Need some help

[reeffreak9]

I have little bubble all over my tank. I have them on the sand, rocks, corals and even the snails. What is causing this and what can I do about it?

I had this once MANY years ago (about 15 years ago). I did a LARGE water change (almost 1/3) and added carbon and it went away. But I did stir up the substrate with my water change (maybe it has something to do with a buildup in the substrate?). I cant tell you what it was, or what caused it. I just know thats how I fixed it. My fish had popeye too at that time, and that went away as well (less than a week). Hope someone else gives you better advice.
