Easy to use and very reliable. I filled it according to instructions and the deep green color confirmed my CO2 levels were just right. No need to mix anything. Works well with my planted tank.

It’s simple and effective. I’ve used it for three months now and it still gives clear readings. The only thing is it’s a bit tricky to mount without spilling, but once set, it’s stable.

Great product for beginners. The instructions are clear and the color change is noticeable. I can now adjust my CO2 without guessing. Definitely worth the small investment.
