This easy to use kit enables you to carry out quick, accurate checks on the free bromine and pH levels in your pool or hot tub.
It comprises two test-cells - one for bromine and one for pH, with 20 test tablets for bromine and 20 Phenol Red tablets for pH, with full instructions. Simply immerse the tester in the pool to fill both chambers, tear open the foil seal to release a tablet and add it to the sample WITHOUT touching it with your fingers - as this can affect the reading!
Then - place the soft plastic lid on the tester to keep the water in and agitate for a few seconds to dissolve the reagent tablet. You then hold the chambers up to the light so that you can see and compare the sample against the colour grids - and select the colours that best match your samples and the grids.
What next? Once you establish the level of free bromine and the pH in your pool or spa water, you can then decide how much chemical you need to add to the water to keep the pH in the range 7.2 to 7.8 and sufficient bromine to deal with the swimmer numbers that you anticipate in the next few hours. If the pool is likely to be very busy - carry out the test in the next few hours and add chemicals accordingly. Please note that even a pool or hot tub that is not used for a few hours or days, will still lose bactericide (to atmosphere), and more needs to be added.
