Get yourself a PH buffer additive.

Do a water change first that will probably do the trick You dont have a glass top do you?

 

[mattt6511]

yes i do have a glass top

Do you have a sump? Or just the main tank? If you took some water out and let it sit for 10m or so does the pH test higher? A common problem with closed top tanks is that the CO2 gets trapped under the glass and supresses the pH.

I was going to say what phyl said that that probably is one of the reasons for low PH. You might want to remove and put eggcrate over it or like mine nothing at all.

should i have a air pump of some sort in my tank to put oxygen in the water>??

SW systems get their oxygen from a gas exchange process that occurs at the surface of the water.

Removing the glass tops on your tank and pointing a powerhead towards the surface of the water will greatly improve the gas exchange process and bring your pH back in line. Air bubblers don't really do much in a SW system other than create a big crusty mess of salt to clean up from all the bubbles popping at the surface.
