I think my multimeter gives a solid "1." as infinify. I'm going to see
if I can get a resistance reading while trying to find the breakpoint
in the cable. Don't worry, I'm not planning to reuse it again ;-).

Now that it happened once, I'm a bit reluctant to replace the cable. I
don't want to tear down my tank again just because the silicone cable
is too fragile for normal use. Maybe I can try to place some sort of a
grid on top of the cable, too make sure I'm not piercing the cable
with a sharp stone or while vacuuming the substrate etc. Is there
anything against using an aluminum grid in the tank? Can it give
poisonous metals into the water or something?

Greets,
Hendra
