Tahitian Blend or DT's ??

[Pansy-Paws]

I've tried both, and now use Tahitian blend exclusively (and available locally from Jack and Wendell).

I didn't really notice a lot of difference in the tank with the two approaches, but DT's is more expensive ...

My comparison was by watching fan worm populations, since I don't have a lot of other filter feeders. So, take this observation with a grain of sand ... other organisms may respond better with one or the other
