Don't know, but when I have an emergency, need a part, can't even get a bulkhead during normal buisness hours. I have little use for that lfs. That's why I'm a proponent of supporting a lfs for days like today when you have to have something a local lfs is saposed to stock and need it right now. I'm totally done with sea, the wall tanks looked unexcusably discusting last time I was in. I'll be going to Phoenix and online for all my future saltwater needs.
