How to get rid of algae. Is killing my corals

lets start with parameters first. there will be a bunch of people that are going to be asking about those, so may as well post lighting schedule, nitrate, phosphate, how old the tank is, at the very least.

Also what kind of lighting, what are the PAR readings of the coral and how old is the tank?

just as a spoiler alert, i dont think its the algae that youre having an issue with, when it comes to your corals, but the culprit behind it is likely the cause of coral issues and your algae

I started using macroalgae after my tank cycled which was 1.5 mos ago to outcompete microalgae and the only algae issues are diatoms but that only lasted about 5 days. I have a 6 gal, something to consider just be careful macroalgae can bottom out your nutrients but a quick over feeding and good CUC can fix that, but I’m a newb with lots of fw experience I’m sure one of these expert reefers can chime in on this.

What do you think it is ?

Agree with this. Algae can kill corals. Nothing I see in your pictures is showing algae that would be harming the corals though.

algae in itself, if it is killing corals, your issue will be significantly worse than what it is. i would suspect phosphates or nitrates being something that is causing it. thats just my guess, but thats where i would start specifically, which is why i suggested to mention all of your parameters.

Kh is 230.5

Your kh, what measurement is that in? My dKh is 10

It's really high but i read that I goes down by itself.
I tried to lower it down with white vinegar like someone said and it killed a few corals.
Not hearing that mf again

is your 230 reading PPM? or is it in DKH? it would HAVE to be PPM. there i no time in the world where 230 dkh would be read on a aquarium tester, nor would it drop on its own that much. the conversion would be in the ballpark of 12-13 if that number is in ppm.
assuming that is the case, i dont see any real reason why your water parameters are causing anything IMO. maybe the KH, but thats making assumptions and wild guesses. i still feel that its something else tho, unless there is an unknown contaminant in the water.
how long have they been closed?
