shaped swimming pool
3) Calculating the volume of a round swimming pool
4) Calculating the volume of an oval swimming pool
5) Converting gallons to litres
6) Converting litres to gallons
7) Adding Stabilised Granular Chlorine to increase chlorine levels
8) Adding pH Increaser (alkaline soda ash) to increase pH
9) Adding pH Reducer (dry acid - sodium hydrogen sulphate) to reduce pH
10) Adding pH Reducer (dry acid - sodium hydrogen sulphate) to reduce total alkalinity
11) Adding Total Alkalinity Increaser (sodium bicarbonate) to increase total alkalinity
12) Adding Hardness Increaser (calcium chloride) to increase calcium hardness
