I'm starting a new little tank here at college because I miss being away from it. I have access to sand from the bahamas at my LFS in FL that could easily be shipped to me here in SC, but I am not sure. I have used it on my other tanks, and I use it for looks only, but I have been thinking about the 'southdown' play sand deal. Is there any opinions on what would be a better choice for my small setup?
