Chlorine is a commonly used chemical to achieve satisfactory bacteriological and chemical purity in spas. It must be present in the ‘free’ form to kill bacteria and oxidise organic matter derived from bathers. Provided the water is balanced, chlorine levels of between 3.0 to 5.0mg/l are sufficient to maintain healthy, clean water. A well managed chlorine treated spa will have no odour and levels of chloramines (combined chlorine) of less than 0.5mg/l. Combined chlorine is created as a result of a reaction between free chlorine and organic matter and is a mixture of Monochloramine, Dichloramine and Nitrogen Trichloride. The latter is mostly produced when the water is not being treated adequately and gives rise to the ‘chlorine’ odour.
AquaSparkle Stabilised Chlorine Granules 1kg
A traditional granular chlorine that is popular with spa owners as it gives dose rate flexibility. These granules are rapid dissolving making pre-dissolving and application easy. The granules have a pH value of about 6.0– 7.0, which is fairly close to the ideal spa water pH level and so will have little effect on the pH level of your spa water.
Frequently Asked Questions
Regular maintenance is essential to prolong the life of your hot tub, so along with water cleaning products like chlorine you will need to pay attention to filters, pipes, and the interior of your tub. Rapid filter clean will keep your filters clear and Spa Shine can help to protect your hot tub from UV rays and chemical degradation.
Miami Spas offer many chemicals and cleaning products to keep your tub in tip top condition. Bromine is less harsh on the skin and chlorine can be easier to regulate and maintain control of water levels. Depending on the type of water in your area you may need additives like Alkalinity Increaser or Water Hardener to prevent excess foam or limescale build up.
Filters are the first protection for bacteria as this is where the debris and all of the bacteria gets sucked down. Filters should be checked once or twice a week to make sure they are still clean – you can purchase a filter cleaner. We recommend changing your filter when you change your water which is every three months. But always check your filters once or twice a week.
Your hot tub will slowly start to build up with bacteria as it is used, so a hot tub flush may be needed. Add it to your spa and run it as normal. The cleaner will move with the water through the jets and pipes effectively flushing all the dirt and bacteria build up, restoring your hot tub to peak condition.
