That coco brick will do approx 50liters of media once its expanded. When buying coco fiber make sure its from a good source. GH and Canna (way more expensive) make pretty good coco. Its low in salt unlike some some of the cheaper coco out there. Unfortunately the only way to test it is to soak the coco in water and use a EC/TDS pen to measure how much salt has been leached out. Now I'm not sure how much cheap coco would affect frogs but its killer in hydroponics/plant growing.
