Steve ... nobody is saying IO is no good ... at least not here I dont think ... but as somebody responsible for providing the best environment for the creatures in my care I have to look at what is available and weigh the pros and cons ... now as far as anecdotal evidence goes 64ivy at RC has started using it with no ill effects so far and he has arguably one of the coolest tanks going that I have seen ( a 500G monster of technology ) so looking at this objectively I would have to say that the evidence clearly shows that " healthy " tanks are doing well switching over and those that are having trouble in some cases have been reckless in their transition procedures.
As far as Dr Ron's testing goes ... I have not seen anything to dispute the results he achieved so far ... sure there are " other variables " that could be explored but the bottom line is that urchin larvae are more sensitive to toxins than corals and thus the perfect subject for the test ( which was for metal toxicity )
It is puzzling how some have such adverse effects and others dont and yet still some have mild bleaching but then the corals recover and then achieve even more growth and even richer colours ?
I think it is viable to test slowly ( personal opinion ) ... I have had some feedback from the manufacturer as of this posting and they will give a hefty discount for 50 boxes ( 150G box ) ... in the neighborhood of C$45 - $50/box delivered
Cheers
