Hello. I will be setting up my w/c setup (not my first w/c attempt) which will be a D-Tek TC-4 waterblock with 2 chevette heater cores( running in parallel), and with an Eheim 1250 pump. All this will be cooling a pelt, so my question is: with the Eheim 1250 will I be able to get a decent flow rate (1.5+ gpm) through the heater cores (will be after waterblock) or will I need something like the Eheim 1060? Oh yeah... this will be a 1/2" system.
Thanks
