| Interesting. ORP meters will be effected by oxygen levels, and therefore water temperature and by pH. Did the kitty litter change the pH?
If the man already had a high end filter what did he need kitty litter filled plant baskets for?
And how did they manage to get started with the main filters already in equilibrium with the nutrient source?
If the ammonia is gone can it be 'more' gone?
And if the kitty litter baskets have special heterotrophic species that are better performers than traditional nitrifying species how do these nitrifiers manage to survive in the natural process of competitive exclusion?
And if this species can process ammonia in winter and stays robust as a result, where does it get this nutrient from as the fish are producing a mere fraction fo what they produce in summer?
I know I should stop, but I can't help myself----
