Frequently Asked Questions

Q: What is an aquarium CO2 diffuser atomizer and how does it work?

A: An aquarium CO2 diffuser atomizer (also called a CO2 sprayer or reactor) uses a porous ceramic disc to break CO2 gas into extremely fine micro-bubbles. These tiny bubbles have a larger surface area, which allows CO2 to dissolve into the water much more efficiently before rising to the surface — delivering more usable CO2 to your aquatic plants.

Q: What materials is this CO2 diffuser made from, and what are the dimensions?

A: This CO2 atomizer diffuser is constructed from a ceramic and plastic composite. The ceramic disc is responsible for generating the fine bubble output, while the plastic housing ensures durability and a secure fit. The unit measures 7 × 2 cm, making it compact enough for most aquarium setups.

Q: Is this CO2 diffuser compatible with my existing CO2 system?

A: This diffuser is designed to be compatible with standard CO2 system tubing commonly used in pressurized aquarium CO2 setups. It connects easily to most standard-diameter CO2 tubing. We recommend checking your existing tubing diameter to ensure a proper fit before use.

Q: How do I clean and maintain this ceramic CO2 diffuser?

A: Over time, the ceramic disc may become clogged with calcium deposits or algae, reducing bubble output. To clean it, soak the diffuser in a diluted bleach solution or white vinegar for several hours, then rinse thoroughly with clean water and allow it to dry before reinstalling. Regular maintenance will keep it performing at its best.
