Dual Stage CO2 Regulator Kit w/ Solenoid Valve & Bubble Counter

If you want steadier CO₂ delivery and fewer “surprise swings,” a dual-stage regulator is the upgrade that matters. Unlike single-stage regulators, this Dual Stage CO2 Regulator Kit uses a dual-stage valve design for added safety and reliability—helping reduce the chance of an unintended change in CO₂ output as cylinder pressure drops.

Product Overview

This professional-grade aquatic CO₂ regulator kit is built for planted aquariums where consistency is everything. It includes an electromechanically operated on/off solenoid valve (perfect for a pH controller or timer), a bubble counter for dialing in your bubble rate, and extra regulator seals to keep your setup running smoothly over time.

Constructed from heavy-duty materials, it’s designed to be dependable for daily planted-tank use and also works well for calcium reactor applications where stable CO₂ delivery is equally important.

A clear dual-gauge display allows you to monitor both cylinder (canister) pressure and CO₂ output pressure, so you can see what’s happening in your system at a glance and make precise adjustments with confidence.

Key Features:

  • Dual-stage reliability: Added stability vs. single-stage regulators to help prevent unintended CO₂ output changes.
  • Controller/timer-ready solenoid: Automate CO₂ on/off with a pH controller or timer for more consistent daily dosing.
  • Bubble counter included: Makes it easy to set and monitor your bubble rate.
  • Heavy-duty build: Designed for dependable long-term use in planted aquariums and calcium reactors.
  • Dual gauges: Monitor cylinder pressure and output pressure at a glance.
  • CO2 tank not included.

Together, these features give you a more stable, professional CO₂ foundation—especially for high-growth planted tanks where consistency is critical.
