I may have gotten the nomenclature wrong but it was something along the 'reef' line and the bucket had a different colour as mentioned above. There were two pails stacked on top of each other, unmistakeably IO and the 'new' one had the additional information on it regarding being more suitable for reef tanks with the elevated ca, mag levels.
