Pool Alkalinity Booster — 10 lb Sodium Bicarbonate for Pools
Product description
This product is sodium bicarbonate specially formulated for swimming pools to increase total alkalinity and help keep pH levels stable. Each bag contains granular sodium bicarbonate suitable for adding directly to circulating pool water. Typical packaging is a 10 lb bag, and some sellers offer multi-pack options for larger-volume needs.
Use: Test your pool’s total alkalinity with a reliable kit before application. The product has a clear dosing guideline—11 ounces of the powder will raise alkalinity by about 10 ppm in 5,000 gallons of water. Add the recommended amount while the pump and filter are running, pouring slowly near a return jet so the material disperses and dissolves quickly. Refer to the included dosing chart for exact additions based on pool volume and current alkalinity.
Target alkalinity ranges vary by surface: fiberglass pools generally aim for 70–100 ppm; marcite, painted, tile, or exposed aggregate surfaces usually target 80–120 ppm; and vinyl-lined pools commonly require 120–140 ppm. Regular alkalinity control helps your sanitizer work more reliably and minimizes scale formation, metal corrosion and etching of plaster or other pool finishes. Store the sealed bag in a cool, dry place between uses.
Pros
- Fast-dissolving sodium bicarbonate that stabilizes pH
- Clear dosing guidance (11 oz = +10 ppm per 5,000 gal)
- Helps prevent corrosion, scale, and surface etching
Cons
- Requires careful measurement for large pools
- Powder can clump if exposed to moisture
- Some packages lack a pour-friendly opening
VerdictA straightforward alkalinity increaser that does what it promises: raises total alkalinity, reduces pH drift, and helps prevent scale and corrosion. The powder dissolves fast and is easy to apply directly to circulating water. Use a reliable test kit before dosing and follow the dosing table to reach target alkalinity for your pool construction. It’s a practical choice for routine maintenance if y

Balanced Water, Clear Results
More economical than many alternatives. Dissolves fast and seems high quality — leaves the water clear. I pour slowly near the return to distribute it. Keeps pH steady and is an essential step in pool care.

Clear Instructions and Practical Packaging
Raised alkalinity after a large refill. I received two 10 lb bags and a 5 lb bag; the tear lines make pouring easy and the bag sizes are manageable. Dissolves immediately and readings increased as stated. Resealable bags keep it tidy between uses.
