You want completely honest? I've used both, and frankly, I do not see any observable change from either compared to using neither. I'm using DTs because I got a free sample at IMAC, and it is not doing harm. Though I wonder if the green algae on the glass is growing faster because of more regular use of DTs.
But I honestly do not see any observable change in corals soft or stoney, or clams, or sandbed critters even after regular use compared to not using any for a lengthy period. The same goes for the 6wk period a while back when I was using PhytoFeast.
I can't say that I'd buy a phyto product in the future. I supposedly have animals that would benefit from phyto, but I haven't seen any harm to them when I was not using it.
