Fresh Air

Yay, sometimes I think the more I monitor my water quality the more paranoid I get about little changes. That being said you can never be too careful and its always better to test more often than not at all.

one way to check to see if it is CO2 buildup is to take some water from the tank and test the pH. then, put an air stone in the sample and let it bubble for a while (15-30 min) and test the pH again afterward. if the pH goes up, you are getting a buildup of CO2 in your tank. it may be caused by the need for fresh air in the space around the tank or it may be caused by a need for better gas exchange for the tank. i used to keep an air stone in my sump to keep DOC DO (dissolved oxygen) levels up and encourage better gas exchange for this exact reason.

Not to be pickey, but DOC is Dissolved Organic Carbon, and this is what you dont want to to have at high levels (ie nutrients). I think what you meant to say was DO or Dissolved Oxygen. Just wanted to clarify.

yes, thanks for catching that.
