Yes, IMHO the MCP655 is a very good match for the Storm...
The following table is from the
Swiftech MCP655 12 VDC Pump review at SC.c
For this test I am using an open, constant level reservoir > Pump > 6x6x2 heatercore > Storm WB > 5 gal graduated bottle (4' of 1/2" ID silicone tubing).
The small MCP350 (DDC) beats out the much larger E-1250 due to higher head pressure. I did not test the CSP-MAG but I would expect it to fall below the E-1250.
