I've never used sand before, but if I get a new 10/15 gallon aquarium, which I'm planning to do, I'd like to.
How does one go about seeding a new tank with substrate from an old tank? My 5 gallon has gravel in it. If I didn't want the gravel and the sand in the new tank to mix, could I just, say, fill a terra cotta pot with gravel and place it in there? That way, it would be easy to remove the gravel when the tank was cycled.
Have any of you mixed substrates before? I was thinking of maybe using both sand and gravel in the new tank. Is it a bother to clean that way?
