oh yahh.. When he goes for a run it's a wake of particulates behind him, like a horse down the dusty trail! The beauty of grade 2 pfs.. It's small enough to be a good sand substitute but big enough it won't get kicked up and you can even vacuum it with light suction and it won't get sucked out of the tank.. Will never get close to your filter. I have my penguin intake about 2" off the substrate, not a problem.. I think the gas pockets thing is more a myth than actuality.. Every couple months just probe the substrate and stir it a bit and I can't see it ever becoming a problem.. It's good to stir up sand a but anyways, stuff will get trapped in the first inch or so..
