Although the book cover gives the title as Twenty Thousand Leagues Under the Sea, the title page titles the book Twenty Thousand Leagues Under the Seas; Or, The Marvelous and Exciting Adventures of Pierre Arronax, Conseil His Servant, and Ned Land a Canadian Harpooner.
A man-made pond made with a pond liner has no soil â so one source of micro-organisms is missing, especially if you keep cleaning the pond liner. Most ponds have few stones and few plants reducing the number of micro-organisms even further.he use of the word ânaturalâ here refers to the pond filtration system, not the esthetic look of the pond. Iâll deal with esthetics in a future post on how to build ponds. In a natural pond the water, soil, plants, and animals all live in harmony. No one comes along to clean the pond or to aerate it.
Place a pond pump with a bubbling fountain head in the center of the barrel so it is resting on top of the gravel. Adjust the fountain head so it comes up about 3 inches below the rim of the barrel. Thread the pump's electric cord through the hole in the side of the barrel and to the outside.
