PRO-SE Series - New Generation of our most popular Aquarium Dual Stage CO2 Regulator from CO2-Art. 

Completely redesigned with new pressure stabilisation construction. Much larger internal springs are giving safety and precision at the highest level.

Dual stage design minimise increase in output pressure as pressure drops in gas cylinder and will prevent end-tank-dump keeping your aquarium livestock safe and CO2 levels constant.

  • New quality design and completely new construction.
  • Includes black bubble counter
  • Innovative design provides extreme accuracy and safety.
  • Integrated Solenoid Valve.
  • Adjustable working pressure up to +/- 40PSI (3 BAR) which makes excellent product for both Tropical and Marine Aquariums.
  • Dual gauge pressure indicators (tank volume and flow pressure / working pressure)
  • Due to Two Stages construction compatible with any size CO2 Cylinders.
  • The thread is made according to UK, Europe, Japan and Taiwan standard (BS341 / DIN477 / W21.8)
  • Compatible with all types of diffusers including in-line and bazookas.
  • Standard UK 3 Pin Plug.

Included with the regulator is a magnetic solenoid valve. This is a superb piece of equipment that allows you to shut off the CO2 into your aquarium during the "lights off" period when your plants don't need CO2. This prevents CO2 wastage, saves you money, and time is saved as the CO2 can be automatically shut off using a timer rather than manual intervention. Attach the Solenoid to an electric plug timer in order to automate the CO2 coming ON/OFF. 

Pro-SE Series Regulator at a Glance

A - CO2 cylinder connection nut
B - Working pressure adjustment knob
C - High pressure / CO2 cylinder pressure gauge (displays the amount of CO2 in your cylinder). Please note, for most of the time pressure will be at level of 700-900PSI as CO2 is in liquid state. When gauge will start to drop, that means liquid gas has evaporated and you have from couple hours to couple of days left to change the cylinder (depending on your bubble rate).
D - Low pressure / working pressure gauge
E - Bubble counter with integrated check valve
F - Gas flow (bubble rate) adjustments precision needle valve
G - Solenoid valve compatible with most pH controllers and electric timers

Step 1 | Washer Installation

Place washer between CO2 cylinder outlet and regulator's stem (inside regulator's nut)

Step 2 | Tighten the regulator

Tighten the regulator to your CO2 cylinder using a spanner or wrench

Step 3 | Bubble counter installation

A - Remove top cap and fill bubble counter with water*
B - Feed tubing through the collar and install cap back onto the bubble counter (detailed bubble counter tutorial)
*We do not recommend mineral oil as it may contaminate your diffuser.

Step 4 | Pressurising the regulator

A - Open main CO2 cylinder valve
B - Adjust working pressure to desire level* by turning front knob clockwise
1 - Reactors 10-20PSI*
2 - Ceramic and Basic diffusers 20-30PSI*
3 - High pressure atomizers (inline & bazooka) 30-40PSI*

Step 5 | Fine tuning bubble rate

A - Plug the solenoid into a power outlet socket
B - Start turning the needle valve anticlockwise to achieve the desired bubble rate.
Please allow 5-30seconds for pressure to stabilise between adjustments.
Monitor your bubble rate for the first two days and fine tune to achieve desire flow.
Do not adjust the flow right after solenoid is powered up. Please wait at least 30minutes before further adjustments. 
After each regulator installation, follow steps from below video to make sure your system is leak-proof.

Co2 Regulator

I bought this regulator to replace an elderly Dennerle unit that was unreliable. First impressions are very impressive unit, well packed at the factory and by Aquarium Gardens. Straight forward installation and setup. Easy to regulate and achieve the correct gas flow rate. First morning after installation my indicator is nearly clear and co2 ppm through the roof. Fish gasping for oxygen. The solenoid had turned off but the needle had not sealed enough to close off the gas! No responce from AG to my contact email! A Google search came up with some solutions so I have rectified this now. Not what you expect from a quality product.
