Collection: CO2 Regulators & Packages

Pressure Control Is the Whole Job

CO2 leaves the cylinder at extremely high pressure. The regulator brings that down to something a diffuser can use, and the needle valve doles it out bubble by bubble. Mismatched parts are how you end up with either nothing dissolving or a sudden dump overnight.

Package or Standalone

• Complete packages — cylinder, regulator and needle valve together, with fittings that are known to work as a set.
• Solenoid packages — an electric shutoff so CO2 stops when the lights go off, saving gas and preventing a night-time pH swing.
• Standalone regulators — dual-gauge models reading cylinder and working pressure, plus electronic options for precise control.

Running CO2 on a timer? Buy the solenoid version up front rather than adding one later. Questions? Email sales@jlaquatics.com.
