1.  Is it possible to add an initial ammonia source without using fish?

Yes you can. Add ammonium chloride so that levels reach 2 to 4 ppm along with FritzZyme®. When ammonia and nitrite are near 0 ppm, add ammonium chloride one more time bringing the level back up to 2 to 4 ppm. Once the ammonia and nitrites reach zero the biofilter is established and ready for animals (time is less than one week). NEVER add ammonium chloride to a tank containing fish.
