Spa Alkalinity Increaser Hot Tub pH Increaser Hot Tub pH Decreaser Spa Calcium Increaser Spa & Pool Test Strips ## Features - 2 LB Hot Tub Alkalinity Increaser - Low alkalinity can lead to unstable pH and harder-to-manage spa water. This sodium bicarbonate formula helps raise total alkalinity to support balanced water chemistry and more stable pH levels in hot tubs and spas. - Supports pH Stability - Balanced alkalinity helps buffer pH changes and lower frequent swings. For most spas, keeping alkalinity in the 80–140 ppm range supports stable water chemistry and easier maintenance. - Helps Protect Spa Surfaces & Equipment - Balanced alkalinity helps prevent the pH swings that can lead to corrosion, etching, and scale formation, supporting the longevity of hot tub surfaces, heaters, and fittings. - Fast-Dissolving Granules - The sodium bicarbonate granules dissolve quickly and spread evenly throughout circulating spa water. Test your levels, add 1 oz (2 tbsp) per dose, circulate for 30 minutes, and retest to confirm balance. - Made In The USA - At AquaDoc, we make high-quality hot tub chemicals designed to support balanced, comfortable water. Proudly made in the USA with consistent quality standards. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B09QMNS8KB | | Best Sellers Rank | #3,886 in Patio, Lawn & Garden (See Top 100 in Patio, Lawn & Garden) #28 in Swimming Pool Balancers | | Brand Name | MAV AquaDoc | | Customer Reviews | 4.7 4.7 out of 5 stars (434) 4.7 out of 5 stars | | Item Form | Granular | | Item Highlight | Sodium Bicarbonate Booster Designed to pH Stability and Balanced Water - Made In USA - Hot Tub Chemicals | | Item Weight | 2 pounds | | Manufacturer | Mav Aquadoc | | Manufacturer Part Number | AlkalinityUp-16oz | | Model Number | AlkalinityUp-16oz | | Number Of Items | 1 | | Package Size Name | 2 lb | | Product Benefits | Helps protect hot tub surfaces & equipment, Increases total alkalinity levels, Supports pH Stability | | Unit Count | 32 Ounce | | Upc | 850026022995 | ## Product Details - **Brand:** MAV AquaDoc - **Item Form:** Granular - **Item Weight:** 2 pounds - **UPC:** 850026022995 ## Images ![AquaDoc Total Alkalinity Increaser for Hot Tubs & Spas - 2 lb - Image 1](https://m.media-amazon.com/images/I/71bZHoosDEL.jpg) ![AquaDoc Total Alkalinity Increaser for Hot Tubs & Spas - 2 lb - Image 2](https://m.media-amazon.com/images/I/81acLOdKc9L.jpg) ![AquaDoc Total Alkalinity Increaser for Hot Tubs & Spas - 2 lb - Image 3](https://m.media-amazon.com/images/I/81LxCfKiLQL.jpg) ![AquaDoc Total Alkalinity Increaser for Hot Tubs & Spas - 2 lb - Image 4](https://m.media-amazon.com/images/I/71scryCyQYL.jpg) ![AquaDoc Total Alkalinity Increaser for Hot Tubs & Spas - 2 lb - Image 5](https://m.media-amazon.com/images/I/81Z907fuF6L.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - AquaDoc Total Alkalinity Increaser for Hot Tub - Alkalinity Booster for Spas & Fresh Water pH Balance - AquaDoc pH Increaser for Hot Tub - pH Up for Hot Tub Spa - pH Increaser Hot Tub Chemicals - Balance Your pH Up and Down Levels Effectively - Adjust pH Levels for Hot Tub Maintenance - 32oz - MAV AquaDoc Calcium Hardness Increaser Hot Tub Owners Rely On, Calcium Booster for Hot Tubs & Spas --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/409488424-aquadoc-total-alkalinity-increaser-for-hot-tubs-and-spas-2](https://www.desertcart.de/products/409488424-aquadoc-total-alkalinity-increaser-for-hot-tubs-and-spas-2) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-11-11*
