AALSO Test study Questions and Answers Verified
100% Correct
Ammonia/Ammonium
Toxic to fish this increases with pH. Ideal level is 0mg/L. NH4+ or NH3.
Nitrification
The breakdown of ammonia into less toxic nitrogen based compounds through bacterial
processes.
Nitrogen Cycle
Elemental Nitrogen -> Marine Life -> Waste and Bacteria Ammonification -> Ammonia NH3 ->
Nitrifying Bacteria + Oxygen -> Nitrite NO2- -> Nitryfinig Bacteria + Oxygen -> Nitrate NO3- ->
Plants and Denitrifying Bacteria -> ...
Ntrite
Toxic to fish, can impair the transport of oxygen by red blood cells. Ideal level < 0.5mg/L.
NItrate
Less toxic to fish. Able to be off-gassed or assimilated into plant life as nutrient. Ideal levels <
50mg/L
Ammonium Chloride
Used to start the nitrogen cycle in new tanks.
Coral and Amphibians Nitrate Toxicity
> 20mg/L
How do you reduce levels of nitrogenous waste?
