Phyto-Feast or Phyto-Feast Live?
Phyto-Feast Live has the same algae as Phyto-Feast but is handled with special care. Phyto-Feast Live is harvested and shipped fresh each week and has better short-term cell viability. Phyto-Feast has better long-term nutritional stability. Both are equally good for your aquarium.

Phyto-Feast is a preserved product available in 6 ounce, 16 ounce and 32 ounce bottles. Phyto-Feast contains whole and intact biological organisms in a media with benign food grade additives. No phosphates added. For longest shelf life, all Phyto-Feast should be refrigerated before and after opening.
