What is this and how do i get rid of it?
All of the old growth on all of my large leaf plants have this algae. In 125G discus tank, nitrates at 5-10, ammo/rites 0. Co2 @ 2 bubbles per second adding flourish regular, brightwell iron and potassium each 2x a week.
I have 3x SAE's, 10 or so Ottocinclus, 4x decent size Bushynose, what is it and what do i need to do to get rid of it?
