Chaeto color

[haleyf1024]

Hello all, I remember reading a tear or two back about the color of chaeto. I seem to remember that super dark green with slow growth meant something, such as iron deficiency or too many nitrates or something. Does anyone know about this? All I can seem to find now is “too much/little light”

Is it possible that you are not getting any new growth because of low phosphates and low nitrates?

What are your phosphate and nitrate levels at? And just for curiosity what light source are you using?
