Nitrifying bacteria and the breakdown of waste in the aquarium

Nitrifying bacteria aka the good or beneficial bacteria, are present after successfully . Nitrifying bacteria provide natural biological aquarium filtration and are responsible for breaking down organic waste within the fish tank. Transforming ammonia to nitrite, and nitrite to nitrates. Nitrifying bacteria settle on rocks, gravel, filter media, sand, bio-wheels, etc. Let’s take a closer look: Nitrifying bacteria […]

Where does aquarium nitrate come from?

There are various sources of aquarium nitrate, some can be avoided and some are inevitable. Remember, high nitrate concentrations in the fish tank are the primary cause of algae outbreaks and green aquarium water! Avoidable sources of aquarium nitrate Tap water contains nitrate This includes both city and well water. City water is normally regulated […]

How to remove nitrate from the aquarium

Nitrates are generally very low in natural waters, in part by the high rate of dilution due to large quantities of water, but also because of the hydrologic-cycle. A common practice used to lower aquarium nitrates is the . In reality however, water changes are more of a nitrate dilution then removal. How to remove […]

Cycling the aquarium without fish

An aquarium is considered safe for livestock once the nitrogen cycle has completed, and the natural biological filtration has been established and is working. The nitrogen cycle converts toxic ammonia to nitrate by oxidation through bacteria. These bacteria make the water safe for fish, a process that starts as soon as ammonia is present. The […]

Ammonia in the aquarium and its effects on fish life

Ammonia buildup results from a breakdown of fish metabolism. Since ammonia (NH3) constantly converts to ammonium (NH4+) and vice versa, ammonia test kits usually measure both, resulting in a total ammonia (ammonia-N) concentration. In an established tank, the reading of this test needs to show an undetectable level at all times. A detectable presence of […]
