The black stuff is where the sand has turned anoxic. Its not good but as long as it is only a bit it wont cause any problems. I take it it is a DSB? I've run DSB's for years and never got them to run well long term. I think they need to be turned over A LOT by critters to work properly.... and we rarely run them with enough critters.
