I’ve used these strips for three months now and they’re very reliable. The color chart is easy to read and the results match what I see in my digital meter. Great for weekly checks in my freshwater tank.
Natalie MacDonald –
The strips come in a sealed tube, which keeps them dry. I found the instructions clear and the pH range covers what I need for my community tank. A small improvement would be a more visible color chart, but overall very useful.

I switched from digital testers to these because they’re cheaper and easier to use. The desiccant tube keeps the strips fresh, and I get consistent results every time.
