Hi Tomoko,
I'm familiar with the Profile products, but this is not
it. I actually use the Profile Soil Conditioner mixed with gravel in one
of my current tanks; it is the hard, kiln-dried clay. These other soil
products are very different from the Profile. One of them is made by
Hoffman, and the other is from a small company in south Georgia. Both are
black like potting soil, but made from a mixture of clay and sand or peat and
sand.
