Ya, what's weird is with the 1st generation controller I got with the pump, I was probably pushing over 1000 gph. According to the factory charts I should be able to push over 1300 gph at 12' of head, so I figured it was probably close.
A friend had their's running far earlier than mine, but it fried the controller because of poor cooling design. RLSS sent us all new controllers even though I hadn't even run mine yet. My friend ultimately shut their tank down and got out of having a tank because of the damage everything caused - but that's a whole other story....
So I finally have mine up and running and since I still had old controllers, I decided to run them side by side with the new controller to see the difference when I filled up my 210. I'm running 2 separate returns that run side by side so the comparison should be spot on. Well the new controller I bet doesn't put any more than a few hundred gph. It totally sucks compared to the old controller.
I would TOTALLY be open to running it wide open with no control. With the head pressure I'm running at I need all I can get. I just need to figure out how to make that happen without burning up the pump
