Now that I think about it, I really wasn't paying attention to the temp when I had done the water change. But I did have a heater in the new water for about 2 hours or so while everything mixed. I guess that could have been my problem is not accounting for the temp. Or are glass hydrometer effected by temp.? I have a swing arm type hydrometer but I know for a fact that it is way off the mark, I just haven't taken the time to get it cal.
