DYMAX CO2 PROFESSIONAL REGULATOR RX-123

Dymax CO2 Professional Regulator RX-123 is a single-stage CO2 regulator for precise CO2 injection into planted freshwater or reef aquariums.

• Lightweight, corrosion-resistant aluminum body
• Hand-tighten connection — no tools required to mount on a CO2 cylinder
• Multi-directional solenoid
• Runs cool — low heat generation during operation

A hand-tight cylinder connection means swapping or refilling a CO2 tank doesn't require a wrench or a trip to a shop with the right fitting — useful for anyone running their own pressurized CO2 setup at home, and the multi-directional solenoid gives more flexibility in how the regulator is oriented on the tank compared to a fixed single-position design.

Compatible with: Standard CO2 cylinders; suitable for both freshwater planted tanks and reef aquarium CO2/calcium reactor setups.
