Yes, that is why I stated that bacterial colonies vary greatly from tank to tank. There is a test now for bacteria in the tank and it's sometimes all over the map when looking at people who posted different tank breakdowns
One 3 month old tank bacterial colonies may differ significantly to the next one. Maybe it is by chance? Maybe it is about early stability that let the right ones grow? Maybe it is about what happened to be introduced on a snail and frag plug and perhaps the right one established? So much we don't know yet tbh.
Regardless you want your No3 and PO4 stable much like Alk. PO4 more so.
