RWBO - 500g not refillable CO2 bottle

RWDI - CO2 diffuser with ceramic disc Ø 26 mm

This CO2 diffuser can be completely disassembled for regular cleaning or for replacement of the ceramic disc. RWDI CO2 diffuser also operates as bubble counter.

RWRP - CO2 regulator

This professional unit includes a fine regulation valve and a non-return valve.

The RWRP CO2 regulator can be also used with a refillable CO2 bottle by simply using the adapter RWAD.

RWEV- solenoid valve.

This solenoid valve can be used for automating CO2 diffusion using a timer or pH controller. It is provided with 2 safety connectors for CO2 tubing.

RWAD - adapter for CO2 refillable bottles

This adapter allows use of the CO2 regulator RWRP with any kind of standard refillable CO2 bottles (CO2 outlet: 3/4").

RWNR - non-return check valve

It must be used when there is no non-return valve already assembled to the CO2 regulator.

The non-return check valve must be placed between the CO2 bottle and the CO2 diffuser if the system is manually controlled. If the system has been automated using a pH controller, it must be placed between the solenoid valve and the CO2 diffuser.

RWRE - CO2 reactors

CO2 reactors RWRE must be connected to a circulation pump and provide the best way for a perfect mixing of water and CO2. They are available in 2 models (17 and 28 cm high).

Precision bubble counter with non-return check valve

RW CO2 TEST - CO2-Long Term Indicator

CO2 is the most important water plant nutrient.The plant will not grow in unsufficient Carbon Dioxide condition, but it will be harmful to fish in high concentration of CO2. This shows the correct concentration of CO2 is very important. To predict the concentration of Carbon Dioxide by counting the releasing bubbles cannot reflect the scientific accuracy. This way always taken by those who have lot of experience in aquarium plants is not suitable to most hobbysts and beginners.
CO2-LONG TERM INDICATOR can easily read the actual concentration of CO2 just by colour change of solution in long term. CO2-LONG TERM INDICATOR offers the best suggestion to CO2 addes way

RWRP/PRO - Professional CO2 Regulator

This professional CO2 regulator is provided with 2 gauges and a non-return check valve.
It can be used with any size of refillable CO2 bottle.

RW CO2 TURBO KITS

RW CO2 Turbo Kits are the best solution for CO2 diffusion in fresh water aquariums.
By using standard CO2 diffusors with ceramic disc it is not possible to mix totally the given CO2 with the aquarium water, because some of CO2 bubbles will inevitably be lost when arriving to water surface, even if CO2 diffusor is placed near a pump outlet.
With RW CO2 Turbo Kits CO2 and water are already mixed together inside the impeller’s chamber of the pump. In this way 100% of given CO2 will be added to the aquarium water
Moreover, the adjustable water outlet of the pump will allow a better and more homogeneus distribution of CO2.
RW CO2 Turbo Kits are provided with a practical precision bubble counter, which can be placed both internally (Operation Diagram A) and externally (Operation Diagram B) to the tank.
RW CO2 Turbo Kits are available in 3 models:

• CO2 TURBO KIT 1 – mixing pump RIO 200 for aquariums up to 70 cm
• CO2 TURBO KIT 2 – mixing pump RIO 400 for aquariums up to 100 cm
• CO2 TURBO KIT 3 – mixing pump RIO 600 for aquariums up to 160 cm

For aquariums bigger than 120 cm it is suggested to use 2 kits.
