Water balance in pools and hot tubs is a relatively simple concept. Take the readings from the most commonly tested parameters (pH, total alkalinity [TA], calcium hardness [CH], water temperature, and total dissolved solids [TDS]) and then use these values in a mathematical formula that produces a number.

Dealing with pool and hot tub water chemistry issues is sometimes confusing and occasionally frustrating because of the many critical components involved. A basic understanding of this topic is often not enough. Sometimes it requires gaining a better understanding of what it takes to maintain healthy, balanced water.

As the weather warms up and the swim season starts, pool water quality begins to suffer and algae often start to grow. Some algae are easy to treat and remove; however, other types can be quite challenging to deal with. The three main types are: green, black, and yellow/mustard algae.
