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.

Super well-built and feels incredibly sturdy. I’ve been using it for a couple of months now, and there's been no pressure or flow drift, and the solenoid switches on and off perfeclty each morning and night. It's definitely a great investment and highly recommended! Super well-built and feels incredibly sturdy.

I bought it for the dual stage aspect to protect against end of tank dumps, and the build quality is top-notch, and setting the pressure is smooth and reliable and the 12v solenoid means its absolutely silent.

Came as part of the kit. This is my first co2 system so I don't have anything to compare to but it certainly seems like a great piece of gear. It's got a good weight to it and certainly seems like good quality. Came as part of the kit.

First time using CO2 was a bit nervous as my 250l tank is well settled not overly stocked or overly planted, wanted to add another dimension with the standard planting. Wanted some nice carpet plants etc. We have all seen these scapes and deep down we all want one!!! Only set up today thus far bubbling nicely. Everything I ordered came packaged well and felt like quality once opened, instructions and read more...

Seems like a very capable regulator and very good quality. Its been in use for a couple of weeks and there's been no change to the pressure or flow I set.
