reef buffer

Hello guys I’m here since I KNOW I shocked my corals I just want to figure out which thing I specifically did to shock my corals or if it was a mixture of it. So the basic run down, I tested my tank and saw that my PH was incredibly low, (7.5) my magnesium was low as well (1080) my phosphates...

I used Reef Buffer to raise my ph, I knew it would make the aquarium cloudy and it made the glass white (used last night). My question is what is the best way to clean the glass with the white particles on the glass. You can see where I used an Algae scraper but it’s barely working.
