Aeration and its effect on pH

[KurtV]

I think your TA is fine, especially with very low levels of calcium (what is the calcium level, by the way?).

Thanks Marie and Kurt for the helpful advice and words of support.

Kurt ....... I really can't tell what my calcium level is. All I know is that it is so low that my Taylor drop tester can't determine the level. When I set up the test, the color starts off as a purpleish blue (not red as the instructions indicate) and does not change.
