So I have had a reef tank for over 2 year, but I was in an area where i pulled my water and coral from the ocean. Now I have to do alot of work. I am in the process of upgrading my 65 to a 90 gallon, which was up for only 3 months. So it is like I am starting it from scratch. Get used to seeing tons of questions form me. I have never done much maint. and most of the livestock I have had was caught and kept in ocean water. So, all the specifics elude me. Anyway, I look forward to your help.
