Okay, I like the look of it better than the sticky looking play sand, no offense, it looks great in other tanks. Wish there was a dark one; I think it would go better with my fishNope, PFS does not get sucked into your filter(s), or the siphon tube...if you jam the siphon tube into the sand (which you shouldn't do), it will suck some up, but if you use gravity to vacuum, it will fall right out, it's too heavy to be gravity-vacced out of a tank...
