I wonder if this could be be my problem.

My LFS get their water directly from the ocean. I did not have this problem until I did a major water change. My fish are dying off one by one. I just learned that RED TIDE is an issue on our area. I found this out from a freind and confirmed it on the State of Florida Fish and Wildlife Instututes Web page. I called the LFS and they said they are not aware of issue with Red Tide nor do they have a test for it. They suggested another water change. DAAAA, why would get the water from them when there is a posting of Red Tide in the area and they don;t even know about it. I just installed an RO/DI unit in my house but the ammonia levels are very high, all other parameters are great. I am going to try adding Ammonia remover and mix the salt myself and try that. This is making much more sense to me if the red tide is an issue. What does anyone else think.
