Is there a reason that so many folks dose phyto to a tank? I have not dosed phyto to mine and I cannot see any benefit. Corals don't eat it, according to most research that I have read. I have thriving copepods. There are several types of feather duster worms, large and small that came in on live rock that I added over 9 months ago that seem to be doing just fine. So, what's the deal? Is there really any benefit to adding phyto to the food regimen in most reef setups, or is it something that only a few organisms require?
