I'm new to this forum, but I'd like to know if anyone has attempted an Indian River Lagoon Biotype aquarium. I just bought a 75 gal. and I was thinking about trying to set it up with some live coquina rock, oysters, and various seagrasses. The specific gravity needs to be about 1.020-1.02 5 to match my local conditions here in Palm Bay, Fl. If anyone has tried this I'd like to hear about what went right, wrong, etc.
