Noticed a big bubble forming in one of my caulastrea heads. While I was watching, the polyp quickly deflated shooting out a bug white cloud. The buble is still there. Is it spawning? Is this an egg sack?

Update...
Turned out to be an air bubble. While I was well aware that too much light can cause excess oxygen production, I have never witnessed such a pronounced example. Here's some pics...
