the best way to get snake poop out of water?

well, self explanatory. thor pooped in his water. im wondering what kinds of ideas people can come up with to get the poop out of the water without changing the whole bucket of water. i tried using a Styrofoam cup with holes poked in the bottom as a kind of net. it kind of worked, but the poop did break apart some, so ill have to do a water change. any ideas?
