Excellent! That makes a person sleep easier doesn't it?
I run my air at night and typically check my temps in the evening. My latest temps from top, 18' down, and to bottom were 87, 84, 77 F.
I don't think I actually have a thermocline by the strictest of definitions. I believe my delta T is from the water flow stopping during the day and the upper portion starting to heat back up.
I think I will try and measure temps this evening at 1 foot intervals to investigate. I thermocline should show up as a significant change in temp from one foot to the next, otherwise, I am betting my temps just gradually get warmer the closer to the surface.
