The Dymax RX-123 DC CO2 Regulator is a CO2 regulator with a low-heat DC solenoid for accurately controlling CO2 injection into freshwater and saltwater aquariums.

Key Features

  • High accuracy
  • Hand-tightened to the cylinder — no tools needed
  • Lightweight, corrosion-resistant aluminium
  • Low-heat DC solenoid, multi-directional

Good To Know

  • Plants only use CO2 in light; switch it off at night (a solenoid on a timer does this automatically).
  • Start with a low bubble rate and increase slowly over a few days while you watch the fish.
  • After fitting, brush soapy water over every joint; bubbles mean a leak that needs re-tightening.
  • Fit a check valve between the regulator and the tank.
  • Keep CO2 cylinders upright, secured and away from heat and direct sun — never leave one in a hot car.
