I have this blackish algae that is on the rock- can't scrape off. It seems to have taken over my candy cane coral and is now on my montipora too.
I realized two weeks ago my phosphates had been high and I think this is where the problem started. I added GFO and a filter mat in the filtration and within a week phosphates dropped from 0.9 to 0.07. However, I don't know how to get this coral back to healthy, if I can.
Second issue, my duncan was thriving until the phosphates dropped. Now it looks terrible.
I do tend to get greenish/black algae in the sand bed pretty quickly. I do stir it up and try to vacuum the sand during water changes where I can without damaging the other things in the tank that are around.
All water parameters are within a good range. Just now sure off what to do next.
Salinity 34.8
Temp 79.8
Nitrate 5.0 ppm
Nitrite 27 ppb (0.027ppm)
Alk 9.7
Phosphate 0.07
Calcium 478 ppm
Here are photos of the candy cane before and after, the montipora, the rock close up, and the duncan before and after.
