The only thing I don't like about the study is there was only one tank of each sample. Something could have happened to that one IO tank that made the results what they where. I would like to see this test at least repeated once before I start throwing away my IO. Now, would I buy Reef Crystals? Sure, just because I will normally go with reefcrystals if it is available and not $10+ bucks more a bucket.
I have set up enough tanks to know that sometimes a tank you start up will have some problems that others will not. I set up a half dozen tanks once, all 10 gal, all using IO, all using the same sand and all the liverock was out of the same tank that I had for well over a year. This was a quick breeding set-up. Light was the same. Bioload was very close to the same, but I had one tank that always had cyano in it. Why only one?? I have no clue. If that could happen to me, why not them?
