People always talk about how BTA's require "stability" since stability is more of a concept than a recipe, I wanted to discuss what people feel "stability" means for a BTA as well as the general ranges people have their tanks at.
Let's talk both ideal "target" values as well as the typical range of measurements you see week to week and month to month
-Nitrates/phosphates (Barely detectable/0-5 ppm nitrates, etc.)
-Alkalinity, Calcium, Magnesium (for instance, dkH stays stable between 7.5-8.5)
-Temp (i.e. 78 +/- .5 degree, etc)
-Salinity (i.e. "on a handheld refractometer calibrated with 35 ppt calibration solution, I cannot identify any salinity changes/I run an auto-top off)
-PAR range
-Other factors to consider in "stability?"
