Itll be fine. just becareful of winter my 55 needs a very large heater since the basement has very very little insulation

can u use it under this under gravel?

 

[zenyoungkoh]

yes it will be okay

ok even if it is like clay soil for plants i just want to double check

I would not put it under the soil. They are designed to function in water where the heat will rapidly be carried away. In the soil there will be little water flow and the heater will overheat and also be very inefficient.
