My theory is simple. The company says don't use eco-complete to cap because then you wouldn't
purchase a few more bags for that new tank. I am going to Petsmart today to read a bag again
As I stated earlier, since learning about Mineralized Topsoil I will be adding it to my repertoire.
Rinsing your yard dirt to remove wood and floaties, plus sifting out larger pieces of rock, etc would be
a good idea. I have seen people do everything from shoveling dirt straight into a tank to boiling it on
the stove first. Do a quick forum search and most other questions will be answered.
