Handling 3 common pool water problems

Having your own luxury pool is a fantastic investment in your home, lifestyle, health and fitness; and pool owners do their utmost to ensure their pools are in tip top condition all year round. With all that care and attention, it can be disconcerting if a problem with the pool water emerges. Discoloured pool water makes a pool look unwelcoming, and in some cases this is indicative of a bigger problem that needs to be corrected before the pool can function as normal. Fortunately, most pool water faults can be easily diagnosed by a qualified service engineer who can get the pool running optimally and looking great in no time. In this blog we look at three of the most common pool water problems.

Your pool water has gone green
If you’ve noticed that your pool water has taken on a green tint, this is indicative of algae growth. Algae problems range from mild to extreme. If the water has only a light green tint this represents a mild problem whereas if the pool water is dark green to the point where it is no longer transparent, this will require more work from your service engineer. Whether the problem is mild or extreme, the same procedure is used, however, for extreme cases it’s likely that the procedure will need to be performed multiple times. Typically, the engineer will test the pool water chemistry and add either an acid or an alkali to balance the pH level. After this is complete, any debris needs to be removed from the pool and the filter should be backwashed. Finally, using a chlorine shock will destroy the algae. However, if the problem is severe the engineer may need to perform multiple chlorine shocks.

Your pool water is cloudy
While green pool water is indicative of live algae in the pool, cloudy water is usually the result of dead algae that needs to be cleared away. To begin with, you can manually brush away all the dead algae from the bottom and sides of the pool and then vacuum away all debris. As an additional measure, a flocculent product can be added to the pool which binds all the dead algae together, making it easier to locate and vacuum away. Once the algae have been removed, run the filter until the pool water returns to pristine condition. Your service engineer will advise you on the best course of action when it comes to removing the debris and which flocculent/shock treatments to purchase.

Your pool is losing water
All pools lose a little water through evaporation; this is dependent on a number of factors such as climate and humidity. However, if you find you are topping up your pool water on a weekly basis, it might be an indicator that there is a leak. Not only will a leak impact the structural integrity of the pool, potentially costing you a sizeable figure when it comes to repairs, a loss of pool water can disrupt the pool water chemistry which is not healthy for swimmers.

If you suspect there is a leak, you can perform the bucket test to determine whether or not the pool is losing water due to evaporation or whether there is a more significant issue. Use only a qualified service engineer to assess your pool - they will determine the location of the leak and take remedial action immediately, getting you and your family back into the water swiftly.
