Is that it? Is my tank cycled?

Hello-

New to fish keeping, so far we're having a good time with this. We were going to put a goldfish in a bowl and then found out how cruel that is, so we opted for a 3 gallon Eclipse tank and 4 danios. We set this up almost 2 weeks ago, adding biospira at set-up to get the cycling started.

As of today my readings are Ammonia=0, Nitrites=0, Nitrates= more than 0 but less than 5.

Last week we had a spike in the Nitrites to 1.0 and Nitrates to 10 at which point I got nervous about the Nitrite level and did a very small water change (2 pints) to keep the stress down. About 4 days later the Nitrites were gone and the Nitrates really low and that is how it's stayed. So is that it, are we cycled? That seemed too easy. I was prepared for much more of a struggle based on everything I've read.

Thank you for your advice!

Hi Andyandsue, welcome to fishkeeping and to the forum.

No two cycling tanks are the same as there are many factors involved. It is possible that your tank has cycled - judging from the fact that your nitrite readings spiked and disappeared and you now have a nitrate reading then I would say so.

Your nitrates do seem pretty low though - can I ask is the tank planted at all?

And what it the nitrate reading from the tapwater?

Katherine :)

Thank you for the quick reply and ooh, that is a good question! I just tested and the tap is 0, the water I have on standby in a jug just in case is 0, and the tank is still between 0-5.

I do have 1 small stem plant broken into 2 that Petco sold as an aquatic plant. Not sure of the variety. It looks similar to a dracena with a wider leaf. I know my tank is small, do you think that is the reason for the low Nitrates?

This went like a textbook cycling but I was worried that I made a mistake doing that small water change. I am waiting for some surprise disaster, like waking up to 4 dead danios and in turn, 2 crying children. : (

Thank you again. I really want to be successful at this. I can see us buying a larger tank in the future-We are truly enjoying our danios. It's quite an addictive hobby.

No probs, I hope everthing goes well for you both.

That fact that your ammonia and nitrite reading are zero is a good sign - just keep a close eye on the water parameters.

The problem with having such a small tank is that changes can happen more quickly, and if you have the means to upgrade soon you will find that the tank is easier to maintain.

You have chosen the correct fish to cycle the tank with, as zebra danios are amongst the most hardy of fish. Try to feed lightly at the moment, just until the tank is a bit more established.

Again, I wish you well - and please don't hesitate to ask questions, it's how we all learn.

I figured since the ammonia dropped, nitrites spiked, and nitrates became detectable all at the same time that it had cycled. I'm going to keep a close eye, testing each day just in case.

Honestly since the tank at only 3 gallons is so small, I was only hoping to put maybe one or two more danio and that's it!

If we upgrade some time in the near future, I will research what else to put with danios, which by the way we all just love. They are such fun fish!

ahh!! stop with the thought of danios right there. They need to be in groups of at least 5. IN a tank that size i would either suggest a trio or duo of male guppies or a betta.

EDIT: im sorry, did you already have 4 danios? If you already have 4 danios i wouldnt add anymore fish since danios grow to 2 inches, thats 8 inches of fish in a 3.5 gallon tank. Although it should be fine since danios are extremly hardy, i wouldnt add anymore fish

Yes that is correct, we have 4 danios in the 3 gallon so I don't want to push the amount of fish. Since the tank is new and just cycled, that is the other reason there are only danios. Hence all the danio talk! : )

I will consider others when we get a larget tank. Just trying to get through the first few months so I can understand what I'm doing...

You were right- Yesterday I removed the plant(s) & gave them a few shrimp to eat. I tested the water later last night and ammonia was 0 but nitrites were .25 and nitrate was still 0-5. I changed about 1/3 of the water and cleaned the filter a bit (I didn't have a replacement on hand, but I will from now on) and this morning we are back to normal but the nitrate reading is up closer to 5!

So the lesson learned is no live plants in a small aquarium! Thank you!

Why wouldn't you want live plants in the tank? While it might theoretically make it harder to detect cycling due to nitrate uptake I would think that the advantages to live plants would outweigh the inconvience.
