Why Alkalinity is the Secret First Step to Effective Pool Chemistry
Hey there, Property Managers! Ever wonder why your pool's chemistry is off, even when you're doing everything by the book? The secret sauce might just be something you've overlooked: Alkalinity.
Yep, it's not just about chlorine and pH levels. Let's break it down
The ABCs of Alkalinity
Alkalinity is like the unsung hero of pool chemistry. It helps stabilize your pool's pH, making sure it doesn't swing from one extreme to another. Think of it as the buffer zone that keeps your pool's pH in check.

Why is pH Lock and pH Bounce Bad News?
Alkalinity Level | Condition | What Happens? |
|---|---|---|
Low (Below 80 ppm) | pH Bounce | Your pool's pH level will fluctuate rapidly, making it hard to control. |
High (Above 120 ppm) | pH Lock | Your pool's pH level becomes resistant to change, making it difficult to adjust. |

How to Adjust Alkalinity
"Before you begin to adjust the total alkalinity in the swimming pool, be sure you know how large your pool is (gallons) and what your target range is. You ideally want to be in the middle of the range between 80-120 ppm." - FROG Products
Raising Alkalinity
Use sodium bicarbonate (baking soda). Here's how much you'll need:
Amount of Sodium Bicarbonate | Alkalinity Increase (ppm) | Pool Volume (10,000 gallons) |
|---|---|---|
1.4 lbs | 1 ppm | 10,000 gallons |
Lowering Alkalinity
Muriatic acid or sodium bisulfate is your go-to. Check this out:
Amount of Muriatic Acid | Alkalinity Decrease (ppm) | Pool Volume (10,000 gallons) |
|---|---|---|
25.6 fluid ounces | 1 ppm | 10,000 gallons |
How OftenShould I Check Alkalinity?
So, you've got the lowdown on what alkalinity is and why it's crucial. But how often should you be checking it? Good question!
According to experts, you should aim to check your pool's total alkalinity once a week. Consistent testing ensures that you catch any fluctuations early, making it easier to maintain that perfect pH balance.
Action Steps
Test Alkalinity: Aim for 80-120 ppm.
Adjust as Needed: Use the tables above.
Retest: Always retest to make sure you've hit the sweet spot.
Log It: Keep a record. Trust us, it helps.
Conclusion
Alkalinity might not be the star of the show, but it sure is the stage manager that keeps everything running smoothly. Get this right, and you're well on your way to a pool that's not just sparkling, but safe.
