Tank is about 8 months old and was carefully cycled and waited long time before turning on lights, coraline starting to cover good amounts of rock. No fish in tank currently just corals and snail, crab, shrimp.
Ph 8.3
Alk 9.1
Nitrates 3.5
Phos 0.03
Calcium 476
Mag >1500 with salifert kit
SG 1.026
Temp 78 always
Never had any issues with algea until now , have a 16 gallon sump with cheato and red ogo , seeded well with pods and can see them easily on glass.
This algea is dark color and stringy, my turbo snails do eat it readily or else it would have taken over by now. Not sure what type this is, doesn't look like the ones I was prepared for. I do 15% water changes weekly with home made ro/di water.
Any help would be greatly appreciated as it seems to be gaining ground despite good tank habits.
