There must be an anerobic spot in your gravel or sand ,give it a thorough
vacuming or raking and you will see a load of gas bubbles escaping the
substrate then do a large water change to remove any hydrogen sulphide
build
up in the water.

Just my tuppence worth, but I wouldn't rake it. I would use the vacuum tube,
driving it deep into the gravel systematically and jiggle, this will ensure
the H2S is taken away by the vacuum and not allowed to dissolve into the
tank where with only a few ppm it will kill fish. As someone else said this
is not a long term solution though.

Cheers
