About this product
This DIY CO2 kit for aquarium use is the Clscea G211, a set built around a 4 in 1 CO2 diffuser that also counts bubbles. The diffuser carries its own check valve, and a metal needle valve lets you set the output to 4 to 5 seconds per bubble. The kit is fed from a carbonated beverage bottle, and no other bottle type should be used with it.

Which bottles can you use with this CO2 kit?
Carbonated beverage bottles are the only bottles the kit is meant to run on, and the manufacturer states that other bottles should not be used. Check your bottle type before you set the system up, because the connection is designed around that kind of bottle.
How to start and run the kit
To start the reaction, shake the starting tube and wait until the gauge shows the green pressure range. Once the pressure sits in that range, the system is running.
Adjust the metal needle valve to a bubble every 4 to 5 seconds. That valve sets the output volume only and needs to be set once; day-to-day switching on and off is done with the white on/off valve instead.
The diffuser, the valves and what each part does
The 4 in 1 CO2 diffuser releases the gas into the tank and counts the bubbles, so the same unit shows you the rate you set at the needle valve. A check valve is built into the diffuser.
The metal needle valve gives the fine adjustment, at 4 to 5 seconds per bubble. A pressure relief valve is fitted as well, and the white on/off valve handles the daily on and off switching.
What rate should the bubble counter be set to?
How many seconds should pass between bubbles?
The needle valve adjusts to 4 to 5 seconds per bubble.
Do I need to change the needle valve setting every day?
No. The needle valve sets the output volume and only needs to be adjusted once; daily switching is done with the white on/off valve.
Does the diffuser include a check valve?
Yes, the 4 in 1 diffuser has a built-in check valve.
What kind of bottle does the kit take?
It runs on carbonated beverage bottles, and the manufacturer states that other bottles should not be used.
How do I know the pressure is in the right range?
Shake the starting tube and wait until the green pressure range is reached.
