Can anyone identify what this new brown substance is growing between the heads of this blasto? Recently started feeding heavier to increase nutrients for my SPS which were losing color. I've been seeing more algae and Dino growth, but this is new.
200 gallon mixed reef
Live rock is 2 years old, but this tank is 1 year old.
T: 78F
SG: 1.025
Ca: 430
Alk: 8.6
Mg: 1400
Nitrates: was 4 last check but haven't measured in the last 3 weeks and I'm sure higher now
Phos: needs an update
