PH drops when the ammonia increases.

It will become more stable once the tank has enough bacteria to convert the ammonia (how old is the tank) and as the alkalinity is increased.

Do you use a Buffer?

Check your alk. I had problems with low pH and attributed it to poor oxygen exchange. I removed my glass top and that helped. Use a PH to give some turbulance at the surface to aid in gas exchange as well.

Would a bubble wall help? or would that be bad for the tank?

It is not bad for the tank but it would not be as effective as a ph to ripple the surface. Good water flow is needed in the tank anyway so it will be doing double duty to help. Most people in SW stay away from bubble walls but I have never been told any reason why.

It does not really look natural, and causes major salt creep.

when did you test your ph? ph will change from when the lights go on until they have been on through out the day due to photosyntasis (sp?)
