(The sticky is on the Reef Chemistry Forum of RC that lists tested results of many salts, including the new I.O.. See "Synthetic Salt Mixes" sticky)

These are the exact same readings that I got with my last 3 batches of salt. Only difference is that I bought the huge IO boxes instead of the buckets.
