A bubble counter determines how much gas is going through the airline. It is counted in terms of bubbles per minute (or other period of time). The bubble counter is located between the CO2 regulator and reactor in a CO2 System.
For the Hydor CO2 Green NRG Advanced use the Hydor NRG CO2 Disposable Cartridge. For CO2 systems using the American standard threaded regulator use the Red Sea Cylinder Bottle.
We carry the AquaticLife CO2 Regulator w/ Integrated Solenoid Valve and the Milwaukee Instruments MA957 CO2 Regulator w/ an integrated Solenoid Valve and Bubble Counter.
A solenoid valve turns on and off the supply of gas to a CO2 reactor or calcium reactor. When using a pH controller in conjunction with a CO2 reactor, changes in pH will turn the solenoid valve either on or off according to settings.
An aquarium CO2 system is necessary for calcium reactors and for dispensing CO2 into freshwater planted aquariums. Healthy and luxuriant freshwater aquarium plants require the presence of adequate carbon dioxide. The movement of pumped water causes the elimination of carbon dioxide through the water surface. Plants without carbon dioxide turn yellow and lose strength. CO2 systems are the best way to effectively add the required amount of CO2 to a freshwater planted tank.
To have a complete aquarium CO2 system you must have the following:
