Use a piece of airline tubing to siphon things out. Even an unused turkey baster will work for removing stuff. What I do on my system for weekly water changes is mix up 5 gallons of water the day before. When I go to do my water change I hook the new water into my ATO. I then siphon out my water and do any necessary cleaning/removal of whatever is needed. By removing things prior to/during the weekly water change, whatever is sturred up into the water column is also removed from this water change, like algae spores and poop.
