Frequently Asked Questions
Will this really stop the burning-eye and itchy-skin feeling my family gets after swimming?
Yes. The leading cause of swimmer eye and skin irritation is unbalanced pH, and low total alkalinity is what allows pH to swing wildly. Clorox Pool & Spa Alkalinity Increaser raises TA into the 80–120 ppm range, which locks pH in place and dramatically reduces red, burning eyes and dry, itchy skin after a swim.
Is this part of a healthy pool water ritual I can do once a week?
It fits perfectly into a weekly wellness routine. Test your water, raise alkalinity first if it is below 80 ppm, then balance pH before adding chlorine. The quick-dissolving granules make it a 10-minute step that protects both the water and your swimmers' comfort.
Does this product support a more natural, less harsh swim experience?
While chlorine is still required for sanitization, stable alkalinity and pH allow chlorine to work at peak efficiency at lower concentrations. Swimmers notice softer-feeling water, fewer chemical odors, and no stinging eyes, which is exactly the calm, restorative experience a backyard pool is meant to provide.
Can I use this in a freshly filled pool before my family swims for the first time?
Yes, and you should. Brand-new pool water has almost no total alkalinity, which causes pH to spike unpredictably. Adding Clorox Pool & Spa Alkalinity Increaser to a freshly filled pool is the recommended first balancing step so that your chlorine works properly and your family's first swim is irritation-free.
Will the granules affect the feel of the water during a quiet evening soak?
No. Once fully dissolved, the granules leave the water crystal clear with no residue, foam, or scent. The result is a more comfortable, neutral-feeling soak that supports a relaxing end-of-day swim ritual.
How do I use Clorox Pool & Spa Alkalinity Increaser step by step?
1. Test your pool water to confirm total alkalinity is below 80 ppm. 2. Calculate the correct dose using the Clorox Pool App or the chart on the label based on your pool's gallonage. 3. With the pump running, broadcast the granules evenly across the deepest part of the pool. 4. Allow the pump to circulate for at least one hour, then retest TA. 5. Repeat if needed, and only then move on to pH and chlorine balancing.
How much do I add to raise alkalinity in my pool?
The general rule is 1.5 lbs of Clorox Pool & Spa Alkalinity Increaser per 10,000 gallons to raise total alkalinity by about 10 ppm. Always confirm with the Clorox Pool App for your exact pool size and current TA reading so you do not overshoot.
How long after adding alkalinity increaser can I swim?
You can usually swim within 1 to 2 hours after the product has fully dissolved and the pump has circulated the water. Always retest before swimming to confirm TA and pH are in the recommended ranges.
Is this product compatible with liquid chlorine sanitizers?
Yes. Clorox Pool & Spa Alkalinity Increaser is fully compatible with pools that use liquid chlorine, chlorine tabs, salt chlorine generators, and most other common sanitizing systems. It contains no ingredients that interfere with any sanitizer type.
Does it work with saltwater pools?
Yes. Saltwater pools still require balanced total alkalinity to keep pH stable, and this product works the same way in salt cells as it does in traditional chlorine pools. In fact, saltwater pools tend to drift in pH faster, making regular TA maintenance even more important.
What is included in the package when I order it?
You will receive a 5 lb resealable tub of Clorox Pool & Spa Alkalinity Increaser, or three 5 lb tubs if you select the Pack of 3 option. No additional accessories are required, just a pool test kit, which is sold separately and available anywhere pool chemicals are sold.
Are there any safety concerns I should know about before using this product?
Always wear gloves and avoid inhaling dust when handling. Never mix this product with any other pool chemical, especially acids or chlorine products, as dangerous reactions can occur. Store the sealed tub in a cool, dry, ventilated area away from children, pets, and incompatible chemicals.
How long does a 5 lb tub last under normal use?
For a typical 15,000-gallon residential pool, a 5 lb tub provides multiple alkalinity treatments across a full swim season. Pools that reflood, have heavy rain exposure, or see high bather loads may need more frequent dosing, which is why the Pack of 3 is a popular option for season-long coverage.
What is the difference between alkalinity increaser and pH increaser?
They are related but not interchangeable. Total alkalinity is the buffer that keeps pH stable, while pH is the actual measure of acidity. You should always adjust alkalinity first to the 80–120 ppm range, then fine-tune pH. Using a pH increaser without first raising alkalinity will lead to constant pH swings, which is why a dedicated alkalinity product like this one is the correct first step in any balancing routine.
