1.    Cyanobacterium is the group of photosynthetic bacteria that have two photosystems, that produce molecular oxygen, and uses water as an electron - donating substrate and photosynthesis - also know as string algae, hair algae, and blue – green alga.

2.    Assimilatory denitrification occurs in anaerobic areas were nitrates are reduced to ammonium (NH4+). Obligate anaerobic heterotrophs accomplished this in oxygen free zones, when exposed to oxygen die very quickly. This is known as “Ammonification,” a form of denitrification.

3.    Anoxic is a more recognized word than the unfamiliar words “dysaerobic” or the medical term “hypoxic” to represent areas in the substrate where very little oxygen is present. This way of filtering contains approximately 2.0 mg/l to .5 mg/l of oxygen and is where destructive denitrification takes place.

4.    Laterite itself is negatively charged and increasing magnitude with depth. The deeper the plant basket, the more negatively charged it becomes and the more positive charged nutrients are naturally attracted deep inside the biocenosis-baskets.

5.    Dissimilatory denitrification is accomplished by facultative anaerobic heterotrophs and lives in anoxic zones.

6.    The Liebig Minimum Law is that plant growth is determined by the one factor that is present at a minimum. That is healthy plants must have all nutrients in the correct proportions. The first five major elements are sunlight, CO2, Iron, Manganese, and Ammonium (NH4+). The law also holds true for trace elements as well.

7.    Hydrogen Sulfide is a poisonous gas (H2S) that has an odor of rotten eggs.

8.    Sweet smell; means that the clay biocenosis-baskets had no other odor than that of the ponds natural smells.

9.    The process whereby particles of liquids intermingle as the result of their spontaneous movement caused by thermal agitation and in dissolved substances move from a region of higher to one of lower concentration. Diffusion is fundamental way molecules collide and react; how food molecules approach cells, and how waste leaves local environments. That dynamic process that helps many biological functions takes place, and physical factors take place. Diffusion is a part of all ponds whether natural or fabricated, diffusion will exist to one degree or another in all systems.

10. Kitty litter and/or cat litter is not really a potting medium, but it works very well as one. Kitty litter made from calcified clay (which is mined from the earth, cleaned, baked, and pulverized) is best because it has not been chemically treated or deodorized. Avoid products that contain anything with none clay materials in them. Kitty litter is as good as clay soil at holding nutrients, yet it will not muddy pond water if disturbed. It will not float or clump.
