The fact that you’re reading this indicates you already appreciate the importance of taking good care of the water in your swimming pool. As part of this, you might be vigilant about the risk of the pool water becoming cloudy.
If such cloudiness occurs in your pool, the cause of this might well be algae in the early stages of growth. However, there can also be other causes of cloudy pool water, such as chemical imbalances, debris, and/or bacteria.
Such risks underscore why you should always have the right swimming pool chemicals such as algaecides, clarifiers, and shock chlorine on hand to help you maintain your pool water. And let’s be honest – cloudy pool water hardly looks healthy and safe to swim in. So, if cloudiness becomes apparent, you might well act swiftly to tackle it in your pool.

But if cloudiness in your swimming pool water indicates it may be unsafe to swim in, can you assume that crystal-clear pool water is safe and healthy? The short answer is no, and below, we explain why.

Water clarity is one factor in keeping a pool clean – but it isn’t the only factor

Your swimming pool looking clear enough to grace the front of a holiday brochure might have you beaming with pride, but this is no guarantee of its health and safety for swimming.
Circulation, filtration, and chemistry all feed into the ultimate health of a swimming pool’s water, and not all issues with pool water produce an obvious visual sign such as cloudiness. This is why it is so important to have a regular testing regime in place for your pool, checking the water pH, chlorine, total alkalinity, and calcium hardness.

Your pool water should be checked daily for both sanitiser and pH. As for total alkalinity, this should be tested every week, while water hardness ought to be tested every month. Fortunately, Pool Warehouse stocks an extensive range of testing and dosing products to make these processes quick and easy.

‘Clear water equals safe water’ is a dangerous myth

So, to reiterate: no, swimming pool water being clear does not automatically mean it is safe and healthy to swim in. This is why, as the owner of a swimming pool, you will require a good understanding of such key elements of pool water chemistry as water sanitisation and water balance. This will then enable you to follow the right maintenance routine and use the most suitable products.

In the event, for example, of algae beginning to grow in your pool and bringing about cloudiness, you will need to know that shock chlorine must be used first to clear the water, followed by pool clarifier.
