I was about to say this. I feel that anything heavy enough to sink to the bottom would be grit, therefore it's working perfectly. Any floaters would be minimally damaging to the paint compared to whats on the bottom of the bucket. Also very gently dip into the water and don't move the bucket around so you don't disturb the grit layer on the bottom.
