I got the same loop.. It is 2 years since I use pastel red with the same components.
never had flow issues.
Using distilled water I had flow about 220 L/h. So nothing wrong with connection, waterblock or radiators!
The only difference is the liquid used.
I have not cleaned the loop (obviously I cleaned the radiators with vinegar before using them the first time), if you mean using bicarbonate to normalize pH, after using distilled water. I will do (con you repeat me the procedure? I dont find it on the first page) but i dont think it is related to flow issues.

I use two flow meter, one mechanic aquacomputer highflow and one aquamputer mps 200.
Never had issues before, I repeat I have been using pastel red for about 2 years. And I used distilled water just for few months.Edited by liberato87 - 4/28/14 at 5:59am
