Alkalinity in pools is an extremely important topic as it’s what helps  prevent sudden pH changes. Total alkalinity is a measure of alkaline substances  in this case, ionic compounds, that act as buffers that resist pH change.

Don’t worry, this is just a bunch of chemistry and scientific mumbo jumbo  that you really don’t need to know. What is important to understand is that  alkalinity helps stabilize the pH balance in your pool, and keeping it within  normal range can save you a lot of headaches as well as solve a lot of  problems.

The recommended range for a swimming pool’s total alkalinity is between 80  and 120 parts per million. Any good pool testing kit will let you determine the  range, and it’s important to test often.

So, when it comes to alkalinity there are really only 3 states in can be in:  Too High, Too Low and Just Right.

Low Alkalinity With low alkalinity your pH levels can swing back  and forth between too high, and too low. It’s not uncommon for these numbers to  shift drastically causing an unbalance in your pools pH.

Some problems that are associated with this include: -Chlorine  inefficiency -Metal Corrosion -Pool Staining -Scale

You can easily raise a pool’s alkalinity by using a chemical called sodium  bicarbonate which is, baking soda. The recommended dosage is 1.5 pounds of  sodium bicarbonate per 10,000 gallons of water. If you’re unsure how much water  you have you can find a good estimate by using this formula: Read More→
