MARSH Salt study

[Murminator]

I used to use Red Sea then after boxing day sales I switched to I.O and I did notice a difference right away thought the corals were mad at me and they never really fully recovered from it and it been like 9 months, and I got cyano not long after that I never had before... and still have. So when my last pail is done I was already planning to switch back to Red Sea.....I was thinking about switching to Reef Cystals after what Rusty shown me on the pail saying it works the best with tap water.
