DICI Pro Series: Ultimate Dual-Stage Aquarium CO2 Regulator with Silent Solenoid and Integrated Bubble Counter

Every DICI 100-series Dual Stage Regulator is built to industrial standards, combining high-grade materials with CNC-machined precision.

Why "Dual Stage" is the Professional Choice

When you invest in rare aquatic plants like Bucephalandra, Eriocaulon, or high-tech carpets, your equipment must be as resilient as your passion. Here is how the DICI Dual Stage stands out:

2.1 Elimination of "End-of-Tank Dump" (EOTD)

This is the single most important safety feature for any professional aquarist. While single-stage regulators rely on the cylinder's internal pressure to stay stable, our Dual-Stage design reduces the high tank pressure (approx. 800-1000 PSI) to a stable middle-stage pressure, and then to a final, controllable working pressure. Even as your cylinder empties, the output pressure remains identical, protecting your fish and shrimp from lethal CO2 spikes.

2.2 Whisper-Silent DC Solenoid Valve

Heat and noise are the common enemies of a living room aquarium. Our proprietary 12V DC Solenoid technology operates at a significantly lower temperature than traditional AC models. It is completely silent—no buzzing or humming—and is designed for over 50,000 hours of continuous operation. It can be easily automated with a standard timer or pH controller.

2.3 Surgical Precision Micro-Adjustment Needle Valve

The heart of our gas control system is the ultra-fine needle valve. Designed for high-resolution dosing, it allows for adjustments as granular as 1 bubble every 10 seconds. This level of control is essential for nano planted tanks where even a minor overdose can cause a pH crash.

2.4 Integrated Security: 2-in-1 Bubble Counter

Every DICI regulator comes with an integrated aluminum bubble counter. It features a built-in check valve to prevent aquarium water from back-siphoning into the regulator's internal electronics. This prevents corrosion and ensures the long-term longevity of your investment.

Versatility Across the Hobby

The DICI Dual-Stage Regulator is a versatile powerhouse optimized for several high-demand aquatic environments:

Professional Aquascaping Competitions: Used by world-class scapers to maintain the perfect 30ppm CO2 saturation for high-demand plants like HC Cuba or Rotala Macrandra.

Shrimp & Sensitive Livestock Tanks: The constant pressure output ensures that pH levels do not fluctuate, which is critical for the survival of delicate species like Crystal Red Shrimp (CRS).

Marine Calcium Reactors: Its precise, low-volume output makes it a reliable choice for reef keepers who need to accurately dose CO2 into calcium reactors to maintain alkalinity and calcium levels.

Dutch-Style Planted Tanks: Provides the heavy, consistent CO2 flow needed for massive stem plant growth without the risk of "pressure drift" during the day.

The DICI Advantage

In a closed aquarium system, plants rapidly deplete natural carbon sources. Without supplementation, photosynthesis stalls and algae takes over. The DICI Dual Stage provides a steady stream of carbon, allowing your plants to achieve the famous "Pearling" effect—where they release visible bubbles of oxygen. By maintaining a stable CO2 concentration, you create an environment where plants out-compete algae for nutrients, leading to a crystal-clear, healthy display.

The DICI Valve Commitment

Choosing DICI Valve means choosing over 15 years of engineering excellence in fluid control. We are a direct manufacturer specializing in professional-grade aquatic equipment for a global market.

Our Quality Philosophy:

Leak-Free Guarantee: Every single Dual Stage unit undergoes a 72-hour high-pressure static test and a solenoid fatigue test before it leaves our factory.

Industrial Material Selection: We use high-density aluminum alloy and chrome-plated brass to ensure our regulators can handle the pressures of food-grade CO2 cylinders safely.

Global Standard Support: We offer localized thread standards (CGA320, W21.8, G5/8) for all major markets, ensuring a "plug-and-play" experience without leaky adapters.

OEM/ODM Expertise: We are the preferred manufacturing partner for many of the world’s leading aquarium brands, providing custom engineering and private label services.

To ensure the longest lifespan for your aquarium CO2 system, follow these expert tips:

Correct Mounting: Use the provided high-density O-ring and tighten the nut with a wrench (do not over-tighten). Never use Teflon tape on the cylinder connection.

Solenoid Management: Connect the solenoid to your light timer. We recommend setting the CO2 to turn ON 1 hour before the lights go on, and OFF 1 hour before the lights go out.

Bubble Counter Maintenance: Fill the counter 2/3 with water or specialized CO2 indicator oil. Check the fluid level every few months.

Leak Testing: Periodically spray a small amount of soapy water on the connections to ensure a 100% gas-tight seal.

Q: Why is Dual Stage better than Single Stage? A: A Dual Stage regulator protects your tank from the "End-of-Tank Dump." It is the only way to ensure 100% pressure stability from a full tank to an empty tank.

Q: Can I use this with a paintball tank? A: Yes, with a standard CGA320-to-paintball adapter, the DICI Dual Stage works perfectly on portable paintball setups.

Q: Does it fit my local CO2 cylinder? A: We provide all major thread standards including CGA320 (US/Canada), W21.8 (Europe/UK), and G5/8 (Asia/Australia). Please specify your region when ordering.

Q: Is the solenoid replaceable? A: Yes, the modular design allows for easy maintenance. While our solenoids are rated for 10+ years of use, they can be easily serviced or replaced if necessary.
