Ph always low.

I have a small fan clipped to the top of my tank that I use for cooling. It's also useful for raising the Ph a little bit as well.

Here is a great article about pH in a reef tank. It really helped me understand it. I was having a low pH issue and that with a post I made on here helped me solve it without doing any pH buffers. I also discovered that my low alkalinity was a huge factor in it as well. Since I opened up my fishroom where the sump is to outside air and stabilized my alk, my pH has stayed at 8.2.
