Just a small question regarding "Fully Submersible" heaters, since I bought a 250w Stealth Heater today, and I've only used the half submersible type until this day.
I'm wondering, is it fully submersible, as in you can drop the whole thing into the water, so like the temperature dial is also in the water, even parts of the power cord, or is it just to the top, just before the dial which sets the temeprature setting (where it says minimum water level)?
What is this minimum water level anyways, does it mean that it has to be submersed to this point at least?
Just curious, seems a little shaky if I can slip the power cord into the water, or make the temperature dial wet.
