I'm sure you could use Texas gumbo in your aquarium, but it's properties
would be somewhat different from laterite.  The black gumbo where I live is
built up from grasslands resting on top of limestone bedrock.  It contains
a pretty high percentage of CaCO3, and is very hard on acid-loving plants
like azaleas.
