I tried searching and couldn’t find much quite similar to this.
2 year old stable mixed reef. About a month ago this green stuff started growing on my sand bed. It is pretty bright green, forms mats that vacuum up easily but do not break up very easily. Is only on the sand, nothing on the rocks at all.
Pictures below.
Im wracking my brain and can’t think of anything that has changed in the tank or my maintenance recently. I do a 10% water change every weekend. Vacuum what I can but it grows back within a couple of days.
Dose All For Reef and have for a long time. Parameters are currently (and have consistently been):
Alk: 9.5
Calc: 420
Mag: 1400
Phosphates: 0.03-0.06
Nitrates: 1-2
I pulled a chunk today and put it in a small bowl with straight hydrogen peroxide 3% and it did nothing to it.
Any idea what I’m dealing with here? Suggestions?
