Description

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 dosing for your aquarium. A drop checker removes the guesswork.

The solution in the drop checker changes colour 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 colour 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 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.

Instructions

  • Turn drop checker up-side-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 area of aquarium where CO2 bubbles from the diffuser will not enter the drop checker and give inaccurate readings.
  • Wait at least 6 hours for colour to accurately reflect the CO2 levels in the aquarium.
  • Adjust CO2 dosing in accordance to drop checker colour:
  • If the colour of the solution is yellow it indicates too much CO2 is present - reduce your CO2 dosing.
  • If the colour of the solution is blue increase CO2 dose in small increments.
  • If the colour is a light green you have the correct CO2 dosing.
  • Leave drop checker in aquarium for constant CO2 monitoring.
  • Change drop checker solution at least once every 4 weeks.

Compact design means it's easy to hide away but big enough so you can easily see the colour. It's very useful for getting CO2 levels adjusted to the correct level.
