For the HOB breeder boxes like the Marinas do those need to be up and running before shrimp go into them? As in, do they need to be 'seasoned' or since they run off the tank water itself is that good enough along with some mosses or plants from the tank? For substrate I'd hate to use substrate from the tank itself and stir up a bunch of debris so as long as it's substrate that doesn't leech ammonia it should be ok right (the same substrate that's in the tank, just not straight from the tank)? Or no? Thanks in advance!
