## Customer Reviews

### ⭐⭐⭐⭐⭐ Game Changer - an indispensable instrument for measuring Alkalinity.
*by N***R on 22 November 2023*

This is an excellent means of determining the Alkalinity in a marine aquarium. After working through the simple instructions for the first time it only takes a couple of minutes to conduct the test on the next occasion. The ease of use encourages regular testing. I have to agree with the presenters of BRStv on Youe Tube that Alkalinity, not Calcium, is the key parameter in a marine aquarium, along with Specific Gravity and pH. These are vital 3.In spite of the cost, which is still quite reasonable, this Checker is indispensable. It takes a fraction of the time needed to use a conventional test kit and it has been widely proven to be highly accurate.You will soon wonder how you ever managed without it.

### ⭐⭐⭐⭐⭐ Best tester on the market

### ⭐⭐⭐⭐⭐ Excellent
*by A***N on 22 January 2021*
