Usage Tips

Things to Note:

1. The motorized valve may make a soft sound when turning on/off — this is normal and not a fault. It runs quietly during normal operation.
2. Soak the diffuser in your aquarium for 24 hours before use. If bubbles aren’t released right away, wait briefly due to low initial air pressure. If problems continue, check tube connections for leaks.
3. The motorized valve is not waterproof. Avoid contact with water to prevent damage.
4. Baking soda and citric acid are not included and need to be purchased separately.

Raw material addition ratio:
2L capacity: 200g citric acid+200g baking soda+ 300mL water
5L capacity: 600g citric acid+ 600g baking soda + 900mL water

Simply add baking soda, citric acid, and water to the cylinder, close the valve, connect the accessories, and start providing your aquatic plants with the CO2 they need.

Usage Tips:

1. Do not add excessive amounts of raw materials or water; do not shake or invert the bottle during the reaction.
2. Water condensation may occur at the bottom of the bottle during the reaction, which will disappear after half an hour.
3. Do not invert or tilt the cylinder. Do not use strong acids or bases.
4. Ensure the pressure has returned to zero before opening the valve.
