Nitrogen (N)
• The nitrogen cycle is complex in part because of the many chemical

•
forms of N: Organic-N; NO3; NH4; gases N2, N2O, NO + NO2
(=NOx).
(NO), Nitric oxide
(NO2), Nitrogen dioxide
(N2O), Nitrous oxide
(N2) diatomic oxygen
(NO2) nitrite
(NO3) nitrate
(NH4) ammonia, (NH3-) ammonium
• Accounting - distribution of N in grams times 1015.

Nitrogen Pathways and Reactions:
• N2 to organic-N; called "N-fixation" (plants and

humans)
Organic-N to NH4+ ;"mineralization" (by
bacteria and fungi)
NH4+ to NO3- , producing NO2 and N2O;
"nitrification" (by bacteria)
NO3- to N2 , producing N2O ; "denitrification"
(by bacteria)
NO3- & NH4+ to organic-N; "photosynthesis"
(uptake by plants)
Eduction pipe lift pump
Invented by German mining engineer Carl Loescher in 1797
For tropical reef aquaria

III. Animals and plants
• A. How many?
• B. What kinds? - Fish, crabs, shrimp,
barnacles, oysters, sea shells, anemones,
gorgonians, starfish, urchins, worms, sand
dollars, algae (sea weeds). Avoid: sea
cucumbers, sponges, and large fish.
IV. Maintenance
• A. Evaporation and water changes
• B. Cleaning
• C. Feeding
• D. Problems and tips
– 1. Cloudy water and mortalities
– 2. Diseases and copper
– 3. Water color
VI. Collecting your own specimens
• A. Collecting
– Temperature, aeration, biomass/vol.
• B. Handling and transporting
– Containers – dark and insulated
VII. Maintaining and feeding
• Community tank
– No questionable additions
– Do not feed for three days
– Feed M,W, F only
– No uneaten food, dead or decaying matter in
tank at all
– Return all unhealthy to nature OR have
intensive care tank
