I have heard that if the ammonium levels rise because of increased fish
load, that the nitrification bacteria bloom in the water to reduce the
levels.  Others have commented that they divide rapidly and escape the
colonization of the filter.?.?.?

Actually, I found that if was helpful.  Increasing tempature may have
decreased the time required for the trace nutrients to be consumed because
of an increase in metabolism.

Did not turn green the entire 12 days that the bloom lasted.  Waited for it
to do thus though.  I was lucky this time.

Disagree - it is a planted tank and therefore the amount of decaying
material is large; i.e, tons of food for the bacteria in the filter.  Do
not know that dead bacteria "bloom."  I believe that the majority of people
would define bloom as a growth.  If, in fact, it was a "dead" bacterial
bloom then the fliter would have removed it within a day or two.

Not my intent.  I was merely responding to a reply with increased info to
see if a problem could be figured out.  Sorry if I offened you or anyone
