Hey all! I have an 8 month old RS Reefer Nano with this brownish encrusting algae on the life rock. It started out as small speckles and has grown to a larger mass as pictured below. I am unable to blow it off the rock, but can chip it away with my finger. The speckles are slowly getting larger on the rock that is exposed to light. Nitrates <10, phos .02. Any thoughts on this would be appreciated! Pics below under white/yellow lighting.
Thanks!
Thanks!
