We have been using this Phyto for many years and our coral tanks thrive on it. Our customers love it as well as Oyster Feast, Phyto Live and the Live Tigger Pods are a big help starting and maintaining a healthy reef.
I feed Phyto feast to my corals in my frag tanks as well as my main display and my corals really respond well.
Been using phyto in my reefs daily for years so my copepod population stays healthy. This stuff is super concentrated and works well! Keep it up RN!
