Had trouble with counterflow chiller (first use). I was putting too much pressure into it from the pump, and it was forcing beer out the O2 stone because I was trying to slow the flow using the ball valve on the bottom of the fermenter. I allowed more flow, but that increased the temp to 90'. So I had to pitch the yeast at around 90'.
Next time I have to put a ball valve on the output of the pump, then flow through the counterflow chiller and O2 stone.
