I don't want to be critical, since my 1st saltwater tank was done the same way...lol. I did not know any better and did not take the time to research. After I lost some nice fish, I realized something was wrong. Did my research and got better with time and experience. I'm sure this guy is probably going to follow a similar path if he stays in the hobby !! It's all about learning as we go. I do feel bad for the losses incured from these type of mistakes, but lets keep it real, the long supply chain to the LFS is not that perfect either !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
