For dino that dwell in sand bed could you take a pvc pipe and insert one of the cheaper uv bulbs from Amazon and then go section by section in the sand bed every x seconds?
The idea being you plunge the pipe into the sand bed with the pvc shielding the uv from the tank inhabitants but still exposing the sand to uv?
