Crystal Sea Bio-Assay

[Fishster]

I have been using IO for a long time and have had no problems. But when I am done with my current supply of IO I will be switching to Crystal Sea. The reason is I will never know what I am missing unless I try. It is my belief that a healthy reef is as diverse and full of life as possibe, and if this salt is more condusive to that then I think it is worth a try.
