How to Clean and Maintain Your Swimming Pool or Hot Tub
How to Test, Raise, and Lower Swimming Pool pH Level
You should test your pool pH level as often as you test free chlorine – about twice per week. To raise pH use borax or soda ash (aka washing soda). To lower pH use muriatic acid.
What Should pH levels be in Swimming Pools and Hot Tubs?
The ideal pH level in both swimming pools and hot tubs is 7.4 to 7.6. This is the level where water is most comfortable for swimmers while also maximizing chlorine’s sanitizing ability.
Choosing the right Swimming Pool Stabilizer
There are three types of pool stabilizer: stabilized chlorine, liquid stabilizer, and granular stabilizer. Which type of stabilizer you should use is largely a matter of personal preference. Learn more about pros and cons of each.
How to Test, Raise, and Lower Cyanuric Acid
Test strips are the easiest way to test cyanuric acid. Cyanuric acid is raised by adding chlorine stabilizer containing cyanuric acid. The only way to lower cyanuric acid is by replacing water.
What is the right Cyanuric Acid Level for Swimming Pools and Hot Tubs?
The two most important factors to consider in terms of balancing your cyanuric acid levels are whether your pool uses a salt water generator and how much direct sunlight your pool receives. Most salt water manufacturers recommend higher cyanuric acid levels than traditional chlorine pools.
What is Cyanuric Acid?
Cyanuric acid stabilizes free chlorine by preventing it from evaporating from UV sunlight, which increases the lifespan of free chlorine but decreases its ability to sanitize swimming pool water.
How to Winterize an Above Ground Swimming Pool
emperatures are dropping and fall has arrived! Now is the time to start thinking about winterizing your above ground swimming pool. If you live in a freezing climate, or just don’t plan to use your pool for a few months, it’s a good idea to close your pool. It will save you money on chemicals and power bills, and if you DO live in a freezing climate, winterizing your pool protects it from damage that can be done when things freezes.
What Should Chlorine Levels Be in Swimming Pools and Hot Tubs?
The Association of Pool and Spa Professionals recommends free chlorine levels for both swimming pools and hot tubs be kept between 2.0 and 4.0 ppm. However, the Center for Disease Control recommends free chlorine stay above 1 ppm in pools and 3 ppm in hot tubs.
What is Free Chlorine, Combined Chlorine, and Total Chlorine?
Free chlorine is the amount of chlorine available to sanitize contaminants. Combined Chlorine is chlorine that has combined with contaminants. Total chlorine is the sum of the two.
