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.

Thanks,

Chris


Unlikely that your fish would be harmed electrically, it would be more of a risk
to you when you stick your hand in the water. However, these hang on back heaters
tend to be cheaply built and more failure prone than the submersibles, even under
the best of conditions. If you are interested to buy a new heater, my suggestion
is the Hagen Tronic.

For any heater, they will work better if the heating element does not too directly
warm the temperature sensor. You can minimize that problem by locating the heater
in an area of water circulation. For submersibles, you also have the option of
mounting the heater at a 45 degree angle or even horizontally in the tank.

Some of my Hagen Tronics are for ever slipping down into the gravel...we
clean the glass and suction pads, stick them back up...wait 5 mins and
hey they are back in the gravel (but only in the planted tanks - doesn't
seem to happen in the Malawi tank).

My small tanks I mount the heater vertically - seems to work better that
way - by this I mean up to 15 UK gall

Just my 2p worth
