I've looked on the forums here but haven't seen this addressed. My beer has been in primary for a few days bubbling away happily. Looking at it, I can see particles in the beer rising up, down, and all around in a convection current. The fermentor is room temperature at 65 degrees with a towel wrapped around it as an insulator.
Is this convection current normal? I'm merely curious, not concerned.
