	I'm not sure I agree.  If placed in the UGF tube it would probably
heat the water in the tube to a temperature higher than the ambient tank
temp. This should cause water to rise and thus suck water through much like
a UGF w/ a powerhead or airstone would. I think the theory is that this
will cause a much slower flow which will be beneficial for substrate
nutrient flow but not have all the badness generally associate with UGF.
I think what I would prefer is to put a heater in the 'updraft' tube but
run a power head in reverse.. ie., create a RUGF w/ a heater. I've not tried
either myself. The Krib has an article on the subject..
