I know that the nitrifying bacteria mostly cling to surfaces.
I was wondering what if any bacteria do live in the water.
Where would I go to learn this?
TIA
Thanks. TKOS I wonder how I can find if specific bacteria are typical of "used" freshwater fishtank water.
For that matter where could I find what other oganics,minerals, etc are in there. I am googling what I can think of.
