FAQ:

Q: What is the best CO2 regulator for aquarium?

A: I recommend S.T. International or the Fzone PRO Series CO2 regulators if you want the best for your larger, heavily planted aquarium. Anyhow, the pressure in the S.T. aquarium CO2 regulator is put under control by the reliable output valve and aquatic plants will receive steady Carbon Dioxide injections even in your absence.

Q: What is a dual stage CO2 regulator?

A: A dual-stage valve ensures that the output pressure from the CO2 cylinder remains constant as its content flows into the aquarium, even when the Carbon Dioxide is in a gaseous state. A CO2 regulator with a double stage valve reduces the pressure twice, providing more precise control over the dump of Carbon Dioxide in the aquarium.

Q: Is there an instruction manual for installing a CO2 regulator?

A: The S.T. International CO2 regulator comes without an instruction manual, but the whole assembly process is pretty much carefree, even if you were a beginner. Adjusting bubbles might require good finger and eye coordination but not for so long. Once you strike the mark, it remains stable.

Q: Do you need a CO2 regulator for a grow room?

A: Different kinds of CO2 regulators are capable of handling grow rooms that come in various sizes. Bear in mind that it is necessary to invest in a regulator that would allow you to comfortably handle the space that serves as your grow room.
