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.

More Information

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.

Frequently Asked Questions

There are so many different chemicals and cleaning products available. This is a personal choice. Some people prefer to use bromine as it is less harsh on the skin and some prefer chlorine as this is easier to regulate and easier to keep control of the levels to make sure they are fine. We provide advice to our customers and help them make the best choice for them. We don’t support any individual brands or type of chemicals – we stock them all.

After you have been using your spa for a few months and had a number of different people in it. Your hot tub will slowly start to build up with bacteria so we have a chemical called a hot tub flush. As you will be draining your hot tub every three months buy the hot tub flush. Place it in your spa, run your spa which will then move the water through the jets and through the pipes and get rid of the bacteria in there.

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.

With every spa purchased we give you a starter pack. You can decide whether you want chlorine or bromine. There are full instructions on the pack and you can always call us for advice.

Shocking a hot tub means applying an ample dose of chlorine (sodium dichlor) or non-chlorine shock (potassium monopersulfate or MPS). One purpose of this treatment is to break-down organic waste contaminants which cause odour and cloudy water.

Cleaning your filters is vital. The best thing you can do is buy a filter cleaner – it is simple and cheap. You put your filter in a bucket of water with the filter cleaner, then let it dry and then re-use your filter.

All chemicals should be added to warm water until dissolved before adding to your hot tub.
Add chemicals to the filter housing so that they go straight through the circulation area.
Leave tub several hours after adding a chemical to have change to circulate before testing and adding more.
Firstly
Test Alkalinity first and get that up to balance TA – increaser will help this one. Make sure levels are ok before adding any other chemicals.
Secondly
PH balance once this is at an ok level you can then add chlorine.
Lastly
Add chlorine last. Do a shock dose for first time or when there is no chlorine present. Shock will be around 60 grams.
Please leave your tub a full 24/48 hours once chemicals are added before you use your tub, once you have used the tub you will need to add more chemicals as the levels would have dropped in the chlorine.
Test your tub daily until you get the hang of a routine when you will need to add certain chemicals.
Cloudy water is PH balance not level to correct either increase or decrease and leave several hours until tested again to let the chemicals circulate round the tub.
Green water is low chlorine or no chlorine we advise shock dose.
