I did not know res temp until recently, when I started getting temp it was around 85, without icepacks it is 74, I introduced some ice packs in the res today and will try and retain a temp of 68. I'm in the middle of my grow so it was hard to attempt to permentaly light proof it right now, but I jerry rigged black plastic bags around the res, and added a cardboard cut out for the top of the res, it's nice and dark now. After this grow, or death, I will permenatly light proof the res with black duct tape.

I had a little orange on one of the roots about a week ago and believed it to be nute stain, however, now that all of them have it, and the plants look sick and wilted, I think it's rot. I have pictures in my album if you'd like a look.
