What if you took what we know about the sea sponge and what we know about the cleanliness of our oceans? I'm purposing genetically modifying a type of sponge to produce a super species that is capable of breaking down hydrocarbons and using them for energy. In a way, the harmful products in the oceans that are life-threatening to every other animal could be a food source for this new sponge. After the sponge has proven to be self-sufficient and thriving on a toxic food source, this kind would be introduced to the problem areas under the sea: dirty harbors, suffering coral reefs, and oil spills. Because sponges reproduce by budding, it wouldn't need constant upkeep or human involvement beyond introduction. Let's assume the sponges thrive off garbage, chemicals, and oil. If they run out of these things and die off, their job is done. They'll have served their lives as beautiful accents to the ocean floor while improving the environment for the underwater world.
