I was just up looking at my tank, and there appeared to be a clear Bubble sitting on the sand near a LR. It was clear a lil smaller than a dime, I knudged it when i was removing something next to it and it didnt pop. Has slight white/tan lines, or dust looking on it. Anyone KNow????

No, I cant find the cord that connects my camera to the computer.
It is still there this morning, just looks like a big spit bubble lol, with sediment laying on top of it.

Google bubble algae and see if that fits?
