What you are describing is only acting as mechanical filtration, it will not remove nitrate from the water.
So you are syphoning your tank into a bucket, but on the end of the hose going into the bucket you are using a sock? Was the sock washed in laundry detergent recently?
If so it may not be great for filtering water
Edit: ok I saw the video.
