The good news: you got algae!Is this green coralline algae? It won’t scrub off with a tooth brush. It is not on the sand at all; what you see on the sand is cyano/a totally separate color under blue lights. I introduced some pink coralline to my tank about three weeks ago through a hermit shell. The green has really ramped up lately over the entire main rock within the last two weeks. *Pictures are taken under very bright whites!!!!* But like I said, it won’t scrub off the rocks. The rocks were wet man made live rock. I do not believe it’s hair algae because it seems to be very flat and hasn’t grown hairs over the last few weeks.
Tank life: ~8 weeks
Parameters:
Alkalinity: 9 dKh
Calcium: 450
Nitrate: 7-10
Phosphate: .25
Magnesium: unknown
Salinity: 1.024-1.025
Temp: 77-79
Ammonia: 0
Nitrite: 0
I have some Cyanobacteria that has grown on the rocks after I beat the Dino’s back about a week and a half ago after I increased my nutrients through feedings, put in a UV, and did a lights off period. I scrub the cyano daily and it remains at bay, but it comes off very easily. It won’t grow over the green algae at all. In fact, the green algae seems to deter it. The green also encrusts the rocks and appears flat (no bubbles or hair).
I have two cleaner shrimp, two hermits (blue leg and red tipped), three snails, 4 nassarius snails, two clowns, a yellow tail damsel, two sexy shrimp, and a YWM.
I also have just added pulsing Xenia and GSP. But I had added two FL ricordea frags, two Duncans, and a candy cane a few weeks ago. All are doing amazing, and have grown almost immediately upon putting them in the tank.
The bad news: it ain’t coralline :/
