Highly effective bromine granules from the premium surespa range of hot tub products.
Bromine is an easier sanitizer to use than chlorine and it performs better at the high water temperatures found in hot tubs. It is less of an irritant, so is less likely to cause skin or eye problems, and it leaves much less odour in the water.
surespa bromine granules are highly effective, both for general sanitation and algae control and for shock treatment. They are close to pH neutral and so they won't cause any corrosion of your hot tub equipment.
Initial dose : When first filling your hot tub, use bromine granules to give an initial shock dose of sanitizer. Pre-dissolve the weight of granules recommended in the table below in clean water in a clean plastic bucket, agitating well to make sure that the granules are completely dissolved. Apply the solution to the spa water whilst the pumps are turned on to aid distribution of the sanitizer. You should aim to maintain a bromine level of 30ppm for 1 hour. After this time, allow the bromine level to reduce to 3-5ppm. Test the water after 30 minutes and at intervals as required, using bromine test strips dipped into the water. Do not allow anyone to get into the water until the bromine level has reduced to less than 5ppm.
Daily maintenance : Check the bromine level daily and re-apply granules as required to maintain a bromine concentration of 3 - 5 ppm. The amount of product you will need to use is given in the following table.
|Size of your hot tub||To increase the bromine level by..|
|1000 litres / 220 gals||3g||8g|
|1500 litres / 330 gals||4g||12g|
NB : It is important to maintain a pH level of 7.2 - 7.8 whilst using bromine to sanitize your spa. Outside of this range the bromine will not sanitize effectively.
