    cycling the tank

    in New to the Marine Aquaria Hobby

    Posted

    ok since this is a genuine question:

    Cycling the tank.

    When you start up a new tank, your tank do not have all the benificial bacterial.

    Cycling basically means getting the tank to reach the equilibrium of having sufficent bacterial to break down ammonia (bad) -> nitrite (bad)-> nitrate (not so bad) as fast as they are produced.

    When you introduce the 1st fish (or some ppl use market prawn) in the tank, it will produce waste and ammonia will build up in the tank due to the lack of the 1st stage bacterial. Over days, the bacterial will slowly build up and ammonia concentration will decline but nitrite will start to increase. When the 1st stage bacterial are fully established, ammonia will be processed as fast as the fishes are producing it.

    At this stage nitrite will start to peak. Nitrite is also very toxic to the fishes. Again we have to wait for another batch of bacterials to grow in population to bring nitrite level down. When this bacterials are sufficient in numbers, the nitrate will boom so slowly nitrite will be undetectable.

    when nitrite is eliminated, the tank is cycled. equilibrium is reached. This takes approximately 4 weeks.

    The resultant nitrate is not as harmful to fishes. Large concentration of it does harm the fish well being and they might be more susceptible to disease. Reqular water change will help keep the nitrate level in check. Growing Mangrooves, installing denitrators, having deep sand bed will help too to keep nitrate level within acceptable levels.

    Now when you add new fishes, the balance is offset again. more fishes = more waste = need time to let the bacterial grow again.

    So even after tank is cycled, it depends how many fishes you add at one time. If you add several at one time and several again a week later, the bacterial will not be able to populate and break down the ammonia and nitrite in time and fishes die. That is why ppl say go slow, go slow :)

    Give the bacterial time to be established in your tank. Each time the equilibrium is offsetted (whether by introduction of new fishes/corals, increase in feeding frequency or quantity, dead fish/ corals unremoved) you need to give time to tank to balance the ecology system.

    hope this help.

    thanks for the help i really appreciate you spending so much time typing such a long thing and instead of using market prawns can you use a couple of dead fish?

    Yes and ends with 'p', that's one of them hahahaha!

    Haha bro, I actually spend much more time on bo liao websites than I would care to admit (mostly for work/hobby related research). I've come across all sorts of people with different motivations. Mostly, posts like that are for attention, or to use the second nick to boost the profile of the primary nick. The scary ones are the type who post because they lack attention in real life.

    hi, this has nothing to do with me because i bring my laptop to school everyday and i dun keep track who uses my computer and i seriously thought he was serious and if you want to think i had something do do with it... so be it
