Speaking of H2s, could that be what the bubbles are coming from the bottom of my pond? Pond is about a year and a half old. Not lots of bubbles but have always noticed a few since the pond was new.
We are in an area with shallow coal seams and some shale. Never hit any while digging the pond but I wondered if a coal seam could be deeper and offgasing a little...... methane??? Or is it just a normal occurrence to see a few bubbles coming from the bottom in a pond?
Just curious. Doesn't seem to have harmed anything that I know of.
