I just find it breaks down allot when rinsing leaving you with less. But everyone has their own methods. As for mosses I can't help you. My plants are all very low tech low light which moss doesn't thrive in. Many people in the native fish community use plain old dirt from their back yard as a substrate, I'm not sure how well tropical fish would like this. I guess if you capped it with sand or something it could work. But take that with a grain of salt.
