The Nitrogen Cycle and Fishless Cycling Techniques

In an aquarium or fish bowl the fish radiate waste, which over a brief timeframe separates into dangerous alkali. We as a whole realize that smelling salts is very perilous even in little amounts so as aquarists we have to find a way to battle it. In a little fish bowl that may mean making full 100% water changes each week yet imagine a scenario in which the tank were bigger like 10 gallons for sure on the off chance that it were a waterway like a lake or lake. How would we fight with smelling salts in a circumstance like that? Indeed, in nature nitrification happens. This is a characteristic procedure where advantageous microorganisms devour alkali and assistant makes water conditions ok for amphibian life. In our aquariums we have figured out how to support this microscopic organisms development and to screen it so we can reproduce a comparable environment alright for our fish.

The Old Way

The old method for doing this, and a few people still use it, is to set up your tank and include some dispensable fish that the aquarist couldn’t care less about. For the procedure to work, alkali levels first need to work to a level that is hazardous for fish. This is the reason modest minnows or guppies are utilized normally. In the event that the fish pass on during the procedure it’s no major budgetary misfortune to you.

Nowadays’ aquarists are changing their old ways. We currently realize how to reproduce the nitrogen cycle without utilizing any live creatures and can do it similarly as cheaply without trading off the wellbeing or life of a solitary fish.

How the procedure functions

The procedure starts with alkali working in the tank. Through the old technique, the fish would do their business in the water and that waste would breakdown getting to be smelling salts. Through the span of a few days and weeks the smelling salts levels would assemble. Living normally in the water, on the tank stylistic layout, the substrate and channel media are little nitrifying microscopic organisms called Nitrosomonas. These are the principal microscopic organisms we talk about in the nitrification procedure since they expend smelling salts straightforwardly. In their little numbers they start to devour the smelling salts as it assembles and insofar as there is sufficient alkali they will keep on repeating to expend it nearly as quick as it’s being made. In the initial couple of weeks the smelling salts is made rapidly and the quantities of Nitrosomonas are growing…growing…growing. In the end the microorganisms will make up for lost time to the smelling salts and will devour as quick as it’s being made. For the initial couple of weeks while you test your water you will see the smelling salts levels rising and in the long run arriving at the point where they spike and afterward start to fall as the microscopic organisms devour it.

These Nitrosomonas likewise emit a waste item. They oust nitrite. Furthermore, you may realize that nitrite is additionally a poison perilous to your fish, thought not exactly to such an extent so as alkali. As these Nitrosomonas replicate, nitrite levels start to ascend until they also arrive at a level dangerous for your fish. Luckily, nature has given a second sort of nitrifying microorganisms called Nitrospira. Nitrospira expend nitrite. So as the nitrite levels rise the Nitrospira microscopic organisms replicate so as to expend everything. This second sort of microbes likewise, similar to the primary, radiate a waste item called nitrate. Nitrate, not at all like nitrite and smelling salts is substantially less dangerous to angle and can work to a lot more elevated levels before it turns into an issue. The best way to expel nitrate is to perform halfway water changes. We more often than not do that by evacuating 20% every week and supplanting it with clean adapted faucet water.

The New Fishless Strategy

The Fishless Cycling Strategy works the very same route as the first cycling technique just no fish are utilized. Rather, we purchase unadulterated alkali or smelling salts weakened with water at our neighborhood supermarket and add it legitimately to the tank as opposed to including fish. There are really two kinds of smelling salts; there is alkali hydroxide, which is the thing that you purchase at the supermarket. It isn’t as extraordinary an alternative as alkali chloride since it can influence the pH a tad and it is additionally ordinarily weakened with water however we frequently don’t have the foggiest idea how much so the amount we include is experimentation. Alkali hydroxide, in any case, is promptly accessible and I have utilized it commonly. Despite the fact that it’s not the principal decision, it functions admirably and simple to discover.

What You’ll Have to Begin:

  • Tank
  • Channel and Channel Media
  • Substrate
  • Unadulterated Smelling salts
  • Eye Dropper
  • Salicylate Smelling salts Test Unit
  • Nitrite Test Pack
  • Nitrate Test Unit
  • PH Test Pack
  • Water Conditioner
  • Pen and Paper


  • Channel media or rock from a built up tank.
  • Air-stone (for aquariums with minimal surface unsettling)
  • Pneumatic machine
  • Turn around stream Valve
  • Tubing

