I have found that aquarium heaters are rather slow. The thermostats in
aquarium heaters also are not very accurate and have a large hysteresis.
I use a fairly large amount (1 to 2 gallons) as a water bath. In
Florida I usually wind up cooling the bath rather than heating it.
Either way I add water from the hot tap or ice to bring the bath to
temperature measured with a thermometer. Once at temperature it stays
there with small adjustments for the period needed for development.
Rinse and fix are not as critical. I use SS containers for the three
solutions and a few seconds in hot or cold water with stirring brings
them to temp. At one time I used a circulating pump from an evaporative
cooler with a variac to keep the water moving.

Subject: [pure-silver] Water to temp
I shot gobs of sheet film and roll film at a recent photo shoot and
now I have to develop all this stuff. I don't have lots of time so I
tend to develop a roll here, a few sheets there..
What takes up too much of my time is trying to get the water to
temperature..
Has anyone used an aquarium heater or something similar to get your
water to temp quick? I'd like something as accurate and precise.. say
+/- 1c
Thanks
