I always suck it from the sumps on all my setups, I also pump it back into the sumps. I ran pex pipe from all tanks to my laundry tub and just bought a pump to sit in the sump. I also have some pumps in my mixing station/tank where it is also pumped through pex piping back to the sump.
Never lift a finger, take a look at my 375 gallon build for pics.
Thanks
Corey
