Re: Soil Substrate

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.
