Yeah, it is an advantage of living here in the Bahamas...Everything is at your finger tips. A friend of mine just went out yesterday and collected some corals. You can walk on the rocks and pick up thousands of blue hermits and snails that work miracles. I mean, this same guy had hair algae so bad, you couldn't see in his tank. He stopped by the shore, got about 50 or so of these little snails, and in less than 18 hrs, you couldn't find any form of algae anywhere. It was like he boiled everything in his tank for hours it was so clean. I had to see it to believe it. Yeah, but in reference to the sand, sand is in an abundance here...From pink fine sand in Harbour Island to crushed corals in numerous places. I'd be more than happy to send anyone sand. I don't know how expensive it would be to ship, but the sand wouldn't cost a dime. I'd be more than willing to send it. I'm always looking for another excuse to jump in the water!
