Strictly from test results using Hanna checkers, my NO2 is reading 0.17ppm and Phosphorus 10ppb=0.03ppm PO4, which I understand is very low.
From visual inspection though of the tank, I have green algae and other algae that I have not identified (GHA or Bryopsis?) in the pictures.
My understanding is nuisance algae will grow in the presence of excess PO4, so am I to ignore the Hanna test results and just take the visual inspection at face value and assume I have higher levels? And if so, start dosing bacteria, hydrogen peroxide and implement a plan to pull out PO4?
