it might be good if you help give us another experience of what happens in the 90s.

Oh sure, easy to say when it's not your tank.
Anybody else have any input on my tank being 90*F?

As far as I know, the high level pH is usually of an orange hue. I started out with a pretty high pH myself, at about 8.2, and even then it was browny orange and not at all pink. I have had it come down through the complete range to 7.4 (lowest on the card), and it always remains of an orange tint.On my API high level pH test kit, the color shows up as a bright pink
Yes, there are two species involved: Nitrosomonas spp. (these oxidize the ammonia into nitrite(NO2)) and Nitrospira spp. (these oxidize nitrite(NO2) into nitrate(NO3)). Both species are chemolithoautotrophs, which are anaerobic bacteria that avoid light and are unusually slow growers. Bacteria that are "lithotrophs" (the name derives from "eaters of rock") are ones that process inorganic materials (ammonia, calcium, iron, etc) rather than organic (carbon chain based) materials like heterotrophic(eat living or dead organic materials) or saprotrophic(eat dead or decaying materials) bacteria.speaking from working in a kitchen (as a chef), most bacteria stop reproducing (or at least slow right down) below about 5 degrees C, and above 65 degrees C, although higher is needed to kill them, so reversing this (as you want the bacteria to grow, not die or stop) It would make sense that the optimum temp would be directly between those 2, at about 35 degrees C, which is.... 95 fahrenheit. although I have no idea of the actual prefered temps of the specific bacteria involved, does anyone know the scientific names of the bacteria you want to build in a tank?
This is all a fairly well studied thing: The ideal pH for fastest growth in fishless cycles is 8.0 to 8.4 and the temp I like to recommend is 84F/29C. WDright, can't find anything on Nitrospira but Nitrosomonas apparently likes a ph between 6 and 9 (so most aqauriums should be pretty safe there) and a temp between 20 to 30°C (68F-86F) So I guess going up to the 90s will start to slow it down.
I'll see if i can find info on the other one. Might narrow the optimum temp range a little more
EDIT:
nitrospira has a wider temp range, going down as far as 15 C. and up to 30. So the range can be kept where it is. But it prefers a higher Ph. But I guess you're kinda stuck with the Ph,or at least it's not worth worrying about. (it likes 8 - 8.3, which isn't really very nice for most fish)
