Reasons Why Your Spa Water is Cloudy
Whether you manage a spa for your business or have a hot tub installed at your residence, cloudy water can put everyone of.
There are various reasons why your spa water might appear cloudy, but the good news is that addressing the issue is generally a manageable task.
Hard Water:
Living in a hard water area, especially prevalent in regions like the south and mid-east of England, can be a primary cause of cloudiness. Checking the pH and chemical balance is the first step toward rectifying the issue. If your spa water hasn't been changed for a while, a buildup of total dissolved solids may occur, the best option is to empty it and refill again.
Sensitivity to Chlorine:
Lower levels of chlorine due to skin sensitivity can lead to increased cloudiness, as bacteria may thrive in inadequately chlorinated water. A sanitiser boost typically resolves this problem, and consulting your manufacturer's instructions is advisable.
Conversely, excessive chlorine levels also makes your water cloudy, so it’s important to check the levels before you take any action.
pH Predicaments:
The pH level of the water, determining its acidity or alkalinity, can be another factor in spa water cloudiness. Easily assessed with a pH kit, adjusting the pH according to the manufacturer’s instructions can remedy the situation. If the water is too acidic, adding a specified chemical can bring it into balance.
Mechanical Mishaps:
If you suddenly start finding your water is cloudy and it’s not due to a chemical reason, these issues might stem from mechanical problems. Excessive bubbles, often giving the appearance of cloudiness, may result from pump malfunctions. Regularly checking the filter system is crucial, as clogs due to debris, oils, and minerals can affect its efficiency. Spa filter cleaner usage typically resolves this.
Another problem might be with the spa pump. If you don’t have this working at regular intervals, it can mean the water isn’t filtered properly which again causes clouding.
The spa system might also get clogged at various parts with small stones and pebbles as well as other debris. An airlock is a little rarer but could affect the flow of water. If this is the case then this should be addressed by a qualified technician.
Biofilm Blues:
In rare instances, a layer of bacteria known as biofilm can form in the inner pipes, creating a thin film that may lead to cloudiness. Regular spa use minimizes the likelihood of biofilm formation, and a thorough cleaning should effectively clear this issue.
In conclusion, maintaining crystal-clear water in your spa or hot tub involves a combination of chemical balance, regular maintenance checks, and addressing mechanical issues promptly. If uncertainties persist, seeking the expertise of a qualified service engineer is recommended to ensure a thorough examination and resolution of the problem.
