Ph
 

I am just wondering if anyone does anything to control pH in their tank? Is anything ever needed to be done to buffer it? maybe someone could lead me to a link to explain some of this, thanks

The chemistry in a reef is rather complicated. I'd like to point you to just one article on the whole mess, but there really isn't one.

Here's a whack of articles that will give you both a headache and some great information on reef chemisty. Read them often :)
