Hello folks,
I've found only brief mention of Profile's "Aqua Soil" in past posts and I'm hoping that someone who's had experience with it will offer comment.
I'm looking for an attractive substrate to cap off the open areas in my aquascape.
My existing substrate is Flourite and, though it grows plants well, I'm not pleased with its appearance.
The Aqua Soil intrigued me because of its tan color and smaller grain size.
Is there a problem using Aqua Soil in this application?
Is it inert? Will it effect my water chemistry?
How available is it?
Any alternate suggestions?

Thanks
