You answered everything yourself. And who did you feed? If it was only the corals, then don't feed them at all now, and do a water change. Look for someone in your city who has an osmosis system and fill it from there. There might be a problem with distilled water; if the coil in the apparatus is made of copper, it could backfire.

Thank you, I bought the distillate at the car market, in a sealed bottle. I have 1 dogfish and 4-6 shrimp as pets... I probably overfeed them, but I do it once a day; now I will give them less, but more often. I discovered another problem: my skimmer was not working properly for a month; I installed it much higher than the water level. It was working, but not actively. Now I've fixed everything, and it's skimming the water like crazy. Overfeeding and the skimmer seem to have played their role... I hope the algae will die off and fall off the rocks, or is it better to use a brush? How can I get rid of it now? P.S. It's strange, but all the corals are alive and look healthy.

Can someone else give a hint? How to fight it?
