## Description

Seachem Reef Phytoplankton 500 ml, marine aquarium invertebrate diet : desertcart.ae: Beauty

Review: Used it for years now... - Have used this for years with all my fish. I add a capful with a few drops of garlic oil to my daily feeding of frozen mysis shrimp and flake food and let it soak in a small container overnight then feed the fish. Have never had any sort of sick fish and I think that this helps to keep them healthy.
