I think the bags vary on dustiness, or I got one filled on friday after lunch,lol.
I used a large steel mesh pencil/pen holder and rinsed, what seemed to be forever. I was almost ready to quit, said screw this and put it in the tank. Was very careful and slow, the cloudiest mess I've ever seen. Got hob running and waited, cleaned hob pad(was very slimey and full) put pad back in and went to bed. The next morning it was crystal clear, moved a few things in the tank and it clouds up some but settles quickly. Now that its clear, I think its beautiful, pretty darn hard to see peewee red cherry shrimp on it, but it looks very good. Snuffy317
