Disinfection is an indispensable part of swimming pool maintenance. This article introduces the selection and application of Chlorine Tablets in swimming pools.
The disinfectant required for daily disinfection of swimming pools is usually slow-dissolving and slowly releasing chlorine, so that it can achieve the purpose of long-term disinfection. And it can well inhibit the growth of algae in swimming pools. Next, we will introduce why chlorine tablets are preferred and how to choose suitable and high-quality chlorine tablets.
Why choose chlorine tablets?
Common forms of swimming pool disinfectants are: tablets (trichloroisocyanuric acid tablets), granules (sodium dichloroisocyanurate granules, calcium hypochlorite granules), powder (trichloroisocyanuric acid powder) and liquid (sodium hypochlorite).
The chlorine tablets commonly used in swimming pools are usually trichloroisocyanuric acid tablets. There are two common specifications of 1 inch and 3 inches. That is, we often say 20g tablets and 200g tablets. And the size can also be customized according to the needs of the pool owner.
- And it already contains Chlorine Stabilizer (also known as cyanuric acid or CYA). It can prevent the free chlorine in the swimming pool from being lost under ultraviolet rays. It plays a role in stabilizing the chlorine content in the swimming pool. It is more friendly to open-air pools and outdoor pools.
- TCCA tablets dissolve slowly and can provide continuous disinfection, which can ensure a long-term and stable supply of chlorine for disinfection.
- The dosing method is convenient. You only need to add them to the doser, such as float, skimmer, and feeders. And the amount of addition can be adjusted according to demand. Granules, liquids, etc. can only be splashed, and the dosing is relatively more frequent.
- Long shelf life, stable effective chlorine content, unlike sodium hypochlorite, not easy to overflow.
- High effective chlorine content, one chlorine tablet can treat a large amount of water, which is more economical in the long run.
- And they are easier to handle, store and transport than granular chlorine or liquid chlorine.
Key factors to consider when choosing chlorine tablets
Chlorine tablet size
Usually, the size should be selected according to the size of the swimming pool and the size of the doser. Usually, large swimming pools require more disinfectants, so 3-inch chlorine tablets are generally preferred. 1-inch and smaller tablets are usually suitable for smaller swimming pools or hot tubs, hot springs and other places.
Available chlorine content and dissolution performance
TCCA typically contains 90% available chlorine. There is almost no residue after dissolution. And it dissolves gradually during the solvent process, without tablet collapse.
Be careful when your TCCA tablets behave as shown in the left picture below when dissolving. Maybe there is a problem with the pressure of your tablets, or even insufficient available chlorine content and other impurities.
Tips for using chlorine tablets
To get the most out of chlorine tablets, follow these best practices:
Test water quality regularly: Use a reliable pool test kit or test strips to monitor chlorine levels. Aim for 1-3 ppm of free chlorine.
Use the right dispenser: Avoid placing tablets directly into the pool, as they can damage the surface. Instead, use a floating dispenser, skimmer basket, or automatic chlorinator.
Balance other chemicals: Maintain proper pH (7.2-7.8) and cyanuric acid levels to optimize chlorine efficiency.
Store tablets safely: Keep chlorine tablets in a cool, dry place away from children and pets.
Common Mistakes to Avoid
Over-chlorination: Adding too many tablets can result in excessive chlorine levels, causing skin irritation and equipment damage.
Ignoring stabilizer levels: Chlorine will be less effective if cyanuric acid levels are too high. Regular testing is essential.
Invest in high-quality TCCA tablets and have the peace of mind of knowing your pool is well protected. For expert advice or product recommendations, don’t hesitate to contact us – we’re here to help you make the best choice for your pool.
