does this mean mag drive is has less noise compared to external pumps like iwaki and little giant? i'm interested to know since my tank is almost done and my wet/dry and stand is waiting inside my garage. have a CPR CR-3000 440 gal capacity for my 180 gal tank.
would it be better to be internally or externally on mag drives? they said it would produce heat on the water but wouldn't that be good since your heater wouldn't need to put too much heat anymore? or does it make the water really warm to a point of 79 and up? i just need my tank to be at 77F. planning to have 2x 250W stealth marineland heaters on the 180 gal.
