There's another thread on this toping going as we speak. But I use Reef Buffer by Seachem.

Dont add anything yet. We need to make sure that there arent any obvious problems causing it first. It would be bad to dose something otherwise.

Do you have a tight lid on the tank? If so, its not allowing for gas exchange, which lowers pH.
Do you have good surface agitation? If not...same thing...

Take a glass of tank water and put it outside with a bubbler/airstone in it...test it again after an hour or so and if its higher, then you have an indoor co2 problem and need to open windows occasionally

Siredudeguy is right. High CO2 will depress pH. If you're a new reefer...get good calcium and alkalinity test kits (I use Salifert) and you will never regret it. Chances are good that your alk is low. Calc and Alk work in conjunction though so look up Randy Holmes Farley articles on the subject - this will save you thousands and make the hobby much more enjoyable in the coming years.

If you have OK calcium and your alk is low you could simply use baking soda. It works fine - no need for expensive specialty products that are essentially the same thing. Go to jdieck's online calculator and you can figure out how much you need to add. Bookmark his site because you'll be going back...

Buffers are seldom useful in maintaining pH in reef tanks. If you don't want corals or coralline algae in the tank, the Marine Buffer product will help, though. This article covers low pH problems:

Low pH problems almost always come down to high CO2 or measurement problems. How low is the pH in the tank, and how is pH being measured?
