Okay, I don't sell anything... I represent something. That means I go to the stores, do the trade shows, do the grand openings, answer product questions, teach the employees yadda yadda.
Open your DT bottle, does it smell good? It indeed uses a freshwater species of phyto called chlorella that has a more pungent smell than the others.... but it shouldn't smell like death. Only death smells like death.
I don't represent Reef Nutrition either, but I'll tell you to use their phyto over DTs, even though it has a lot of dead cells, it has a preservative that will prevent rot. You want a preservative over rot.
Pick a single species bottled product. Your product will be alive when you use it. It will smell nice and fresh. You mix too many species in a small bottle and they would attempt to kill competition to ensure their own survival. It's called allelopathy.
