Please Note: DO NOT MIX WITH ANY STABILISED CHLORINE AS IT WILL EXPLODE! Please make sure your skimmer is free from all other types of chlorine before pouring it into the skimmer. Stabilised Chlorine Granules Without use, most pools naturally lose free chlorine at an average daily rate of around 2 to 3 ppm, though this is influenced by things like water temperature, UV exposure, and the cyanuric acid level. Reason for Testing: Calcium hardness is usually a problem for tiled pools in soft water areas. This is due to there not being enough calcium in the water so it will dissolve the calcium in the grout making it soft. In general this is not a problem in hard water areas as the water contains sufficient calcium. User tip: for 20-gram tablets, fill up the floating dispenser and adjust the collar accordingly. The tablets will take 5-7 days to dissolve.

Split this total amount into 4 smaller doses. Apply each 1/4 dose, allowing time to thoroughly circulate (2-3 hours for commercial pools / 6-8 hours for domestic pools) before re-testing chlorine/bromine level and if necessary adding further doses. Bromine is an alternative swimming pool sanitiser chemical to chlorine. Bromine offers a number of benefits for maintaining pool water, acting as a sanitiser, oxidiser and algaecide for your pool. While chlorine is the more common choice among pool owners, bromine is the chemical of preference for spa and hot-tub owners due to its superior effectiveness in warmer temperatures. Using a brominator and BCDMH sanitiser (bromine tablets)

Your cyanuric acid level (CYA) plays an important role here. The more of it you have in your water, the higher this limit will be. This is because CYA effectively weakens your chlorine after bonding with it. Monitor your pH level. Chlorine works best at a lower pH level, so letting your pH drift too high could result in having to add more chlorine. The sweet spot for pH is between 7.2 to 7.8. Reason for Testing: Maintaining the correct level of alkalinity in your pool helps prevent unwanted changes in the pH levels. If the alkalinity level is too low then the smallest amount of chemical treatment will alter the pH. If the alkalinity level is too high (over 180ppm) then it becomes very difficult to alter the pH. A level greater than 80ppm stabilises the pH of the water so that any chemical treatments or environmental factors will not rapidly alter the pH. Carefully add the resulting solution to the pool whilst the pump(s) are turned “on”, preferably near to the water inlets to aid distribution

User tip: If you’re using our multifunctional tabletswhich already contain algaecide, you should only dose your pool with 1 litre of algaecide for every 10,000 gallons of pool water at the start of each season. After that initial dose, the multifunctional tablets will supply sufficient algaecide to help prevent algae from getting established. Our most popular algae treatment, polyquat algaecide,is absorbed by organic debris such as leaves and dead algae, so it‘s important to clean the pool thoroughly with a brush or vacuum cleaner before starting the chemical treatment. With that predicament in mind, it’s important to make sure the alkalinity level of your pool is correct before any pH alterations are carried out. After the correct alkalinity level is established, test the pH level of the water. If the pH level needs increasing further, add sodium carbonate (pH plus)and, if it needs decreasing, add sodium bisulphate (pH minus). Most pool owners use sodium thiosulfate, sodium sulfite, or sodium metabisulfite. They’re all just as effective as one another and none will drastically impact the rest of your water chemistry, so buy whatever is easiest or cheapest in your area. Proper testing. Always get an accurate read on your chlorine level before adding more to your water. Consider investing in a liquid testing kit for the most reliable results.

Safety & Use:

You’ll need some testing strips to know the chemical concentration in your pool and keep them at the correct level.

Let’s finish up with some practical tips on how to prevent your chlorine level running away from you in future. There are two types of chlorine available to use as sanitisers. These are stabilised and unstabilised chlorine. Stabilised chlorine Do not pour this product into a pool skimmer basket containing chlorine tablets or any other product. But where to start? What products do you need to maintain your pool? And how do you use them effectively? To help you wade through the myriad of dos and don’ts that pool maintenance brings with it, we’ve put together a comprehensive guide covering: Never mix with any other chemicals including cleaning products and chlorine products, as a dangerous reaction my occur.We created a ‘chlorine neutralizer dosage’ calculator so you can adjust the values yourself and get the exact dosage for each type.
