Simple to use!
I have mystery snails and it’s important to keep the pH of the water at a certain level. This kit is a fast, easy way to make sure it stays where it should, and comes with pH up and down so you can correct it immediately.

Good test
Bit pricey but test works great. The ph up and ph down not working at all.

It works well and is a great product that is easy to apply. There is a test tube and indicator drops and a color chart for the test results. It's a little tricky when applying ph up or down. What it doesn't tell you in the instructions is when the test result is clear there is no alkaline which means you may want to apply a few drops of the ph up. If the test result is real blue there is plenty of alkaline in the water which means you may want to apply a few drops of ph down. You check the level again after a few hours to determine if you have achieved the test result you wanted. If not add a few more drops. I keep mine at the level of the mid section of the color chart.

Good value
I actually don’t have fish but I have a snail and I test the water once a week and this is so helpful in finding out if I need to add anything to the water to maintain it for his health.

Max pH 7.6, poor dosing guidelines
The scale only goes up to 7.6, so useless for a cichlid tank. The pH up/down instructions tell you how much to add, but not what the expected change is. My pH was high off the scale (blue), but there i no way to know how high or how much acid to add.
