I am a little confused in regards to the amount of beneficial bacteria you can have in a tank. A lot of people swear by bio balls, ceramic rings, BioChem stars and other such media insisting that by using them you can have more beneficial bacteria in your tank.
This is theoretical:
Here is why I am so confused. Say you have 10 Danios in your tank, adult sized and full grown. They produce 100ppm ammonia per week. The amount of beneficial bacteria that is needed to eat that much ammonia is 10,000. In a cycled tank you have that many in order to have a reading of zero ammonia. Now adding bioballs, ceramic rings or anything else increases the surface area for bacteria to grow but does not increase the amount of ammonia.
Someone please explain to me how you can have more beneficial bacteria that what the ammonia can feed regardless of how much surface area you have for bacteria?
