unbelievable looking tank i dont recomenned putting gravel on top of the heater most manufacturers tell you you shouldnt doit but maybe if u put it in the corner verticly it will be a little better it wont be hidden but atleast it wont go across the whole tank but i think you did an amazing job on the tank
beautiful tank and for the heater i would just get another piece of wood or a plant to put in front of it but do what u will its ur tank and if u like it leave it cheers
