You know I have one Chase. I personally would just go with 2 tunze and a controller for the money I have in my CL if I had it to do over. They are neat but by the time you buy the unit, a pump, holes drilled for the CL, and the plumbing nightmare, not to mention the small fortune I had in ball valves and union joints! Just depends on if you want 2 big power heads in the tank is all I guess. The main thing I don't like about mine is the way I did my plumbing. Like I said the unit is pricy but pretty cool how it works.
I agree Paul from OM, the owner I guess, is super helpfull. I emailed him a question and instead of a email back he actually called me on the phone. I talked to him 3 times on the phone and he was very informative and nice.
