    Looks like you've added many different bacteria solutions.. i guess the tank currently has a full list of bacteria populations at work.

    Your tank will eventually cycle on its own anyways, could be in the next week or even the next few days, so just need to have patience.

    I've been using bt9 for all my previous tank but this has been the most problematic. It seems like it's nvr going to cycle

    Re: tank cycling problem

    Hi guys I just saw an article saying that in acidic conditions ammonia and nitrite is not poisonous to aquatic life. The article states that as long as you use active soil your shrimps can be added within a week. They tested with ebigold soil, ada amazonia and ada malaya. All their shrimps are doing well and breeding

    Re: tank cycling problem

    Its possible... people have cycled tanks with fishes and shrimps put in from the start and some have zero deaths while others had all livestock wiped out.

    The variations in success rates are usually due to the levels of fluctuating conditions in different tanks, the pH can change (ie. via water changes, water quality or natural buffers) and the toxic levels of ammonia and nitrite levels can shift (ie. bio-load, filter efficiency, maintanence etc)... there is just alot less safety margin during the cycling period.

    I guess it just depends on whether you can keep the pH stable and toxic parameters under control... and whether you are willing to risk the livestock (ie. maybe use hardy "commando" fishes and shimps to cycle and test first, before introducting the more valuable/sensitive livestock).

    What kind of shrimps should be used as commando shrimps?

    The cheap kind... culled low-grade cherry or malayan shrimps from bulk bags, numerous in quantity and "dispensable".

    Re: tank cycling problem

    You could just leave them in the tank since they wouldn't cross breed with CRS... or just shift them to another tank to use as algae management crew.

    I have a small army of 60+ culled low-grade cherry shrimps which i shift around my tanks whenever i need to boost algae crew (and especially when i start up new tanks), they are the most useful and hardiest bunch of shrimps i've kept so far.

    Re: tank cycling problem

    Hi guys I don't know if this is good news or bad new, I tested the water today and the readings were 1ppm ammonia 0 nitrite 10ppm nitrate. The ammonia decrease might be because of the water change I did yesterday, I'm not sure where the nitrate is coming from as there is no nitrite present. Could it be from the tap water?

    Re: tank cycling problem

    Thats a good indication that your tank cycle is in progress.

    Nitrites at zero readings throughout the cycling period is quite common... its because the ammonia-nitrite converting bacteria and the nitrite-nitrate converting bacteria are different species.

    Very often the nitrite-nitrate bacteria process the nitrites faster than the ammonia-nitrite bacteria can produce, so you'll tend to see nitrite staying at zero, while ammonia steadily decrease and nitrates steadily increase.

    Re: tank cycling problem

    Hmm or could it be that our tap water has nitrates? ?

    Its possible... i guess you could just do a quick nitrate test on your tap water and see if any readings show up.

    Okay I'll do it now and post whether it is the tap water or not

    Re: tank cycling problem

    Really disappointing to say that yes the nitrates is indeed from the tap water which means my tank has yet to even begin the cycling process after 6 weeks

    Re: tank cycling problem

    I know this is quite an old thread but yesterday I just did a 30% water change and today I checked my ammonia level is at 0.25 ppm and nitrates around 10. I really do not know why my cycle is taking so long

    borneo wild plant soil releases very little or no ammonia if i am not wrong. therefore, for fishless cycling, it might take some time. add some cheapo guppies and leave the tank alone for 1 week. don't do wc at all. i am sure your tank will cycle.

    Re: tank cycling problem

    One or two months is too short to season a new tank. A tank water column can take many months to attain a stable and mature state.

    From my experience, the problem with new hobbyists is that they are very enthusiastic for things to happen. Bacterial colony growth and sustenance takes time. Hobbyists usually try to accelerate things by adding this and that after measuring this and that.
    My late old uncle never had any modern scientific knowledge at all, yet he had been keeping fish happily in his backyard for decades.

    Re: tank cycling problem

    Does that mean I have to look at an empty tank so a few more months?

    I noticed in your previous posts that you have started up and cycled other tanks for shrimps before? If your previous tanks were using shrimp soil, then that probably explains their much faster "cycling" period, because those type of soil don't release much ammonia (very often only trace amounts or even none), so the cycle could be completed alot faster with a much smaller bacteria population (less ammonia to process = less bacteria population required), especially with all the additional special shrimp bacteria solutions/powders being dosed.

    Btw, if you still have your other cycled and established shrimp tanks around, maybe try shifting some seasoned bio-media over to the new cycling tank, that will be more efficient in "seeding" the new tank with actual live beneficial bacteria.

    Re: tank cycling problem

    I do have other tanks around but I don't think I'll be able open up my current filter as it'll be a mess having to prime it again, can I just put it directly on the soil?
