CO2 Concentration Checker

If there is too much CO2, the baby fish will die.

If there is less CO2, the water plants will not be in good spirits

Music CO2 monitor

1. Hold the monitor mouth vertically upwards

2. Drop in the monitoring liquid, the dose is enough to reach about 1/2 of the glass sphere

3. Rotate the monitor in the direction as shown in the diagram, and let the monitoring liquid flow into the sphere, if the inflow is not smooth, you can gently shake or flick the monitor sphere.

If the inflow is not smooth, you can gently shake or flick the monitor sphere

4. Put the monitor into the water vertically and fix it on the cylinder wall.

It is recommended not to fix the monitor above the CO2 refiner outlet.

Blue - low CO2 concentration

Green - moderate CO2 concentration

Yellow - high CO2 concentration

The color of the monitoring solution will gradually change according to the CO2 concentration, which usually takes a few hours.

If it keeps showing blue, please adjust the CO2 supply volume and then observe again after a few hours until it reaches green as the best condition.

The color is a slow and gradual process, it is recommended that each time you adjust the CO2 output not to exceed 50% of the output volume, to avoid excessive oxygen deprivation of fish and shrimp.
