My semi-new (2 month old) pavona cactus doesn't look good! Is this algae growing on it? It's low in tank (but high light) and has direct flow with random wave Red Sea Reef Wave 45.
Should I scrub algae off with tooth brush and move higher? Maybe stronger flow?
Tank parameters below.
Salinity 1.025
Temp 76.9
ph 8.15
Alk 8.3
Ammonia 0
Nitrite 0
Nitrate 2.5
Phosphate 0
Calcium 465
Mag 1360
