datruedave, i stumbled upon this forum thread looking for reviews on the fluorite sand, i had to register just so i could reply to you. You're a smart guy and you know exactly whats good. the "dust" as you all like to call it, is extremely fine sand particles, which the natural seperation of large and small particles would result in the extremely fine "dust" at the bottom of the tank, the medium particles in the middle and largest at the top (takes a while to settle of course). this natural seperation is beneficial to the break down of food and waste from ammonia > nitrites > nitrates. combined with a heating cable in the sand, the constant cycling of water around the breaking down waste and nutrients would result in amazing fertilizer and potential frequent water changes. i can't wait to get this sand set up with the heating cable in my 90 gallon.
