Didn't mean there were negative values.... most items I realize are Parts Per (depends). Ph, is a logarithmic scale, SG is a relative density compared to pure water... got all that....
I think the 'stabilized "good" readings' is what I am trying to drive to more details. I measure ammonia, nitrites, nitrates, salinity and Ph, but my LFS did tests for alkalinity, calcium, and phosphates over the weekend.
I am working on the alkalinity and calcium with the help of my LFS... I'm just trying to learn the lingo a bit, and make sure once I start slowly populating my tank, I take into consideration my skill level (low) and the 'health' of my tank.
