nitrogen cycle in freshwater aquariums

I want to learn more about the nitrogen cycle and how to keep good water. Particlary what can cause nitrate spikes in established tanks. What waterconditions are best for good bacteria... thanks for anything that you know

Have a look here and it will explain the cycle.

Nitrates are the end product of the cycle, they can be the result of overfeeding, bad maintenance.

I am moving this post as well to the correct section as you posted it in the cichlid section,

10g Fry / Hospital / QT tank (as needed)

75g Saltwater Reef, Ocellaris Clownfish, Lyretail Antias (baby), Lemon damsel, Longtail Fairy Wrasse, purple dottyback, snails, crabs and a few LPS corals.

220g Still sitting empty (come on Lottery I need the numbers to come up!)

In planted tank the plants (even algae) will consume ammonia over nitrate.

So should something go bump in the night, the plants will consume the resultant ammonia and there can be a nitrate spike.

so an occasional nitrate spike could be a sign the tank is "healing" itself from some kinda shock.

maintain Fw and marine system with a strong emphasis on balanced, stabilized system that as much as possible are self substaning.

have maintained FW systems for up to 9 years with descendants from original fish and marine aquariums for up to 8 years.

With no water changes, untreated tap water, inexpensive lighting by first starting the tank with live plants (FW) or macro algae( marine)

In my limited experience, the main reason for a nitrate spike is due to overfeeding, the death of animal or plant-life, or not keeping up on water changes. Basically anything that is increasing the waste in an established tank will cause the nitrates to rise, and the best way to bring them down is to keep on top of the water changes and vacuuming out old waste. Plants will also help to keep the nitrates under control in a tank, particularly noticeable in tanks that are heavily stocked, or stocked with fish that carry a high bioload, like goldfish, livebearers, and some plecs. . .

I'm not sure what water conditions are best for bacteria, but my understanding is that they colonize on the surfaces inside of the tank and in the filter, so when you're cleaning your tank ornaments, or the filter pads, be sure to do so in old tank water, as the chlorine in new, untreated tap water will kill off the bacterial colonies, and can put your tank into a new cycling situation. Some people change out their filter pads monthly, but the advice I see most often is to re-use that old media for as long as you are able, rinsing as needed in old tank water and replacing it when it's clean.

Hope that helps?
