One bag of 20 g Barley Straw Pellets, Ku Barley Straw Bacteria about 2-3 g and a Hook are for cultivating a good microorganism and ecological environment‧
1 tea bag of each to use to help cycle your shrimp tank using Vins methods. Simply place in tank, hanger included. You can leave this in the tank indefinitely to grow biofilm, but I normally remove them after about two months when they start to get a bit stinky.
