Are you suggesting just pumping air into a diffuser (glass or ceramic) instead of an airstone in order to increase CO2
in your tank, without any method to generate CO2
other than what is already in the atmosphere? If thats what you are saying, you aren't going to get any results different than just using an air pump connected to an airstone, as far as CO2
concentration is concerned.
concentration is approximately 0.0314%. By contrast, CO2
from a DIY setup is anywhere from 78-98% pure CO2
, and compressed CO2
in a high-tech setup is 99.99% CO2
