What kind of controllers do you like?

[sillygoose]

I need to moderate temperature fluctuations and would also like to change up flow with my power heads going on and off occasionally. What do you use and why?

If that's all your looking to do, I think an RKL would be fine. I've heard a lot better reviews about the Apex units but it just depends what your trying to do. IMO, for the basic stuff you can't beat $100.

Yup, Reef Keeper is great I have the original first one, still working perfectly( I don't remember how many years, 10?) Even this one had several flow options, including Night flow. I think the new ones are internet updateable, and computer programable
