airstones are bad in saltwater. maybe just stick the tubing in your tank for large bubbles. also increase your circulation ; aim your pumps toward the surface.

Assuming your problem is too much CO2, that is...

Excess CO2 is the most common problem from overstocking, overfeeding, insufficient circulation, or a skimmer that isn't functioning at 100%.
However; metabolic acids from the breakdown of organic material is up there as well, followed by low Alkalinity.
