I have searched the net on what O2 level are good or bad and seem to find a lot of conflicting information . Is there a good chart or something that gives the O2 levels at different temps and gives a minimum and acceptable limits for different breeds of fish ? I know O2 saturation at maximum would be ideal but in the real world what are the real numbers ?
So far this is about the closest thing I have found .
Any input ?
