Advantages of Using Pool Clarifier

Who wants to swim in a hazy pool where you don’t know what’s in it. The truth is, it is not healthy to swim in this kind of water situation. In fact, it can be hazardous to your health. Dirty pools harbor all kinds of bacteria that can result in various types of illnesses such as infections, rashes, and diarrhea. 

Hence, it’s important to remove the contaminants in floating in your pool water. The cloudiness in the water is common among pools as it is usually caused by algae, not enough chlorine or filtering. 

When checking the condition of your pool, there are several factors to the condition including the size, filter, water balance, and sanitation. A worn-out filter system, too small filter, inefficient pool sanitation, and poor pH balance can also result in cloudy pool water. Remember to change your filter regularly, especially when the pool is in active use. 

Other factors that may lead to the cloudiness include low chlorine, high pH, high alkalinity, high calcium, and high cyanuric acid among many others. Therefore, you need to make sure that you clean your pool regularly to maintain the water quality.
