What are DT's I read about folks feeding there reefs with this but don't know exactly what it is. Is it sold as DT's at the LFS or under another name what is the best brand.? Is it kept in the refrigerator.?

I don't know if i'd let DT's personal opinion on nano's have any bearing on buying his product, but if you didn't want to do it, you can always grow your own phyto, and many more varieties than you can get in his bottles.
