Review on Fluval A7551 CO2 Indicator Kit by David Pack
Normal product for low tech installation
After three tries the gauge stayed attached to the tank. The first two times he broke free and swam away. Finally, I scraped off the part of the aquarium where I placed the algae indicator and it stuck. After about 24 hours he registered the CO2 status. It works and is inexpensive, but the guide is still in its infancy. Overall I would recommend if you want to get a feel for the CO2 levels in a low tank setup.
- Sturdy construction
- Not sure
