When I had a tank and was running cheato (great stuff, I might add!) I did my culling and leaning of cheato when I did my water changes. I kept the old water in a bucket, and simply vigorously shook out the cheato in this before I dumped the old water. That way you don't re-release all that poop in the tank.
Best of luck and have fun!
