    CO2 Components
CO2 (Carbon Dioxide) is useful both in freshwater and marine environments. 
In the freshwater aquarium, CO2 enhances your ability to successfully keep live aquatic plants.  As green plants photosynthesize, they utilize carbon dioxide. Without CO2, live aquarium plants will have a hard time thriving in the closed aquarium system.
In the marine aquarium, CO2 is used to lower the pH of calcium reactors effluent in order to dissolve hydro carbonate media into bio-available calcium molecules. Calcium is then utilized by corals and other marine organisms mainly for skeleton building.

CO2 Reactors & Diffusers
- Azoo CO2 Carbon Dioxide Diffuser : Highly-efficient at mixing carbon dioxide in water, Azoo CO2 diffusers are perfect for planted aquariums. Each CO2 diffuser consist of a ceramic diffusion panel, bubble counter, and a high-pressure non-return check valve. Considered one of the best CO2, carbon dioxide diffuser on the market.
- Aqua Medic CO2 Reactor 1000 : The CO2 reactor 1000 is a hermetically sealed unit for introducing CO2 into larger aquariums. Its robust mounting plate enables it to be mounted outside the aquarium or inside the cabinet.
- AquaMedic CO2 Reactor 500 : Secured to the inside of the glass its advanced design offers a very high CO2 diffusion rate and automatically removes any unwanted gases.
- AquaMedic CO2 Reactor M with Attached Powerhead : The CO2 Reactor M is a thoughtfully packaged solution for CO2 introduction into systems up to 125 gallons.
It integrates the CO2 Reactor 500 with a super-efficient 5 watt pump, which provides dedicated counter-current flow, neatly together on a convenient mounting plate. The Reactor M is supplied with suction cups to fix the system inside the aquarium, or space permitting, inside a filter sump.
- AquaMedic Double Membrane CO2 Reactor : The CO2 Membrane reactor contains a gas permeable membrane tube, impermeable to water. When connected to a CO2 unit, the gas diffuses through the membrane into the water - bubble free, with no losses. The Membrane reactor must be installed in the aquarium in an area of rapid water circulation.

CO2 Regulators
- Milwaukee CO2 Regulator w/Solenoid Diaphragm Valve & Bubble Counter : CO2 regulator by Milwaukee Instruments includes solenoid valve and bubble counter. Unit comes with dual gauges each with dual reading of both psi & kg/cm. Left gauge meters tank capacity and right gauge meters flow. Needle valve flow control provides for precise measurement.
- CO2 Regulator by AquaMedic : Pressure regulator for the precise control of CO2 dosage into the aquarium. This CO2 Regulator is chrome plated and offers: a fixed working pressure of 1.5 bar, a needle valve for fine adjustment.


pH Controllers
- SMS122 pH Controller by Milwaukee Instruments : Professional pH / CO2 controller especially designed for use in aquariums.
- SMS125 pH/ORP Controller by Milwaukee Instruments : With Milwaukee's Smart controllers you can monitor and control pH and/or ORP levels directly in your aquarium.
All our controllers work with a 12 VDC adapter and can be hanged above your aquarium.
- pH Controller by AquaMedic : AquaMedic's pH controller is a precision instrument to control the pH value in aquaria. In combination with a CO2 system and a solenoid valve, the pH can be maintained at a constant level, and the CO2 supply to aquatic plants or into a Calcium Reactor can be controlled.
The unit is supplied with a large LED display and the control range is digitally adjustable from pH 3.5 to 10.5.
The pH controller has a BNC connection for pH electrodes. The use of an original Aqua Medic plastic shafted electrode is recommended.
Optional AquaMedic Electrodes:
- AquaMedic pH Electrode AM78002 (low pressure)
- AquaMedic pH Electrode AM78006 (high pressure / screw type)

CO2 Solenoid & Needle Valves
- High Quality CO2 Needle Valve : Needle valves are used for the fine adjustment of flow of CO2 gas. High Quality CO2 Needle Valve.
- No-Shock CO2 Needle Valve : Needle valves are used for the fine adjustment of flow of CO2 gas. The No-Shock Needle Valves are excellent quality and have a large brass handle.
- CO2 Pulse Control M-Ventil Solenoid Valve by AquaMedic : TheM-Ventil Pulse solenoid valve features the latest in technology – pulse control. Energy is only consumed during the switching process and with a power consumption of only one watt; no heating effect can be felt on the valve body, even under continuous switching duty.
- CO2 Solenoid Valve by Aqua Medic : The Solenoid Valve has a high quality body manufactured from nickel plated brass with a maximum operating pressure of 6 bar, pressure fittings for 6mm flexible hose and can be connected to all our CO2 units.
- CO2 Solenoid Valve by Milwaukee : Milwaukee Brass Solenoid Valve comes with a 6 foot power cord. 1/8 inch FPT input and output.

