Flow rate controller for a precise CO2 supply. When one source of CO2 is branched off, each line needs a separate Speed Controller. Please use Speed Controller in case of supplying less than 1 bubble per second. Speed Controller G is used for over 1 bubble per second.

Some types of Speed Controllers and Hand Valves have a specific direction for connection. Please follow the above sign and make sure to connect correctly.

Easy On-Off CO2 flow switch by turning the handle. Ball Valve G has a larger handle for easy operation. Ball Valve is small, and barely-noticeable. You can select from two different colors.

For connecting Pressure-resistance tubes for CO2 supply. Joint Stick is also used with silicone tube. Stop Cap is used with Joint Stick for stopping the hole of branch that is not in use.

CO2 pressure gauge for checking the level of CO2 pressure inside distribution tubes. Connect the tubes to both ends and stop the flow of CO2. Then, measure the pressure.

Joint parts used for delivering CO2 to multiple distributing lines. It is used when supplying CO2 into several aquarium tanks from large CO2 bottle, or placing multiple diffusers with a large tank in order to improve diffusion efficiency.

A set of accessories (suction cups, silicone tube, check valve) for the installation of glass products of CO2 distribution. Please replace check valve every year. It is recommended to replace silicone tube at same time.

Clear Parts Set is the clear transparent type of Parts Set. The contents of the set is same as Gray parts Set that are necessary for connecting and installing glass-made equipment. It is recommended to replace Suction cups and Check valve approximately once a year as the suction capability of Suction cups decrease with time, and Check valve degrade with age and triggers counter flow to EL Valve and CO2 regulator, causing the breakage.

Neatly and efficiently organize 2-4 Pressure Tube lines. In case of multi CO2 addition, tube arrangement becomes a mess, but it is possible to make neat arrangement by Tube Holder.

It is used for the connection between CO2 Regulator and Check Valve. This tube is also good for connecting the joint parts. Do NOT connect it directly to the glass products.
