Yeah, I have heard Phytofeast is really good. I have never tried it though. I recently tried Seachem Phyto, and I gotta say. I love it. I use it 1-2 times a week. I do a little less then daily amount in a small cup, and dilute it with tank water to have a larger amount to spot feed, and the corals just absolutely love it. They react super strongly, especially Zoas, but I think my Carnation really benefits from it. It has a large mixture of species and sizes, but I am not sure if other brands are better or not, but for the price, and long shelf life (refrigerating it) I don't think you can beat that.also for food, i see many people saying they use roti feast and oyster feast, but no one really mentions phyto feast. Can phyto feast still be used?
You could also consider live phyto.
