Question for Calcium Reactor user

[samksy]

Just curious what kind of co2 grade you guys uses. Lab? food? or industry grade co2? I read that industry grade is not the best to use but was wondering if any one is using industry grade and had any ill effect.

Never knew there were grades to CO2 until I looked, but found this on a few planted tank sites...

In the United States there are two basic grades of CO2 that you can find. Beverage/food/welding grade which is 99.99% pure CO2 with the main contaminant being water. The other grade is Medical grade. Medical grade CO2 is 99.999% pure. That extra 9 costs a lot of money. Some places will try and tell you that there is a difference between welding grade and food/beverage grade. If this is the case then that difference happens at their location. If you could be there when the CO2 truck comes you would find that they fill both containers from the same truck.
