Can you verify if that were really the root tabs that "exploded". Like MrGreen :icon_mrgr I have noticed blackworms and such dig out little mud mole hills that indeed look like mini volcanoes, although they did not cover the hole tank.
Maybe the root tabs raised the concentration of salts or some other elements in the substrate, and the worms went crazy after that?
