Panda Cory tank

So...as you know I upgraded my guys to a 12 gallon Eclipse tank. Really like it! But I do have a question though...Since then,I have been testing their tank several times a week. For the past month,nothing going on in there..literally..I test ammonia and keeps coming out 0. N'rate and N'rite are both O. So I am not sure where in its re-cycle it is...Or did it instantly cycle?? Thatd be sweet. But I wouldve thought with 7 (maybe 8 )corys,theyd create some trace of ammonia...I know any is bad...just confused...LOL

I recall with my 10 (but with a betta) ammonia showed up fairly quick...maybe with a 12 takes even longer?? Or is just that my pandas dont create much ammonia at all? So baffled...ready to put in a female betta and let it do its magic haha...if they get along that is of course.

Did you transfer the filter or some filter media from your old tank? Also, quite a number of the beneficial bacteria thrive in the substrate, so if you transferred it to the new tank, then you might have skipped a re-cycle altogether.
But if you didn't, then I'll be baffled as well.

Just keep on testing for ammonia, just in case the ammonia spike shows up a bit late for some reason.

Your fish love watching you as much as you love watching them. So please practice responsible fishkeeping.

Following up on adiumroot, how did you set this tank up? If you managed to seed the tank with bacteria, either by transferring (unwashed) gravel and filter media, plants, rocks, wood from an established (cycled) tank or with a biological supplement, then yes, the tank probably cycled the first day. Live plants would also have the benefit of using the ammonia from the start.

On the other hand, if everything was brand new and no biological supplement or live plants put in...you may have a problem looming. Or your test kits may be inaccurate?

Info on how you set this tank up would help us.

Thanks for the replies! Everything was transferred over from the 9 gallon the corys were in(sand and plants). I cut up the sponge that was in the old filter and set it in the new filter tray. Their 9 gallon was cycled.

Sure hope my test kit isnt bad lol. I do have a new set of them,maybe I will try that one just to be safe.

Thanks, this is good. In this case I would expect nothing bad. If sufficient bacteria is put in a new tank when the first fish go in, and by sufficient I mean sufficient to handle the ammonia from those fish, then you will have zero ammonia and nitrite from day one. I've set up several tanks over the years, this is always what occurs in mine. Also the plants consume ammonia/ammonium from day one as well. I wouldn't distrust your test kit in this situation, from what you've told us I think you're tank is fine.

Oh,cool. Well good then. I remember it took forever to cycle them in the first place,so I am glad it instantly cycled from the get go. Of course I will still test their water every so often to be safe.

I think your tank is fine since you transferred some media from your old tank.
Sterile tanks can be seeded with bacteria by just throwing a SMALLl piece of raw shrimp or dead minnow in the tank and letting it rot. It jump starts the nitrogen cycle. It will cause a spike in ammonia and nitrite and then when the ammonia and nitrite get down to zero it's safe to add fish.

This is very true, it's referred to as fishless cycling. The problem (sort of) is that it can take anywhere from 2 to 8 weeks for the tank to fully cycle. I won't repeat what I've written elsewhere about how this works. The advantage of being able to "seed" the tank is that it cycles the first day when the first fish are added, provided as mentioned previously that the bacteria is sufficient for the number of fish. And having live plants really assures success provided the fish are not beyond the capacity of the plants and bacteria.

I see. Like what Byron said, no reason to doubt the test kit now.

I hope your cories enjoy the new home!

Your fish love watching you as much as you love watching them. So please practice responsible fishkeeping.

This is what i have been doing for a few years and it has allowed me to cycle any tank in a few days.............I use alot of filter floss in my canister filters and when i clean and change the filter floss, i take the old floss and rinse in old tank water and then put it in a piece of pantyhose and tie it off..Place the pantyhose/floss in my largest tank (or tank with the largest bio-load) and let it sit.......This piece is already seeded with bacteria and is waiting to be used in a new tank............Both my shrimp breeder tanks were cycled in no time doing it this way and i never lost one shrimp.......I have found this to be an instant solution for jump starting a tank's cycle...........
