Hello, i have set up my 112 gallon aquarium and it has been set up for 6 days and i have tested water everyday and has come up 0 for ammonia nitrite, so on the sixth day i added some tiger barbs and still nothing changed is this suppose to happen and help would be good thank you

...sounds like everything is going according to plan! Congrats! Sounds like your tank has cycled - although 6 days isn't the norm...and you haven't added too many fish...

...your bacteria appear to be breaking down the ammonia from your fish which is why your reading is 0...

How many barbs did you add? Never mind...my dial-up is slow! I just read 3...

...now the trick is to keep up the good work!

Would my tank be able to cycle in just 6 days? I have squeezed my filter sponge from my other cycled aquarium and added a peice of driftwood that was already in an established tank, but would that help cycle the tank so fast?

Yes, it can. What is your nitrate reading?

...technically yes...as long as the new tank has the proper bacteria...it will cycle faster than if you were starting from scratch...

...I don't know how much bacteria you added by squeezing the sponge...but the driftwood will certainly have a covering of bactera...

I am not sure what my nitrate reading is because my test kit did not come with a nitrate tester so ill have to go get one to see. So if the ammonia levels or nitrite levels do not raise soon does that mean i can add more fish?

Cautiously you can add small numbers of new fish. I think what is going on is you have such a small number of fish and such a large tank that due to the fact that you seeded some old material into the tank the bacteria are able to keep up. Probably just barely though, if you went out and put a ton of fish in there a massive ammonia spike would ensue. It should be safe to start adding a few fish :)

I agree, be very careful until you are sure it has cycled, and even then add slowly or you can throw your tank into a mini-cycle which isn't fun to manage. (Been there, done that!)

One of my tanks cycled super fast (about 12 days) but I used BioSpira (which has its devoted followers and non-believers). If you haven't had a reading of any nitrites yet, I would be doubtful it went through a cycle. It's possible there isn't enough ammonia in the tank for it to read yet. I had that happen to me when I started my larger tank.

Definitely test the nitrates. Once they appear and the ammonia and nitrite consistently read 0, your tank is cycled.

I agree also that you need to be very watchful for ammonia spikes. The addition of the driftwood and ringing the sponge may have done no more than gave you enough bacteria to handle what little food you were adding and now is handling the very few fish you have added. When I first did a fishless cycle I didn't even see ammonia for 5 days then it was trace for 3-4 days. I didn't add enough food and this was only a 10 gallon tank.

You can stick with the fish and as long as you don't get any ammonia or nitrites then you can add slowly, maybe up to 5 more. The tank is huge for that many fish so your ammonia levels could be there but are unreadeable.

I have a 55 gal tank that I started about a month ago. I seeded mine like you did with the sponge filter from an established tank and haven't had much if any readings for amonia or nitrites but the nitrates started going really high after I added 3 zebra danios. I've been doing 30-50% water changes 2x a week for the past couple of weeks and am finally getting better nitrate readings....so I think you should be testing for nitrates even if the ammonia and nitites are testing good.

I may be wrong, but I was told on larger tanks the cycling process takes longer. On my small tanks when I start cycling the tank, before I add fish, I would dump fish food on the gravel and let it rot for a week before vac'ing it up...the decomposing fish food seems to aid in bacteria growth. I have also read that cycling can take longer than two weeks, in my small tanks I have noticed its more like 7-10 days for the spike then the decline. I always add fish VERY carefully, as too many will cause a nitrate spike again.

The big thing on the size of the tank for cycling is the amount of bioload that you put in it. If you put the same fish load in a smaller tank, it will be more noticable on the ammonia/nitrite/nitrate levels. That is why when you start your first tank, it's a bit safer to start with a larger tank and low levels of fish as there is more water to diffuse levels. Using the fishfood method, you will probably want to use more food to create a larger load. In the long run to fully build up the full bacteria levels, it wil ltake longer though for the larger tanks. It's possible to cycle a larger tank with fish and never notice ammonia/nitrite spikes.

I am a big fan of using lots of fish food and some Cycle(r) or other bacteria aiding products. combine that with some rocks or driftwood from a cycled tank and some of the filter material in the new filter, I am ussually able to cycle a 20ish gallon tank in a week.

as far as the fish food goes, dump alot of it in one corner of the tank...it will rot away and after a week use a gravel vac in that corner to clean it up.

be very carefull adding fish for a couple weeks...

It is good that there is no ammonia and nitRITE in your tank, but the true test will require you to purchase a nitRATE test. when bacteria in your tank eat the ammonia and nitrite, they turn it into nitrate. If you are getting some nitRATE in the tank, but no ammonia or nitRITE, they your tank is cycling correctly, and you can begin adding a few fish at a time.

Remember if you add too many fish all at once you could be adding ammonia and nitRITE faster than your bacteria can catch upa nd eat it and you could harm or kill your fish.
