This professional grade CO2 System with ph & CO2 Controller (not just a monitor) is our most advanced setup designed with convenience in mind, providing you with fully automated system that will disperse CO2 for your plants to the exact desired levels while ensuring safety for all your aquarium fish and inhabitants by keeping ph levels steady at all times. This system, unlike others, will turn itself On and Off as needed based on the water parameters, so you can enjoy your aquarium without added work and without dangerous fluctuations of both, PH and CO2.

The setup comes complete with:

Aluminium 5 lb. CO2 Cylinder

This aluminium CO2 cylinder has a 5 lb capacity and is extremely efficient. Made of highly corrosion-resistant these cylinders meet or exceed all regulatory standards worldwide and are relatively lightweight compared to other cylinders.

*Cylinder colors might vary between Silver and Chalk Gray.

Dual Stage CO2 Regulator Kit with Solenoid Valve and Bubble Counter

Unlike "Single Stage", this Dual Stage CO2 Regulator comes with a Dual Stage Valve for added safety and reliability.

This added safety mechanism dramatically reduces the chance of accidentally changing CO2 output volume.

This professional grade aquatic Dual Stage CO2 controller kit also comes ready with bubble counter, extra regulator seals and electromechanically operated on/off solenoid valve that can be used with a ph controller or timer.

Milwaukee PRO ph & CO2 Controller

This pH controller measures your aquarium ph and also automatically controls it by turning your CO2 on and off when connected with your CO2 Regulator's Solenoid Valve (hint: CO2 lowers ph).

Its job is two-fold;

1 - keep ph at steady levels all the time.

2 - control the amount of CO2 your plants receive, allowing for their optimal growth without dropping ph levels to dangerously low levels for your fish.

Premium CO2 Tubing

This 8 foot long Black Premium Silicone Airline Tubing is constructed to resist kinking, hardening and breakdown.

27mm Glass Diffuser 

Diffuser is a highly effective way to disperse CO2 throughout your planted aquatic system.

The sleek, low profile of available diffusers helps to minimize visual distractions within the tank.

Suction cups included with each unit.

Glass U-Tube (20mm)

The 20 mm wide Seachem Glass U-Tube is a convenient addition to any CO2 setup.

The incredibly sturdy and durable glass u-tube allows aquarium owners to easily run an airline for CO2 supply over the rim of an aquarium to ensure that there are no potentially damaging kinks, bends or creases in the hose.

The strong clear glass helps to minimize the visibility of the tubing and is well suited for most rimless and standard aquarium rims.

    Great product. Easy to calibrate.

    Great product easy to calibrate. Just I wish there was a clearer instructions for first turning the system on as I had the valves mis adjusted when I opened the cylinder valve and exploded the diffuser, but that was my fault, It would help others first time set up to explain the valves a little more

    the service was fast and hassle free. The supplied product was exactly as described and works great. Some simple setup instructions would have been nice but was easy to research online

    I just wish it came with a training video on how to set up and what to Expect when set up and what all the numbers mean.
