So how many do you figure would be needed on a certain size tank?  Seems
like as long as your heat loss via the PJ is greater than your heat input
from the air and from devices, you could, over time, reach the desired
temp.  Time should not be a limiting factor in an aquarium setup.  A
gradual change would be preferable anyway.
