A full gallon of the 5 species blend (Tig, Tisbe, Apo, Oithona, Euterpina). Best value per pod we sell. This is the one for large systems, multiple tanks or anyone trying to keep a couple of mandarins fed for the long haul. Everything is cultured in house in Vermilion, Ohio and bottled fresh the morning it ships. Orders go out Monday through Wednesday only so nothing sits with a carrier over the weekend. 100% live arrival guarantee, if anything shows up DOA I reship it free, no photos or claim forms needed.
