Could be the beginning stages of cyano. I see the "symbiotic bubbles" before I see the cyano sometimes.

+1 with Tizzo, could be gases from trapped nutrients.

How long has sand bed been in? Could just be sand bed doing it's job. When nitrates are broken down that's what happens. And yes bubbles on surface of sand sometimes occur just prior to but usually during a cyano outbreak.
