Seeding the biofilter can be done with Bio-spira. All it needs is substrate for the bacteria to grow on. I use Seachem Matrix in a media bag and put it into a HOB filter. Add a bottle of Bio-spira and I'm good to go. Never had a problem with ammonia using this process. Most pet stores carry ceramic media (Fluval makes ceramic rings that are similar).
