This is my first day with SMS(completed substrate change 1:00AM this morning). When I woke up later this morning, I went and put some nylon pantyhose (g/f' kindly donated an old pair) over the end of the siphon and used that to get the fine dust that was sitting on top this morning. That worked great.
yes, I still get a little dust if I poke around in there, but nothing to bad.
Overall this my first SMS attempt is less cloudy than the first time I used flourite.
