Hi everyone,

I have a problem with my heater. I have one that hangs off the
edge of
the tank, but it keeps slipping down too low and I feel like it's
gonna
eventually short out and fry my fish. So, I'm looking for
suggestions
on fully submersible heaters, as I like the idea of them better
anyway.



I'm rather partial to Ebo Jager heaters myself. And, just FYI, I
understand that an exposed heater dropped in tank will not fry the
fish. Someone with more understanding of electrical science can
explain this, I assume.
