I wonder if different bags have different amounts of dustiness? I used Safe-T-Sorb.
I did have quite a slurry of muddy water when I set mine up. I was ready for it, and 'rinsed the substrate in the tank'. It only needed 2 changes of water. First one (6" deep) was a muddy mess. Second one (also about 6" deep) was noticeably cleaner, though still muddy. I filled both of these stirring the material as much as I could. Deliberately MAKING a mess. Then draining.
The third fill was done slowly. I put the Safe-T-Sorb bag in the tank and filled by running the water slowly over it. Sure, it was a bit cloudy, but nothing that I would not have put fish in. It was a lot clearer a few hours later, and really clean the next day. I ran the filters for a few days, then cleaned them. Lots of silt.
I re-scaped, again clouding the water, and did a water change, but the water was not really too bad. However, I had been deliberately messy again (I think I missed out on making mud pies as a child) so I took that opportunity to get rid of some more dust. There was not much left.
