 Half of the water filtered through this minute. In the other minute the rest of the water came running through. It started to drip a lot and than in the 50s in the 3 min it started to stop.

Conclusion:

Our water didn't really turn clear than to what we had expected. It just stayed dirty which was a shame. I thought that there was only going to be a few drops but instead there was over 30 drops. It went on for almost 4 minutes. It did start to clear up but it was still a little bit dirty.
