Dear users,
Suddenly out of nowhere my aquarium is covered with brown stuff. Snails died, and corals - especially polyps such as greenstar (which has been very thriving before), and zoa are retracted and seems to be very stressed as it is all covered by that brown stuff. It can be dusted off in some areas, so I thought about diatoms, but it may be sticky in others + snails die-off = maybe dino. Phosphates are not detected, nitrates around 3 . I have collected some of the stuff from the covered corals and put in under the microscope. I attached the images, but please check the video, as *it* moves and maybe this is more informative.
Do I understand correctly that it is some kind of diatom after all, not the dino?
Thank you very much,