Part I: Tank Set-up

  1. Flush the substrate and add it to your unfilled tank. This substrate will house a great part of the helpful microscopic organisms that will live in your tank. A more unpleasant substrate like sand or rock will be a superior home to microorganisms at that point smooth huge shakes or marbles.
  2. Fill your tank with room temperature faucet water. Include your water conditioner.
  3. Associate your channel. There are a wide range of sorts of channels available and the sort you pick relies upon the tank size, bioload (or measure of fish waste) and individual inclination. HOB (Hold tight Back) channels that accompany a bio-wheel are decent on the grounds that the wheel gives extra surface region to advantageous microscopic organisms to stick. The channel media itself will house most of all the helpful microscopic organisms in your tank. You would prefer not to cycle a tank without a channel nor would you like to keep a channel in an aquarium that you don’t expect to cycle. (for example 100% water changes rather) Doing so will constrain your tank to unendingly cycle presenting your fish to poisons more than once.

In the event that you plan on utilizing channel media from a built up tank, include it as of now. The microbes you will culture is as of now present in your tank so seeding isn’t required. Including the set up channel media, be that as it may, may significantly diminish the all out time expected to completely cycle your tank.

  1. Measure out the measure of tubing you will requirement for the air-stone to reach from the base of your tank to the pneumatic machine. Interfacing the invert stream valve will guarantee that your siphon won’t inadvertently start siphoning water out of your tank in case of a power blackout. This valve is exceptionally economical and can be found close to the air stones in most fish stores. Connect the air-stone and spot it in your tank. HOB channels give a considerable lot of surface tumult, which oxygenates the water. An air stone and siphon are redundant with a HOB channel but rather some different kinds that don’t oxygenate well may require the air stone.
  2. Since your tank is good to go up it’s a smart thought to run the gambit of tests to perceive what your water parameters are crisp out of the tap with no added substances. Record these outcomes. You may discover there is as of now a few smelling salts present. It is very regular to discover up to 0.5 ppm or more noteworthy in your faucet water.

Part II: Cycling

  1. When cycling with fish it is simply the fish that discharge smelling salts which is devoured by the microscopic organisms, however since we are cycling without fish it’s dependent upon us to give enough alkali to support and energize development of the microbes. Smelling salts can be obtained from a market or tool shop. Make certain to watch that the fixings are exclusively smelling salts hydroxide and water. Make certain there are no cleansers or counterfeit hues added to the container. On the off chance that you are uncertain, shake the jug tenderly. Suds will show up if cleansers are available.
  2. The power of smelling salts hydroxide relies upon the brand you purchase and there is no careful amount to add to your tank water. Sadly, experimentation is the best way to decide the amount to include. Start by including around 3 – 5 drops for every gallon of water, enable it to blend for a couple of minutes and after that test your alkali levels with your salicylate smelling salts test unit. You will at last need to add enough smelling salts to rise to the potential bioload. For most straightforward tank set ups, an alkali level of about 2.0 ppm will get the job done. In the wake of testing your water, add enough smelling salts to bring it up to the 2.0 ppm level. On the off chance that it goes a little over that is alright. Retest your smelling salts level and record your outcomes.
  3. Every day, add enough smelling salts to keep the level at about 2.0 ppm. Test your tank for smelling salts, nitrite and nitrate every day. Record your outcomes after each test. Check your pH frequently too. Any unexpected drop or ascend in pH can make your gainful microorganisms vanish and moderate or end your advancement. Throughout the following 1 – 2 weeks the advantageous microbes that devour alkali will start to separate the smelling salts you have been adding and will keep on duplicating to fulfill the need. Those microscopic organisms radiate nitrite as a side-effect. When nitrite starts appearing on your tests you will realize the cycle is well under way.
  4. At the point your tests show nitrite levels starting to raise you can cut the measure of alkali you include every day significantly. As alkali devouring microscopic organisms duplicate, you will see the smelling salts levels drop and nitrite levels rise. The second kind of gainful microscopic organisms that lives in your tank will devour unsafe nitrite and after that themselves, emit less destructive nitrate as a side-effect.
  5. Due to this second kind of microscopic organisms, you will at that point see the nitrite levels drop and the nitrate levels start to rise. This normally happens around weeks 3 – 4.
  6. When the smelling salts levels fall back to zero, the nitrite levels fall back to zero and the nitrate levels are appearing on your tests, at that point and at exactly that point, is your tank totally cycled. Congrats!
  7. Now you will need to do a fractional water change to keep nitrates at a sheltered level. Typically around 10 – 20 ppm is fine. After this water change treat your water with a conditioner that kills chlorine, chloramines and overwhelming metals and adjust your fish. In the event that you don’t have fish to include immediately, make certain to continue adding smelling salts every day to prop the cycle up until you are prepared.
  8. To keep up
