hey, i just placed and order for vigor, stout, bacter crystal and crimson. I went back to the website and seen stout is out of stock, did i get the last one or did it sell out while i was placing my order. Stout seems to be getting a little hard to get a hold of. Im setting up a cbs fluval nano shrimp tank and want some good stuff to add to the substrate. So any free samples to help me start out would be much appreciated.