- 5 lb. Aluminum CO2 Cylinder : 5 lb. Aluminum CO2 Cylinder, New. 19" tall with valve.
CO2 Cylinders are shipped empty.
Check your phone book under Fire Extinguishers, Fire and Safety Equipment or Welding Gas & Equipment for local companies where you will be able to refill the CO2 cylinder.

- 10 lb. Aluminum CO2 Cylinder : 10 lb. Aluminum CO2 Cylinder, New. 22" tall with valve. 6.9" in Diameter.
CO2 Cylinders are shipped empty.
Check your phone book under Fire Extinguishers, Fire and Safety Equipment or Welding Gas & Equipment for local companies where you will be able to refill the CO2 cylinder.

- 20 lbs. Aluminum CO2 Cylinder : 20 lb. Aluminum CO2 Cylinder, New. 28" tall with valve. 8" in Diameter.
CO2 Cylinders are shipped empty.
Check your phone book under Fire Extinguishers, Fire and Safety Equipment or Welding Gas & Equipment for local companies where you will be able to refill the CO2 cylinder.

Hexo-Manifold with 6 individual needle valves : This manifold allows you to dispense CO2 to six different tanks with just one CO2 bottle and one CO2 regulator.
It can be used in-line, or threaded (1/4" NPT) directly on to the CO2 regulator.
A precision needle valve is attached to each outlet for precise control.

- CO2 Brass Check Valve : These are the highest quality industrial-grade Brass Check Valve from German Air Pressure Systems.
Just like you, we also thought that these were unnecessarily overkill for aquaristic purposes, but it has been proven that these are the only qualified Check Valves for protecting your expensive CO2 equipment (Regulator & Cylinders) from saltwater with a pressurized Kalkreaktor pushing it backward vigorously.
Takes 4/6 mm (ID/OD) or 1/8" airline tubing.

- CO2 Check Valve by Azoo : Azoo Plastic check valve for water plant aquariums.
The check valve is usually placed between the CO2 regulator and the bubble to prevent water from back-flowing to the regulator.

CO2 Resistant Tubing : Regular air tubing can lose up to 25% of its CO2 before it even enters the tank. Silicon tubing loses up to 5%. This unique CO2 resistant tubing loses less than 1%.

CO2 Natural Plant System w/CO2 Activator & Stabilizer by Hagen : This system has been designed to supply any aquarium with a safe, economical and efficient method of providing aquarium plants with nature's most powerful carbon source for plants.
Employing a natural fermentation process for CO-2 eliminates the need for inconvenient pressurized cylinders. The system allows quick, easy and economical refills of ingredients to provide continuous CO-2 for a 3-4 week period. The special fermentation canister has been developed to support consistent carbon dioxide output.
Comes with: Fermentation canister, bubble counter/diffuser, CO-2 resistant airline tubing, 3 suction cups and a holder, 3 activator and 3 stabilizer packets (good for a 3 months supply).
Good for aquarium up to 20 gallons.
Size: 3" diameter x 7 3/4" high (8 1/4" with airline adapter)
How it works:
 Once the fermentation contents are sealed in the canister, fermenation takes place, which causes the creation and expulsion of CO-2.
The fermentation canister has a Thermo-Regulation system that buffers abrupt changes in temperature inside the canister caused by external temperature variations.
Additionally, the patented Pressure-Release safety cover prevents internal pressure from exceeding safe limits.
The CO-2 bubbles move from the fermentation canister to the bubble counter. There, the bubbles follow a 3 dimensional route.
This system has an extended diffusion path within a smaller area, providing longer contact time to ensure efficient diffusion (absorption) of CO-2 into the aquarium.

Continuous CO2 Test by AquaMedic : The Aqua Medic CO2 Long Term Indicator determinates the carbon dioxide content of the aquarium water in simple and inexpensive way.

- Bubble Counter Liquid : Special high viscosity liquid to prevent evaporation and spillage in Bubble Counter.
To be used externally only and comes in 50 mL spout cap for easy & direct application.
Imported from Germany.
