The cycle has been complete for a little while. I added the CUC a couple weeks ago. I now have a YMG, yay. I also picked up a chiller so my heat issues are solved. The fan simply was not enough to evap cool the water. I needed something like 8+ degree drop. Was running about 80 with no lights on. The Apex does a good job of regulating the chiller. If you have the means, get a controller, highly recommended.
