Controlling temp

[JDigital]

I would say a RKL. I've got one for my setup and it keeps my temps between 25.2-25.3. Like mentioned if in the summer you need to run fans to help cool the tank you can program them to come one a whatever temp you like.

I'm hoping with LEDs that I won't need to add a fan to my system. The consistency of my temps on my Home tank compared to my office tank are drastically different.
