• Green algae has sprouted.

This is the alga Halimeda, which usually grows in "stabilized" aquariums and at high calcium levels. It is also called the limestone cactus. When water parameters fluctuate, it turns white.

What an exact answer!!! Yes, I decided to experiment a bit and started adding some calcium chloride and magnesium sulfate to the aquarium. At night, it turns white, but in the morning, when the light turns on, it quickly takes on a green-yellow color of the leaves. Now I will try to look for a detailed description of this Halimeda. Thank you! I googled it. Unfortunately, there is little information and it's very general. I would like to know more...

I do not recommend cultivating it. The fact that it grows is a good sign, but as it spreads, it quickly takes a lot of calcium from the water. It will compete with corals. You can keep a small bush.

I also have something like that growing on a small stone, but it doesn't grow any further... It actually looks quite nice.

It attaches very strongly to the rocks and is difficult to remove from them. I have seen mature reefs where there is a strong battle with Halimeda, and it is necessary to thin out its growths 2-3 times a week. It is better to keep it under control.

It was surprising that there had been no news of her for a whole year, and now - hello. Is someone eating her?

I haven't noticed any of the surgeons paying attention to her.

Surgeons do not eat, tough.
