I only buy my Kent salt at Island, everything else I buy online. I even buy my fish and corals on line instead of Island. The owners tanks look really bad, He set up a 135 gallon reef last year and from day one I new eventually it would crash, I even talked to him about it. Sure enough after about 8 months it went down hill. Now corals are dying and you can tell that he just has given up. His prices are through the roof, but being the only store on the island I guess he can do that. I moved from lemoore and would do back to back sea to stay up here. I have not been to any stores off the island. Actually I have not really been home a whole lot since I got here 18 months ago. I am expeditionary so we do a 6 months home 3 months gone rotation and I got here 2 weeks before a 3 month deployment to Saudi.
