Everything is quite good. But why in the nightstand? And what's on the nightstand? There are people on the forum who are actively engaged with the Black Sea. I'll try to find them.

Thank you for the links. Why in the nightstand? Because it's like a temporary holding, a training exercise with cats, well, there was space there (just kidding). Once I practice a bit, I'll set up a mini reef on the table, tropical, salinity is currently tropical 1.025. In the nightstand, it's still fresh water, plants, angelfish. The personal reserve of the commander-in-chief. Once I sort out a couple of problems, well, I'm already cautious, careful—it's the nature of the profession. The skimmer is gradually pulling out dirt, a film is forming on top, the crayfish are sticking, the anemones are barely opening, and the algae are growing in ways I don't want—need to figure out why.

By the way, I do not recommend keeping cystozira in a tropical marine aquarium. It will perish, turning the water brown. Besides ulva and phyllophora, other Black Sea algae do not survive long in a tropical aquarium. It's due to the salinity, and apparently, the light needs to be suitable as well. However, fish and crayfish have no problems.

You answered your question correctly. Your aquarium has already taken in the amount of biology that was necessary, and the dying algae are not good; they need to be removed, leaving, as I mentioned, ulva and phyllophora. Since the aquarium is on its way to becoming a tropical reef aquarium, the algae you mentioned from the temperate Black Sea are no longer appropriate here, especially since its salinity is almost half lower. They will only worsen the GH levels in your aquarium and harm the biology that is already functioning.
