Fzone Co2 Glass Drop Checker

CO2 Drop Checkers are used for long-term monitoring of the CO2 levels in the aquarium. For optimal plant growth, it is important to know the CO2 level in the water column for the health of your fish and the plants.

Over dozing of CO2 will lead to the death of fish; under dozing will stun the growth of your plants. A CO2 reagent is filled into the CO2 Drop Checker, then affixed the checker to the glass under water. The solution will change the color according to the amount of dissolved CO2 in the water column.

Descent product. Only suggestion is to include an eye dropper to make it easier to fill the tube and reason for 4 star rating.
Easy to install works great

Does what I need it to do, seems to be working. (I did separate water tests that seem to give the same results) so I'd say it's doing it's job! looks cute in the tank so it's not really an eye sore. 10/10

The neck of the drop checker is so narrow that its hard to get the liquid in the bulb. I had to do it one drop at a time, and rotate the checker and shake it to get each individual drop (it needs 15) into the bulb so that it won't fall out when inverted...

As an aquarium enthusiast, I'm always on the lookout for new tools and accessories to help me maintain a healthy and thriving tank. The FZONE Aquatic CO2 Glass Drop Checker is a recent addition to my collection, and I'm very impressed with its performance so far.The drop checker is designed to help monitor the levels of CO2 in your aquarium, which is crucial for the health of your aquatic plants and fish. It's easy to install and comes with clear instructions, making it accessible even for beginners.What I appreciate most about this drop checker is its accuracy. It provides a clear and easy-to-read reading of the CO2 levels in my tank, which helps me make informed decisions about how much CO2 to add or adjust. The glass construction is also very durable and high-quality, so I don't have to worry about it breaking or cracking easily.One thing to note is that the drop checker does require some initial calibration to ensure accurate readings. This may take some trial and error, but once you have it set up correctly, it's very reliable.Overall, I would highly recommend the FZONE Aquatic CO2 Glass Drop Checker to any aquarium owner looking for an effective and reliable way to monitor CO2 levels in their tank. It's a great investment that can help you maintain a healthy and thriving aquatic environment for your plants and fish.

I love the value of the FZONE Aquatic CO2 Glass Drop Checker, the package comes with the drop checker solution which is great! My setup is mostly ADA (tank, light, aqua soil, lily pipes) except the CO2 drop checker which to me was kind of expensive ($65 including the solution). I went with a different brand and the sucker cup was not strong and caused a mess when the checker fell to the tank bottom. The sucker cup comes with FZONE is strong and works well. Not long after I set it up, the blue solution changed to green which was what I would expect.
