Mar 16, 2007· I used silica sand (allegedy cleaned...blah blah blah) to set up one of my tanks. If I remember correctly I seeded the silica with a couple bags of aragonite based live sand, so the sand bed is approximately 80% silica. I fought (and still fight on occasion) diatom outbreaks much more than my other tank which is %100 aragonite.
