Conclusion: We cut a bottle in half, turned the top half upside down and put sand, then pebbles. After that we added dirty water, the water was supposed to turn clear, but instead it still was dirty brown water. It took 5 minutes to at least turn lighter then it was at the start. We kept on putting the water back into the cup and then pouring it back into the bottle again and it worked well.
