Autotrophic bacteria is mostly in the substrate,.
caution: just because I have an opinion isnít proof I know what I am talking about!
Perhaps you can expound on this - then we shall see if you know what you are talking about
How would having 2 filters offer one bacteria an advantage?
How is the competition for surface area any different with 2 filters versus 1?
If autotrophic bacteria is in fact primarily in the substrate, how do the filters have any impact on that? And how is there competition for real estate if one prefers the filter and the other the substrate?
I think that there is a point at which theory loses practicality, and in my opinion this is a perfect example. I think that this "greater understanding" about the ins and outs of the bacteria is largely irrelevant to the vast majority of keepers and their tanks. It may be 100% correct, or maybe it's not - I don't know. However, one thing of which I am certain is that whichever the case may be, it will make absolutely no difference to my fish tanks or how I keep them. I run multiple filters on each tank - I don't have any issues with ammonia or nitrite. Really, that's all that matters - 0 is 0. Keeping fish can be as easy or as difficult as we want to make it for ourselves. There's nothing wrong with getting lost in the science - we are all in the hobby for our own reasons, though they can vary greatly from keeper to keeper. But at the end of the day, what's most important is 0 ppm ammonia and 0 ppm nitrite. Fish keeping is not rocket science and nature needs no direction from us.
