I've been following this list for quite sometimes now and found it very
useful. I think it has more info than all the books I've read about
maintaining a planted tank.
I've read many posts about the different substrate. However, I
think I'm planning to go about using topsoil mixing w/ vermiculite, a
layer of sand and finally covered w/ gravel. I have this one thing about
topsoil and the possibility of contanminations and toxin in the
topsoil. I've seen a bag of topsoil at my local Eagle store but it
doesn't say anything about content of the soil. Is there a way to
sterilze the topsoil???
Would somebody please enlighten me about this question and maybe
suggest other possible substrate material?
