One of my tanks has a sand substrate and I want to blend it with fluorite or Eco-complete to give my plants a more nutrient-rich medium to grow in. The fluorite I've seen for sale comes as granules of about 3-5 mm. I prefer the look of the sand. Also, I know that with substrates of mixed sizes you get the small particles settling. So my question is, has anyone ever used crushed fluorite (or Eco-complete) or have opinions on this? I want to get the grain size of the fluorite about the same as the sand.
