Interesting thread.... and I want to get input that I think others may find useful, as I would.

When y'all talk about stability, please define that as ranges per day.

Ca - +/- x ppm
Alk - +/- x dKH or ppm
Mg - +/- x ppm


Let me tell you why this is important for me... when I hear stable, that means steady consistent levels. Calcium runs 420 all the time for example. Or Alk is 9.5 all the time....

However, in our tanks, that constant value is almost impossible. Daily dosing say 70ml of Alk solution (two part) is to offset the .3 or .4 drop in dKH (15-20 ppm) per day. If you do that all at once, its not 'supposed' to be hard on critters. .5 is generally the acceptable daily change amount. However, by having to dose to adjust that level back up to your 'ideal' value, its by definition not stable.

See what I am getting at?? So please define stable and put some values attached to it.
