"The Whale pump" by Roman J., McCarthy JJ (2010) :
A study in 2010 has attributed to whales a positive influence on the productivity of ocean fisheries, in what has been termed a "whale pump."
Whales carry nutrients such as nitrogen from the depths back to the surface. This functions as an upward biological pump, reversing the assumption of some scientists that whales accelerate the loss of nutrients to the bottom.
They note that this nitrogen input in the Gulf of Maine is "more than the input of all rivers combined," some 23,000 metric tons each year.

A liquid high concentrate of non-toxic bacteria (40 million bacteria per ml) carefully selected for their capacity in breaking down organic matter and for transforming ammonia in aquariums. This product can be used in new or existing fresh and saltwater aquariums to transform highly toxic ammonia into nitrites and nitrites into nitrates. NITRIDAC actually causes the rapid degeneration of organic compounds reducing the build up of sediment or mud, restores aquarium walls and beds preventing the formation and growth of algae and also prevents an increase in nitrites.
