So to follow up on this. I've also read that too much iron can cause this algae. I've lowered the time that the lights are on and lowered how much Fe I dose and it is seemingly gotten worse. What have you tried to control it?It looks like iron and light are the drivers for this algae. I unfortunately have lots of experience with this. It doesn't go away for me, maybe it's my tap water or the dirt I'm using. Best I can do is control it.
I've been struggling with this algage for almost 2 months. My CO2 is pretty stable and I've made the changes I described above.
