After having my 220 for over four years, I just realized the temperature difference between the sump and the DT. I had my hand in a 78 degree tank, then put it into the 220 DT and WOW what a difference!
I put a probe in the DT, and sure enough, only 74-75 degress. So I bumped the temperature regulator up to 81 yesterday, and the DT is hovering around 76. I'll monitor it for a day or two and maybe increase the sump temperature a degree a week and see what happens.
