 Good point! It looks like other people have had similar observations with IO & RC.

Maybe its because IO is less expensive salt than others, but I think its kinda funny how IO was used in experiments to culture cyanobacteria! (Second from bottom, right paragraph).

However, after reading Bourneman's article, I think Reef Crystals may be at least a better choice than Instant Ocean.
