guys, i need some help, i just ordered a mcp655-b 2 weeks ago, it finally arrived and connected it in serial to my current loop...put it before the current mcp655 thinking it will create more flow ... to my surprise my temps are still the same infact worse ... please help any1 ... i just spent a lot to money on the new shiny 655-b
However, since your temps did not improve, that tells us that head was never an issue (which is not surprising, the 655 has enough head for practically anything. You could try running the pumps in parallel for ****s & giggles. insert a y-fitting after your res, connect your two pumps, and use another y-fitting to merge them back together.
