Well after much more prep and vial cleaning and careful testing, I think I have 0.00 phosphate, which is good I suppose.
I mainly got all in a panic since I added some base rock (15 lbs) about 6 weeks ago and some large dry rock (20 lbs) shelves about 2 months ago (the shelves at least cycled in a rubbermaid for a while) -- but on last test ~ 3 weeks ago it was around 0.08-ish, so dropping to 0 is odd, but 2 hanna tests, and 2 elos tests show nadda
...so I suppose I can trust the SPS:
