Objective
Learn how to use Easy Alkalinity Down to safely reduce high Total Alkalinity in your pool, effectively preventing "pH lock" and keeping your water perfectly balanced.
The Danger of High Alkalinity
Total Alkalinity acts as a buffer for your pool's pH. When Alkalinity is too high (above 120 ppm), it aggressively pulls your pH upward. No matter how much acid you add to fix the pH, high alkalinity will stubbornly drag it right back up within days. Easy Alkalinity Down uses premium sodium bisulfate to safely and efficiently lower that buffer. By dropping your alkalinity back into the ideal 80-120 ppm range, you allow your pH to finally stabilize, protecting your equipment from scale buildup and keeping your water comfortable.
Prerequisites
Have a reliable drop test kit to measure your current Total Alkalinity.
Do not attempt to adjust Alkalinity and Calcium Hardness on the same day.
Step-by-Step Instructions
Activate Circulation: Make sure your pool pump is turned to the ON position.
Determine the Dose: Consult the dosage chart on the container. Calculate the required amount based on how many ppm you need to drop.
Targeted Application (The "Slug" Method): Unlike adjusting pH, where you spread the product out, the best way to lower Alkalinity is to pour the product in a concentrated area (a "slug") in the deepest part of the pool, away from the walls and skimmer.
Brush: Use a pool brush to safely disperse any granules that settle on the pool floor.
Wait and Retest: Let the pump run for at least 6 to 8 hours before retesting your Alkalinity and pH.
Troubleshooting Note: Lowering your alkalinity will also naturally pull your pH down. Once your alkalinity is in the proper range, you can use Easy pH Up to fine-tune your pH back to 7.4.
