You can buy SW buffers. Be careful adding these. It is best to figure out why the PH is low. The salt mix has PH buffer in it already. If the PH is low then something else may be wrong within the tank. The PH of a healthy system is always on target.

what does everyone use to raise their ph?
I never ever add anything to raise the PH of my system. I look for the problem causing the low PH and fix the real problem.
