How to Maintain Your Swimming Pool Water

A purpose-built swimming pool is one of your property’s most important assets and should be treated accordingly. An above-ground pool is a lot of fun during the summer months and also needs to be well looked after.

Here are some easy-to-follow tips on how to maintain the water inside your pool and its walls and surfaces too.


Step 1: Putting chlorine tablets into a floating chlorine feeder.

Buy test strips online or at your nearest pool supply store. They will indicate what is needed to be added during your weekly pool maintenance check-up. If you keep the chlorine level in your pool at 1 – 3 ppm, it will be optimum for pool use and its health.

Not all chlorine tablets are created equal. It can come in 7,5 centimetres/3 inch and 2,5 centimetres/1 inch cakes as well as sticks, bottles, and grains, in a wide range of prices. They all contain bacteria-, microorganism-, and algae-killing chlorine; the cheaper the product, however, the weaker the chlorine concentrate will be.

The 7,5 cm tablets are the most commonly seen chlorine pool cakes. An indication of a quality product is observing how it dissolves in the water. If the tablet begins to crumble after a few days, then it is poor quality containing too much binder and filler; good quality pool tablets keep their shape as they dissolve.

2,5 cm chlorine cakes are well suited to above-ground pools, spas, and smaller size in-ground pools. A concentration of 90 percent Trichloro-S-Triazinetrione is the best amount of chlorine for pools of all types.

How you choose to disperse chlorine in your pool can also affect how long it lasts. Any pool supply outlet will stock automatic chemical feeders and floating chlorine feeders. They are a great help in dispersing the correct metered dose and if properly set, can give you a week or more of not having to worry about chlorine levels.


Step 2: Adding Shock nocturnally every week.

This an important step that should not be neglected. As the chlorine works to clean and sanitise your pool, it binds to other chemicals that are also present in the water, such as nitrogen and ammonia. After the binding occurs, the chlorine is rendered inactive; the resultant bonded molecular structure can cause a range of skin irritations.

To effectively eliminate these combined chlorine molecular structures, it is necessary to add a weekly dose of pool shock treatments overnight, which gives it time to work before the pool is used again. Check the product instructions for dosage, but an average amount is usually 1,3 kilograms/3 pounds.


Step 3: Testing your pool water after adding the Shock

The optimum pH balance for any pool is 7.2, but anywhere up to 7.6 is acceptable. It is important to test the pH if you are adding cyanuric acid or hypochlorite to the pool to extend the lasting effectiveness of the chlorine. If the pH is high, as most pool water is prone to be, adding muriatic acid, also known as Hydrochloric acid, or granular acid to the pool’s deep end while the pump is on, will rectify the problem fastest.

Retest the water six hours afterwards to check, as factors like rainfall can cause the pool’s pH to “bounce”.


Step 4: Adding Algaecide the morning after the Shock

A maintenance dose of algaecide is needed after pool shock. Algae is very opportunistic, and regular checking and dosing will stop your water and pool surfaces from becoming coated with this green pest.


Step 5: Testing your swimming pool’s pH balance twice a week.

Once you have your testing kits from the local pool supply stockist or website, make sure to make a habit of using them twice a week. This regular maintenance is much easier than it is to troubleshoot more serious problems if a week is skipped. Remember to always first adjust the alkalinity, followed by the addition of bromine or chlorine as needed. Then check the pH again to see it has returned to the optimum 7.2 – 7.6 levels.


These regular pool maintenance habits will soon become second nature and will pay off big dividends when summer comes around.
