Review: Good price - Competitive price and quick delivery ## Features - This functions as a buffer for the water's pH levels and enables you to control the levels better. Therefore, you should always give attention to the total alkalinity before you start looking at the pH levels themselves. - Ideally, your hot tub should have a total alkalinity value of around 80 to 120 ppm (parts per million). - Anything that is above or below this value will mean that it will be harder to get the pH levels right. - As the total alkalinity of the hot tub water can change as you try to adjust your pH levels, - Therefore it is best to check the total alkalinity first. - SpaChem Total Alkalinity may be dispatached in 5kg Pails ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01KGGTIQO | | Benefits | Alkalinity Increaser,Alkalinity Raiser | | Best Sellers Rank | 17,323 in Garden ( See Top 100 in Garden ) 26 in Pool Balancers | | Brand Name | SpaChem | | Country Of Origin | United Kingdom | | Customer Reviews | 4.7 4.7 out of 5 stars (57) | | Item Form | Liquid | | Item Weight | 5 Kilograms | | Manufacturer | SpaChem | | Unit Count | 5000.0 gram | ## Product Details - **Brand:** SpaChem - **Item form:** Liquid - **Item weight:** 5 Kilograms - **Number of items:** 1 - **Product benefits:** Alkalinity Increaser,Alkalinity Raiser ## Images ![5kg Spa Total Alkalinity Increaser, Pure TA, Alkalinity Raiser plus water balancer - Spa Chemicals for hot tubs, spa's, swimming pool water treatment (Bulk Buy) - Image 1](https://m.media-amazon.com/images/I/51hCv5nNS9L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for my outdoor pool *by C***Y on 1 September 2025* Good item, you will need a few if you have a big pool, as you need to use every couple of days. ### ⭐⭐⭐⭐⭐ Good price *by A***R on 22 April 2019* Competitive price and quick delivery ### ⭐⭐⭐ Didnt work *by C***A on 25 September 2022* It didnt work.
