Description

Incredible function, design and manufacture - the Ultimate-SE 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.

This regulator came as part of the co2 system I ordered and I think it's fantastic. Even for a novice like me it was so easy to install and use. This regulator came as part of the co2 system I ordered and I think it's fantastic. Even for a novice like me it was so easy to install and use.

It works good, but mine was missing an o ring and the usb adaptor was broken. It works good, but mine was missing an o ring and the usb adaptor was broken.

The O-ring (washer) used for the cylinder connection is clear, so it may look like it's missing but it is there.

I bought this after being badly let down by a dual stage regulator from another seller and this is much much better, I wish I'd bought this from the outset. The regulator itself is better made and finished, more accurate, and more reliable. This is by far the best regulator on the market and the price is very reasonable.

An excellent regulator that combines superb quality, high precision and for a very reasonable price. I have recommended this to others because it really is outstanding in every regard.

Excellent product. Paired with a refurbished 2kg fire extinguisher and a nano diffuser. Really easy to setup following the co2 supermarket guides and it is silent in operation. Packaging couldn’t have been better. You really do get what you pay! Couldn’t recommend Co2 supermarket more highly! Excellent product.

This is the best regulator I've used, everything to quality and easy to adjust with fine degree of accuracy. This is the best regulator I've used, everything to quality and easy to adjust with fine degree of accuracy.

Amazing quality and function and really easy to use, even for a novice like me. I decided to pay a bit extra for dual stage to eliminate any chance of EOTD.

Easy to set up, seems to be well made, only gripe is needle valve adjuster could be more sensitive apart from that, works very well and would recommend.

Needed a slight adaptation to fit my NZ 3kg cylinder (the regulator nut was 2mm too long). Easily done and otherwise very simple to set-up. Fantastic service and communication from CO2 Supermarket. Always risky buying things from the other side of the planet, but Martin made it very easy. Would highly recommend.
