Finally going to go with bottled co2 for my 36gallon, can anyone recommend some good places to get the tank, regulator and good diffusor/reactor. Thanks
ok. well rex grigg offers great personal service. he makes sure you get what you need. the others is more like buy what you think is best.
Solenoid isnt a must but its nice if you want to turn your co2 off at night or want a ph monitor.
bubble counter isnt a must but is nice.
