I'm in the process of setting up my Auto Water change station. I have to move water about 15 meters from my mixing station to my tank. Then I have to move the water from my tank to a nearby drain (15 meters).
I'm looking at setting up the Maxi near the tank.

1. Can the Maxi pull water from 15 meters to my tank? How best to control air in the line?

In a perfect world I suppose I would have two Maxi pumps. One in each location pushing water. But that's not very cost effective. Perhaps GHL can come out with a Single head Maxi?
