Does anyone have suggestions for suitable circulation pumps for home-made SV setups? I've gone through a couple of aquarium pumps (they can't cope with the heat). I found a couple of posts on pumps (Q on old SV thread and a pump suggestion in this thread) but nothing seems ideal. I'd prefer a submersible, self-starting pump that can tolerate 90⁰C. Does anyone have any suggestions? If there aren't any pumps, can anyone comment on using air bubblers instead? I'm concerned that bubbles won't circulate water sufficiently in a large pot with lots of bags in it.
