Active flora over dirt?
I have a 29 gallon tank set up with dirt substrate and River silt for topping. Thinking when I move it would be easier to set it up using Active flora. To prevent recycling will save 1/2 of present substrate and use it as base substrate when set it up.
I am wondering if in time if the Active flora will mix with with the dirt substrate? If yes then I need to use River sand again for topping.
