Substrate Heater Question

This is my first time using a substrate heater. It's been set
up for 3 weeks. Heavily planted and a 4 inch depth of Flourite.

The question I have is, is it normal to once and a while see
a big bubble float up from the substrate. And when I planted
the set up a week ago, every time I would dig a hole for a
plant, bubbles come flying up. TIA
