Has anyone used Dr. Earth's 728 or 807 organic potting soils for substate? I'm having trouble finding MGOPS that is in good enough shape to use.
Go for it, we need more people experimenting to further the hobby.
Rinse or screen out any floaters, pack down 1 1/2 of the dirt, add a sand CAP of 1 1/2 -2". Then plant it as heavy as you can. If you don't have all the planned plants for the tank. Put in what you have and loaded it with either Hornwort or Water lettuce until you cycle and get the permeant plants. See my Toxic Ten link for more info.
