I was trying to get my PH up, as it was only 7.7. So i bought some PH buffer at my LFS and thought i read the instructions. But because my eyes arent what they use to be, and the print on the bottle was so small, i didnt see where it said to mix the powder with water and i just put it right in my tank. Now ask my corals are closed up and stunt open. What do i do Now?
