Bulk Alkalinity for Big Pools and Smart Savings
After a winter of rain dilution, a partial drain-and-refill, or if you manage a large pool or multiple pools, you may need to add significant amounts of alkalinity increaser at once. The E-Z Clor Alkalinity Up 25 lb box gives you the volume to make major total alkalinity adjustments without the per-unit cost of smaller pouches. Pure sodium bicarbonate is one of the most-used pool chemicals, and buying in bulk just makes sense.
Key Benefits
- 25 lb bulk box — the best cost per pound for alkalinity adjustment
- Pure sodium bicarbonate, the same product used in every pool chemical line
- Raises total alkalinity to the ideal 80–120 ppm buffer range
- Prevents pH bounce that makes water balance a constant battle
- Essential for spring pool openings when alkalinity drops over winter
How to Use
Test total alkalinity. For each 10 ppm increase needed, add 1.5 lbs per 10,000 gallons. Broadcast over the deep end with the pump running. Add no more than 5 lbs at a time and wait 6 hours between additions for accurate adjustment. Test again before the next dose. For spring startups, you may need 10+ lbs to bring alkalinity back to range after months of rain dilution.
