Harmful elements dissolved in the water of the aquarium, including ammonia, phosphates, and nitrates, are processed with the help of the organisms that are introduced from the live rock into the aquarium's ecosystem. Excess ammonia, nitrate, and phosphates are eliminated with the help of the algae and corals growing on the live rock's surface ...
The processed ammonia is converted to nitrite, which is then processed to nitrate. Weekly water changes (25% of aquarium volume), while vacuuming debris from the bottom of the tank, can solve this problem of nitrate build-up, provided the tank is not overcrowded. Build-up of algae is largely related to light level and mineral imbalance.
Schematic representation of the flow of Nitrogen through a common aquarium. Ammonia poisoning is a common fish disease in new aquariums, especially when immediately stocked to full capacity. Ideally, the level of ammonia (NH 3) and ammonium compounds (i.e. those containing NH 4 +) in fish tanks should be zero.
On the downside, T-5 lighting is the most expensive type fluorescent lighting available. Many times it is much cheaper per watt, especially in the long run with the multiple T-5 bulbs being replaced, to use an equivalent metal halide light setup over a T-5 setup if such high light output is required.
Nitrate is the end-product of nitrification, and is the least toxic of the nitrogen compounds, with 96-hour exposure LC 50 values in freshwater in excess of 1,000 mg/L. [6] A biofilter provides a substrate for the bacterial community, which results in thick biofilm growing within the filter. [ 4 ]

Relationship of phosphate to nitrate uptake for photosynthesis in various regions of the ocean. Note that nitrate is more often limiting than phosphate. The Redfield ratio or Redfield stoichiometry is the consistent atomic ratio of carbon, nitrogen and phosphorus found in marine phytoplankton and throughout the deep oceans.
Another light source in reef aquariums is metal halide lighting. These high output lights closely recreate the shimmering effect of bright tropical sun over a patch of coral reef. Metal halide bulbs come in a variety of spectra from 5000k on up to 20,000k and allow for a variety of light-hungry corals to survive under them.
