I recently purchased TLF Julian Sprung's Sea Veggies (purple) on Friday and after one use I was instantly turned off of the product. This isn't a post to bash the product, just to inform other reefers that have an aggressive algae eaters, like my purple tang, to stay away from the product. I instantly noticed that the algae easily breaks up after a few bites and after 2 minutes the algae sheet was in nearly a hundred pieces floating around my tank. Just a forewarning to other reefers.
