• Regular size glass drop checker and suction cup.
• Pre-mixed drop checker solution using 4dKH water.
• Accurately monitor CO2 levels in your aquarium.
• Changes color to reflect CO2 levels.
• Removes guesswork of how much CO2 is required.
• Easy to use and install

INSTRUCTIONS

• Turn the drop checker upside-down so that the curved bend is at the bottom.
• Add 5 drops of drop checker solution.
• Slowly rotate the drop checker so that the solution enters the bulb.
• Repeat the above steps until the bulb is 2/3 full of the solution.
• Attach the suction cup to the drop checker.
• Press the drop checker inside the tank 3 inches below water level, ensuring you have air trapped inside the main body of the drop checker.
• Try to position in an area of the aquarium where CO2 bubbles from the diffuser will not enter the drop checker and give inaccurate readings.
• Wait at least 6 hours for the color to accurately reflect the CO2 levels in the aquarium.
• Adjust CO2 dosing in accordance to drop checker color:
• If the color of the solution is yellow it indicates too much CO2 is present – reduce your CO2 dosing.
• If the color of the solution is blue increase the CO2 dose in small increments.
• If the color is a light green you have the correct CO2 dosing.
• Leave drop checker in the aquarium for constant CO2 monitoring.
• Change drop checker solution at least once every 4 weeks.

Descrption:
A drop checker is an essential part of dosing CO2 in your aquarium. Without one, you would be guessing at how much CO2 you should be doing for your aquarium. A drop checker removes the guesswork.

The solution in the drop checker changes color to indicate the level of CO2 in your aquarium water; blue indicates a lack of CO2, yellow indicates too much CO2, and green indicates the desired level of CO2. Depending on the color of the drop checker you can adjust your CO2 dose until the desired level of CO2 is reached.

The drop checker should be used in conjunction with a bubble counter so that fine adjustments to CO2 dosing can be achieved. Always make small changes to CO2 dosing, particularly if increasing the dose.

The kit includes a pre-mixed drop checker solution, which is added directly to the drop checker. The solution comes in a 15ml dropper bottle for ease of use. The solution will last 6 months if changed on a monthly basis.
