By preventing pH bounce, corrosion, and scale formation, it protects spa equipment and surfaces while enhancing disinfectant effectiveness. Easy to use with simple dosing and retesting steps, it ensures your spa water stays perfectly balanced for a premium soaking experience. ## Description Critical to alkalinity control, this granular formula effectively raises alkalinity levels which might otherwise cause equipment corrosion. This product is a special compound used to increase the total alkalinity in spa water. Test for total alkalinity with a reliable test kit. The desired range for total alkalinity is 80-140 ppm. This product increases the effectiveness of the disinfectant, and helps prevent scale formation. It also prevents corrosion of metals, etching of spa surfaces, eliminates “bounce”, and maintains pH at the proper level. Easy to use; dissolves quickly. 1. Add 1 oz. (2 tbsp.) to spa water. 2. Allow water to circulate for 30 minutes. 3. Retest water and repeat Steps 1 and 2 until the desired level is reached. For best results, dissolve granular products first by adding to a small plastic pail filled with water. ## Features - The desired range for total alkalinity is 80-140 ppm - Add 1 ounce of this product and retest every 30 minutes until total alkalinity is in the range of 80-140 ppm - Raises total alkalinity and prevents pH bounce ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001GLWL18 | | Best Sellers Rank | #10,846 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #57 in Swimming Pool Balancers | | Brand Name | SpaChoice | | Customer Reviews | 4.7 4.7 out of 5 stars (1,766) | | Item Form | Granular | | Item Type Name | for Hot Tub | | Item Weight | 1 kg | | Manufacturer | Robelle Industries | | Manufacturer Part Number | 472-3-4021 | | Model Number | 472-3-4021 | | Number of Items | 1 | | Number of Packs | 1 | | Package Size Name | 2-Pounds | | Product Benefits | Alkalinity Increaser | | UPC | 034261188306 | | Unit Count | 32 Ounce | ## Product Details - **Brand:** SpaChoice - **Item Form:** Granular - **Item Weight:** 1 kg - **Product Benefits:** Alkalinity Increaser - **UPC:** 034261188306 ## Images ![SpaChoice 2-Pounds Premium Alkalinity Increaser for Hot Tub | Raises Total Alkalinity, 100% Sodium Bicarbonate, Easy to Use, Add 1 ounce and Retest Every 30 Minutes, Made in USA - Image 1](https://m.media-amazon.com/images/I/51Qw5zbjP8L.jpg) ## Available Options This product comes in different **Size** options. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/8563717-spachoice-2-pounds-premium-alkalinity-increaser-for-hot-tub-raises](https://www.desertcart.us/products/8563717-spachoice-2-pounds-premium-alkalinity-increaser-for-hot-tub-raises) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-30*
