Hello RS,
Two weeks ago I decided to upgrade my tank with new lights (replaced one fluorescent of my RSM 130), new pumps (eheim 600), skimmer (Tunze 9001)and added carbon (Fluval activated carbon) .
Since then, I observed strange behaviour of my RBTA and many corals.
The anemone hide for few days and came back to its spot but is not as expanded as before.
The torch coral won't open and this morning I observed it may be dying (bleaching? ). Also, There's a strange organism growing on its side. (see pictures).
My biggest blue mushroom is shrinked and dark.
All fish, candy cane and Xenia seems to be doing OK.
Besides all that, there is a major brown hairy and cyano algae outbreak. I've been doing water change (RO/DI) every other day but I couldn't see any beneficial effects.
PH 7.4
Salinity 1.025 (stable)
Nitrites 0.2 ppm
Nitrate 2 ppm
Temperature 78°f
(Unfortunately I don't have alkanity, calcium or Ammonia test kit)
What could be causing this major problem and what can I do?
