cycling ideal temp

is there an ideal temperature for cycling a freshwater tank?

From what I've been reading recently it seems warm speeds up the life cycle of the bacteria but you have to make sure that you compensate for the extra oxygen being used. Perhaps low to mid 80's with a bubbler? Of course if you have fish in teh tank already, many of them will not tolerate mid 80's temps for long.

I go into this issue in the article on bacteria
explaining the role of temperature and pH in cycling.

But take ladayen's caution seriously, this assumes no fish, i.e. fishless cycling. You can't go messing around with water params with fish present.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

For my $.02, even assuming a fishless cycle, I would culture the bacteria at the same temperature that they will live in with the fish because any gain at higher temperatures is short lived and too slight to bother about. So 76-78 deg F should be fine.

Kept my temps around 80-82 degrees. Since cycling, I have lowered it to 78 degrees, and I have had no problems at all.
