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 - Maintaining a desirable total alkalinity reading is critical to holding chlorine residuals - pH levels are easier to control with a corrected total alkalinity - Alkalinity acts as a buffer, improving the ability of your pool water to resist pH fluctuations - Downloadable User Guide Available Under Product Information: Technical Specifications ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00UD97XPS | | Best Sellers Rank | #132,941 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #203 in Swimming Pool Balancers | | Brand Name | SpaChoice | | Customer Reviews | 4.7 4.7 out of 5 stars (187) | | Global Trade Identification Number | 00034261110338 | | Item Form | Granular | | Item Type Name | for Hot Tub | | Item Weight | 4 pounds | | Manufacturer | SpaChoice | | Manufacturer Part Number | 472-3-4021-02 | | Manufacturer Warranty Description | 90 Day Woot Limited Warranty | | Model Number | 472-3-4021--02 | | Number of Items | 2 | | Number of Packs | 2 | | Package Size Name | 2-Pounds | | Product Benefits | Alkalinity Increaser | | UPC | 034261110338 | | Unit Count | 64 Ounce | ## Product Details - **Brand:** SpaChoice - **Item Form:** Granular - **Item Weight:** 4 pounds - **Product Benefits:** Alkalinity Increaser - **UPC:** 034261110338 ## Images ![SpaChoice 2-Pounds 2-Pack Premium Alkalinity Increaser for Hot Tub - Image 1](https://m.media-amazon.com/images/I/61a4izWXFQL.jpg) ![SpaChoice 2-Pounds 2-Pack Premium Alkalinity Increaser for Hot Tub - Image 2](https://m.media-amazon.com/images/I/41D5+enV2-L.jpg) ![SpaChoice 2-Pounds 2-Pack Premium Alkalinity Increaser for Hot Tub - Image 3](https://m.media-amazon.com/images/I/312Dh2bGhHL.jpg) ![SpaChoice 2-Pounds 2-Pack Premium Alkalinity Increaser for Hot Tub - Image 4](https://m.media-amazon.com/images/I/41dNawrf-KL.jpg) ![SpaChoice 2-Pounds 2-Pack Premium Alkalinity Increaser for Hot Tub - Image 5](https://m.media-amazon.com/images/I/51268tW5mNL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - SpaChoice 2-Pounds 2-Pack Premium Alkalinity Up, Alkalinity Increaser for Hot Tub, 100% Sodium Bicarbonate, Made in USA - Leisure Time E5 Spa 56 Chlorinating Granules for Spas and Hot Tubs - Maintains Clean, Clear, Sanitized Water, 5 lbs - EASYTEST 7-Way Pool Test Strips, 150 Strips Water Chemical Testing for Hot tub and Spa, Accurate Test Bromine, Total Alkalinity, pH, Free Chlorine, Total Hardness, Cyanuric Acid, and Total Chlorine --- ## 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.ec/products/194821786-spachoice-2-pounds-2-pack-premium-alkalinity-increaser-for-hot](https://www.desertcart.ec/products/194821786-spachoice-2-pounds-2-pack-premium-alkalinity-increaser-for-hot) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-09-15*
