Mr. Aqua's CO2 glass blown bubble counter comes with a glass hanger.
Counts Co2 bubbles dispensed in planted aquariums
Compact design, durable construction
3 suction cups included
Can be cleaned
Dimensions: 3/4 x 3/4 x 4 3/4
Instructions: When installing pressure pipes from the CO2 regulator, the pipe should be longer than the distance installed. Open the CO2 regulator slowly. A certain quantity wil first accumulate in gauge before starting to dispense. Determine the amount of CO2 required and pH value, add in the adequate amount of CO2 as needed.
To setup: Fill the counter with water. Connect the CO2 tubing to the inlet of the counter. CO2 gas from the pipe will create bubbles in the water. Count the number of bubbles per second to make calculation. Counter can be placed outside of the tank. Use the suction cups provided to attach it on the aquarium glass.
