The indicator works well and clearly shows CO2 levels. I can see the color change from blue to green within a few hours after adjusting my CO2 dosing. It helps me maintain a stable environment for my fish.

Easy to use and reliable. I noticed the color shift when my CO2 was too high, which helped me adjust the dosing. It’s a simple but effective tool for monitoring.
