reef crystals VS. kent sea salt

[canadawest]

I have been using Kent salt for the past year with no problems. It mixes well and is one of the cheaper brands.

J&L carries the 200gal buckets of Kent for $59.95 and Instant Ocean for $64.95.

And once a year J&L puts the salt on sale, bought my current 200gal bucket of Kent for $49.95!

Reef Crystals seems very expensive to me, and doesn't appear to offer any benefits over Kent or IO.
