It can be difficult to keep an aquarium healthy, particularly when it comes to adjusting the water’s parameters. Maintaining the proper concentration of carbon dioxide (CO2) in the water is one of the most important things you can do to keep your fish and plants healthy. Both fish and plants can experience issues with excessive or insufficient CO2, which can impact their growth and general well-being.
For any aquarist, this is where a drop checker comes in handy. You can keep an eye on the CO2 levels in the water in your aquarium by using a drop checker, which is a basic but useful tool. A drop checker makes it simple to make sure that your aquarium has just

Application and principle of operation
After adding indicator liquid to the drop checker, the aquarium water is added. Additionally, the drop checker aids in determining the liquid’s content because it is saturated with an amount of carbon dioxide that is currently unknown.
In actuality, the aquarium environment absorbs carbon dioxide (CO2) from the surrounding air. CO2 enters the aquarium from regular air and dissolves quickly and easily in the water. Naturally, water CO2 saturation is limited to the point at which the gas’s equilibrium content is reached in both contacting media.
The amount of CO2 in the air is roughly 3 mg/l, which is the same as what is present in regular water from the crane. This level of carbon dioxide is insufficient for both plants and aquarium fish, so additional CO2 must be added to aquariums to maintain normal conditions for the native flora and fauna.
It returns fairly quickly because there is less gas in the air the more gas there is in the water. Dropkens operate on the same principle of preserving gas equilibrium.
For instance, water will have a higher CO2 content after being saturated with carbon dioxide. Simultaneously, the device’s part maintains its same content, which is an equivalent atmospheric concentration.
An equilibrium will be reached between the gas concentration in the aquarium and in the air zone of the tester once it is submerged in the water. Since the process is weathering, it doesn’t proceed too quickly.
One tool that can be used to measure the amount of carbon dioxide in water is a drop checker.
Evaluation of the result
When the gas that has passed through the water dissolves in the device’s air zone, as indicated by the indicator, you can view the test result. A small amount of the same CO2 is present in the indicator liquid and enters through the air-filled portion of the tester. As the gas dissolves in the indicator, it changes the liquid’s color and makes its hydrogen index equal to that of water.
The color shifts smoothly, allowing you to distinguish between various shades and an accurate estimation of the CO2 content of the water.
Since a drop checker has a relatively high moment of inertia and only measures the gas content of the aquarium water that was present 0.5–1.5 hours ago, it is not advised to use one for an accurate assessment.
The amount of gas in the liquid is reflected in its color:
- when you see blue, you know that CO2 is less than 10 mg/l;
- green – within 10-25 mg/l;
- yellow – gas in the water is more than 330 mg/l.
Any aquarist who wishes to keep their aquarium environment balanced and healthy must have a drop checker. It assists in keeping an eye on the water’s carbon dioxide (CO2) levels, which are vital to fish and plant health. A drop checker makes sure your aquarium has the proper amount of CO2 for healthy plant growth while avoiding unhealthy conditions for fish by giving you access to real-time CO2 levels. This little device can go a long way toward maintaining the health and vibrancy of the ecosystem in your aquarium.
Features of choice
It’s critical to keep the CO2 level within a certain range for the aquarium to operate normally. Your fish’s life is in danger if the CO2 level is exceeded; a significant drop will cause plant growth to slow and algae to appear. A long test, or drop checker, is a tool used to track carbon dioxide levels.
Remember that the drop checker’s standard design operates more quickly than other designs. The use of only premium indicator liquid is a prerequisite. And low-cost, questionable-quality options frequently yield misleading outcomes.
Let’s look at a few possible options for purchases.
- for example, the company AQUAYER produces good drop checkers of standard design, reacting within 30 minutes;
- also worth paying attention to testers from VIV, which are products made of high-quality glass.
Nonetheless, you can build this device yourself if you want to save costs while still getting precisely the features you require.
| Why Use a Drop Checker? | Benefits for Aquarists |
| Monitors CO2 Levels | Helps maintain the right balance for plant growth and fish health. |
| Prevents CO2 Overdose | Avoids harmful conditions that could stress or kill fish. |
| Easy to Use | Simple color changes indicate CO2 levels, making it accessible for beginners. |
One easy way to make sure your aquatic plants have the proper amount of CO2 in their environment is to use a drop checker in your aquarium. You can foster a healthy environment for fish and plants by keeping an eye on CO2 levels. This will lower the likelihood of algae issues and encourage vibrant growth.
CO2 dosing becomes less of an artifice when a drop checker is utilized. It helps you keep the ideal balance easier by enabling you to quickly determine whether adjustments are necessary. For newcomers who are still learning how to control the CO2 in their tanks, this tool is extremely helpful.
