Man, I can't find any white sand. The only play sand I've found so far is brown in color and I'm pretty sure that's not the right stuff. I was wondering what you used to seed it? If I go to the coast can I bring back a little sand from that to seed my sand, provided I find some. I won't be setting up my new aquarium for a couple of months, but can I go ahead and add the playsand with the mixture with some saltwater and let it set and grow then when my aquarium is ready I can add it at that time? Anyone find the sand in the TX area?
