I pitched a 96 ounce generated glob of active yeast starter into a 1.072 OG wort under 24 hours ago. The yeast is going nuts already. I'm not used to such crazy yeast activity this soon... I also normally go with ease of use and pitch two packs of dry yeast seeing fermentation begin (slowly) about 24 hours later. I'm worried I might have an infection, but not using big yeast starters, I'm not sure if I should be concerned. Thoughts?
