FAQ:

Q: How does a CO2 diffuser work in an aquarium?

A: CO2 diffusers take the gas produced by your injection system and mix it with water to make fine, microscopic CO2 bubbles. As the bubbles float in your aquarium, the CO2 is dissolved into the water column, where your plants can take up and utilize it.

Q: How much is an inline CO2 diffuser on Amazon?

Q: How does a gas diffuser work in a plant?

A: A gas diffuser works by increasing the surface area of the water exposed to CO2. It does this by slowing feeding the gas through a ceramic disc, which distorts the water and ensures that carbon dioxide remains in circulation for plant conversion to oxygen. You can check this video to learn more about the CO2 diffuser.

Q: Which is the best material for a CO2 diffuser?

A: While glass is the most common material in CO2 diffusers, stainless steel might be a better option if you’re particularly clumsy. They aren’t as attractive, but they also don’t break as easily. Diffusers made from glass-like resins are stronger and more durable as well.
