ive used IO and that worked ok not that fantastic good for fish only and then did 3 buckets of crystal reef IO every bucket had dirt at the bottom of every water change i did and slow disolving. I have been using oceanic for the past 2 buckets always clear and always keep my calcium up at 420 and KH 10 and less salt creep then with IO. also have goin through 2 50 gal bags of pacific coast import salt now thats bad salt so in PH and trace elements and calcium. used coralife thats bad salt alone with red sea now thats worst of all. really it what you like and think works no salt is really that much better they are all made the same with all the same elements. i will just stay with oceanic |
