I am not sure if this is something that you see out here but here it goes. Almost every LFS out here that I have been to has their own premixed water that you can buy but they also have ocean water. Now they get this water from two places: One is from Catalina island and the other is from the Scripps Ocean institute. I know quite a few people who get their water from Scripps and it is actually free so +1 for not having to buy Salt. I was thinking about going up and buying Aquarium World > Home water because they have it on sale but Im not sure. Thoughts???
