Phyto-feast arrived well packaged (shipped insulated & cool) and fresh. The squeeze bottle makes adding this to the tank a breeze. The feather dusters seem happy. The company was kind enough to include a free sample of tiger pods which were all alive/swimming around. Will order again!

Love Reef Nutrition products, always high quality and they seem to have better shelf life than some other popular brands that I’ve tried. I do try to use other brands occasionally for some bio diversity but my go to is Reef Nutrition!!!

Possibly the best Phytoplankton out there
I really like the reef nutrition brand phytoplankton because it seems thicker (more concentrated) than other brands allowing it to sink quickly into rock work. Also, I have never received a bad batch and The shelf life is really good. I like the bottles the small size comes in because you can just give them a quick squeeze and watch the concentrate sink in. I wish the larger sizes were packed in bottles with squeeze caps like on water bottles. (hint:they would probably sell more because people would use up more quickly with quick squeeze applications). Overall it’s my favorite!!
