Aside from your sanitizer, the pH level is the most important aspect of water chemistry, whether it is in your pool or hot tub, your swimming pool, or even your drinking water!

In our last blog, we covered the topic of routine spa or hot tub draining in order to help protect the internal equipment of the spa, and to also maximize chemical efficiency to protect bathers against bacteria. This time, we will cover the basic startup of your spa.
A typical spa or hot tub contains around 400 or 500 gallons of water. With such a small body of water, even the smallest amount of use can add tremendous bather waste. Think of it this way: 5 people in a spa equates to about 160 swimmers in about 16,000 gallons of water– a large above ground or small inground pool!
Aside from bather waste, chemical treatments and water evaporation also cause the total dissolved solids (TDS) to increase.When TDS is high, it is extremely difficult to keep the water chemistry in balance, and when the balance is not proper, the spa equipment can be damaged. This is why a regiment of occasional draining and refilling is necessary.
