To the best of my understanding no the strains are different. Dt's has N. oculata, N. salina, and Chlorella. LLife has Nannochloropsis, Tetraselmis, and Isochrysis(unsure of the species of each). I a pretty sure the micron size diversity is similar bewteen the two products, but I just like adding a little diversity to everything. If I had to feed one I probably would go with Dt's just cause it is live. I used Golden pearls in my old tank with good luck also.
