Maintaining water chemistry is very important with swimming pools and spas. Keeping the water chemistry within the specified ranges will not only ensure clean and clear water; it will also provide healthy water for swimmers and prolong the life of the pool and spa equipment. It is important to note that the frequency of pool use and varying weather conditions will affect the amount of sanitizers and other balancing chemicals that you may use. Test your water with Testing Strips and by stopping by one of our two store locations with a water sample for a step by step chemical analysis.
ALKALINTY
Total Alkalinity serves two purposes in swimming pools and spas:
- “Buffers” pH levels
- Protects Copper coils and other metals in Heaters
When the TA is in range, it prevents rapid pH changes & stabilizes pH levels. If both TA and pH need to be adjusted, always adjust TA first, then adjust the pH.
LPS ideal Total Alkalinity range: 80-140ppm
To adjust TA:
- Turn pump off for 10 minutes
- Broadcast Alkalinity Increaser in center/deepest part of pool
- Wait 10 minutes then turn pump on
Test water 8 -12 hours later to see if more adjustment is needed
Alkalinity Increaser: Brings Alkalinity Levels up
pH Decreaser: Brings Alkalinity down (hydrochloric acid may also be used)
pH
The pH should only be adjusted when the alkalinity is within the proper range.
LPS ideal pH range: 7.2-7.6
** Chemicals used to adjust pH always get broadcasted around the pool**
**Test water 8 -12 hours later to see if more adjustment is needed**
pH Increaser (Up) : Increases pH Level
pH Decreaser (Down): Decreases pH Level
SANITIZER
Once pH and alkalinity are balanced, it is time to sanitize your water. Chlorine is the most common
form of sanitation in swimming pools and spas. Shock your pool with either liquid or granular chlorine every 7 – 14 days at night depending on the weather, water clarity, and/or how many people use the pool. Shocking pool water kills and oxidizes organic waste and keeps the water clean and clear.
LPS ideal Chlorine range: 1-4ppm
To maintain your ideal chlorine level, use chlorine tabs or chlorine sticks.
Remember: One 3” tab or 8oz stick per 10,000 gallons per week
Example: A 20,000 gallon pool will use two 3” tabs or 8oz sticks a week
**Do NOT over-use Chlorine tabs or sticks. It can lead to high levels of Cyanuric Acid/Stabilizer, which can damage the liner and equipment. It can also harm swimmers**
PLEASE NOTE: There are other chemical levels that need to be balanced which your test strips cannot measure. We recommend bringing in a water sample from your pool at least 4-6 times per season for a professional analysis.
