So I thought I'd share some info on my pump choice.
It's a DC pump similar to a Tunze and comes with a controller. The controller has three adjustments but is quite limited. Basically three nobs control the time limit the pump is run at "small" power, "medium" power and "high" power. The pump works very well and runs absolutely silent and doesn't seem to generate any significant heat. The only problem is that on the high setting it will destroy my tank so I had to modify the controller so the high setting does not turn on, normally you can only adjust it so it turns on for 2 seconds (you can't actually turn it off). The pump does generate a lot of flow and for the price it's a good deal. The only down side is the size as it's quite large. I had to cut shroud basically right down to the impeller to make it fit.
I plan on making a new controller for the pump similar to that of a tunze single controller, I want two adjustable power settings with a adjustable pulsing time.
