I used starsan to sanitize my carboy. I didn't worry about the left over bubbles as everyone says. Well I aerated the wort for about 25 minutes with an aquarium pump and airstone prior to pitching the yeast, and these bubbles went crazy. Bubbles filled the carboy and snaked out of the top and over the side. I am pretty sure they are starsan related as they looked like it and were oddly stiff. I broke the snake off at the top and waited for it to subside a bit before pitching. The airlock finally started to bubble a bit 16 hours after pitching. The void above the wort is filled with these bubbles though. Should I be worried? Is this normal? I think I will rinse with pre boiled water next time. Hopefully when I rack to a secondary to dry hop, the bubbles stay behind.
