Can't wait till this becomes available at a US Retailer, Question.

I am considering buying a (PMP-450S) to run in serial with my existing Swiftech MCP655-B. I am toying with the idea of having the 450S as the pump pushing water OUT of the res while the 655B sucks water into the res.

With reference to the picture Tim posted with the serial loop adapter, the 450S would be P2 and the 655B will be P1.

Question... will mixing the pumps be an issue?

I suppose I'll need to buy a Koolance (CTR-SPD24) 24V Pump Controller to maximize the output of the 450S?
