Description

Incredible function, design and manufacture - the Ultimate-Pro Dual Stage CO2 Regulator with 12v DC solenoid gives the highest performance possible.

The dual stage mechanism ensures the output pressure does not increase, even if input pressure increases or decreases, as can happen during the lifespan of the CO2 cylinder. This gives you peace of mind that the pressure and flow will always remain at the level you have set it to.

The adjustable output pressure ensures the regulator can meet the needs of any aquarium, whether it's a small nano aquarium of just 20L or an aquarium of 3000L that requires multiple diffusers, this regulator can deliver the pressure that's needed.

The regulator comes with a high performance advanced 12v DC solenoid valve fitted as standard. It guarantees safe operation, low power consumption, cool operating temperature and eliminates the possibility of any buzzing sound. The addition of the solenoid enables the regulator to be connected to a timer plug or pH controller so that the dosing of CO2 can be controlled. This enables the flow of CO2 to be shut off when the aquarium lights are not on and the plants aren't photosynthesising and do not benefit from the addition of CO2.

A high-precision needle valve is fitted as standard, which provides a very high level of accuracy of CO2 dosing. Dosing can be achieved as low as 1 bubble / 10 seconds, to a constant flow of CO2, enabling it to function for small nano aquariums of 20L to large aquariums of several thousand litres.

Instructions

  • Tighten the regulator to your CO2 cylinder using a spanner or wrench. Do not use your hands to tighten, it will not create sufficient seal and be likely to leak.
  • Set the output pressure to minimum by turning the pressure adjuster knob fully anticlockwise.
  • Close the needle valve by turning fully clockwise.
  • Plug the solenoid into a mains socket and switch on.
  • Open the flow of gas from your CO2 cylinder.
  • The cylinder presure gauge will now indicate the pressure of the cylinder. Turn the pressure adjuster clockwise until it reads 40PSI, which is a good starting point for a single diffuser installation.
  • With the bubble counter attached, turn the needle valve anticlockwise to achieve the bubble rate desired. 1 bubble / second is suitable for a 150L aquarium - adjust your dosing in accordance to this, i.e. 2 bubble / second for 300L aquarium.

I ended up being an awkward customer but Martin from CO2 Supermarket was very helpful and patient. As far as the equipment I ordered it’s all great quality and well priced.

Been in use for a few weeks now and the pressure and flow has remained exactly where I set it. This is proper medical-grade standard! Been in use for a few weeks now and the pressure and flow has remained exactly where I set it. This is proper medical-grade standard!

I bought this after being badly let down by a regulator I bought from another brand, who shall remain nameless, and nearly lost all my fish when it suddenly dumped a ton of CO2. Unfortunately there was a couple of casualties. I wish I'd got it from here to start with, it is so much better quality. I'm sure I'll be buying more from co2 supermarket in future.

Really good regulator and fast delivery Really good regulator and fast delivery
John L. Verified Buyer 16th Aug 2023
This regulator was part of the Ultimate-Pro CO2 system and has performed flawlessly in the couple of months I've used it. I've had zero drift on pressure or flow in that time and the solenoid has switched on and off without a problem.
