Didn't you have any problems to fix that heating element in the tank? Here in Belgium , the heater is supplied with 2 big suckers. They even don't fit in that tank! So , I had to fix the heater with some rope .... Time to etch a pcb is the same like yours.

I've just etched a small board (ARM JTAG interface) using the new tank
and it looks very nice. The instructions suggest two minutes to warm
the solution after switching the heater on; I used about five minutes,
and at least 20 minutes is probably about right. Because of the low
temperature etching took about 15 minutes.
I used my usual photo-etch technique with artwork produced on an HP
DeskJet 5940 inkjet printer using Premium JetStar film. The text on
this board had the default 5 mils line width, and came out perfectly.
Narrowest track size was 12 mils, though.
Here is a photo of the PCB:
