hi I was thinking of getting either a Flourite or Onyx sand as a sole substrate for my 4 ft tank. From the Seachem website the impression that I got was that they are both essentially the same apart from colour and buffering capacity. However on paper it seems different. This is from their website: (http://seachem.com/products/product_pages/Flourite.html)

Concentration of nutrients in Onyx Sand™
Aluminum 822
Barium 5
Calcium 197500
Cobalt 4
Chromium 10
copper 4
Iron 2846
Potassium 417
Magnseium 115400
Manganese 43
Sodium 135
Nickel 7
Vanadium 8
Zinc 23

Concentration of nutrients in Flourite™
Aluminum 10210
Barium 124
Calcium 195
Cobalt 6
Chromium 13
copper 17
Iron 18500
Potassium 2195
Magnseium 2281
Manganese 64
Sodium 223
Nickel 12
Vanadium 15
Zinc 29

Units=mg/kg, source: Plasma Emission Spectrometer, EPA Method 3050, Univ. of Georgia Chemical Analysis Lab

Particularly the iron content in Flourite is alot higher than Onyx (on paper). Does anyone know the correct way to interpret this data? I am not a scientist and can't draw any conclusions and any help would be greatly appreciated. Thanks alot guys.
