Looks like IO has gotten much better than in the past if the results posted are consistant. I've been using DD on my 25g because I didn't want to have to dose anything with a tank this small and parameters have so far been perfect out of my last 2 buckets. Everything thrives and no algae but on a tank this small a bucket lasts forever. On my new 90g I'll have to give IO another try. I used it about 5 years ago on a 72g and had to dose all the time even with mostly softies and only a couple LPS and had algae problems until I switched salts.
