## Description

Fill a test-tube halfway with nutrient, add a few drops of pH Test Indicator, and observe the coloration of the liquid in the test vial. Use 3 drops per 5mL of solution.

Review: Accurate ph meters are expensive and break. This is a better option - Accurate, affordable, lasts a long time, and so easy to use. I’m tired of expensive ph meters breaking on me. I put this in an oral syringe so I don’t have to keep opening the bottle every use. You only need a few drops.
Review: It works - Tried and true. Ol faithful. Never needs to be calibrated. Highly recommended

### ⭐⭐⭐⭐⭐ It works

Tried and true. Ol faithful. Never needs to be calibrated. Highly recommended

### ⭐⭐⭐⭐⭐ If you don't have a test vial, make certain you order the Kit with the vial first;)
*by A***R on December 30, 2020*

Product is great and works as it should. My only problem is user error, no fault of the company's. I neglected to order the kit with the test vial. Fortunately, I have test vials for my aquariums, although their dimensions are slightly different from those in the photos of the test kits. If anyone happens to know, off-hand, what size the test vials are, I would greatly appreciate the info, for accuracy's sake. I'd just go ahead and order the kit, but this took a few weeks in shipping(no fault to the postal service; it's just the times we're living in right now. Thanks for a great product that is far more reliable than my constantly-needs-calibrated digital ph meter! Namaste
