Ok back to the cab with what I thought was having some problems with. After 10 days in the carboy and not seeing any activity and the sg. staying exactly the same I starting to wonder if something is wrong. Do I wait longer and check again or does it sound like the yeast has done nothing for the past 10 days and I need to get this going again? At this point I according to the directions I should be getting ready to clear. The only other thing I can throw out there to why nothing has happened as the temperature is about 5 degrees F lower. So I'm just curious if I leave it alone for another couple days, add yeast, or add a heat belt?
