Does More Media Always Equal More Bacteria?

If someone has a 100 g tank with 1 guppy and 100 g tank with a common pleco would there be more bacteria in the tank with a pleco because there would be less ammonia to feed the bacteria in the guppy tank? So even if you put a lot of media in a filter it wouldn’t mean all of it has bacteria on it if the bioload is very low?

I would agree with that, yes. It's like talking about any food chain. Any population (in this case, bacteria) can only be sustained to the extent of their food source (in this case, ammonia).

yes, the amount of BB is dependent on the bioload.

but the bacteria would be spread out, albeit unevenly through out all the filter media. since the water flows through all the media, and the nutrients aren't immediately absorbed/consumed by the first few bio media it comes in contact with.
