Hi I have just set up a 22 gal tank had it running for 5 days went to get first hardy fish to start cycling but when I took a water sample to fish store said I couldn't do it yet as tank was already cycling.so I bought an api freshwater master test kit have done some tests and my ammonia reading was .25ppm nitrite .50ppm and nitrate was 40ppm how is this possible? So confused I do have a piece of wood in the tank that I got from the store could this be the cause? Plants and decs are all plastic any advice would be great thanks

Test the nitrates in your tap water.

Has anything in this tank been in another tank before?

Hi yes I tested my tap water no nitrates showed up.some of the decorations I have put in were from a 10 gal tank I had 2 years ago. But I did rinse them all thoroughly.

I'd retest the nitrates, really shake that second bottle hard for 30 seconds. This will be a control to make sure you aren't getting a false positive.

Have you treated the water with conditioner or anything else? Like Safestart?

I have used tetra aquasafe as my water conditioner that is all and left it running. Did u mean retest my tap water.? Because myself and the fish store have done my aquarium water and both showed the same

Have retested tank and tap water tap water still saying no nitrates and tank water is around the 40ppm I dont get how it can without a proper ammonia source but they all still showing same results confused .com!!

Could it be something decaying on the driftwood?

That is the only thing I can think that is doing it it has started to get a bit of white stuff growing on it. And it is the only real natural object in the tank so maybe that is the cause

Was the piece of drift wood from a tank or was it on a shelf? If from a tank it is very possible that it already had bacteria on it and helped to jump start this cycle.

Since you will be doing a fishless cycle you need to add ammonia to feed the bacteria. The fish do it during a fish in cycle but since you have none you will have to do their job.

You could use fish food but it has to decompose before making ammonia. Pure ammonia is a cleaner option and the amount of ammonia can be controlled better.

The drift wood was on the shelf at the store brought it home rinsed it and put it in tank when I set up. Fish store had said to wait til all my readings go back down then add few hardy fish with a bottle of colony! But I had been thinking about a fish less cycle just dont know anywhere local I can get the ammonia

Shouldn't have had bacteria on it then. You said you used some deco from a 10 gallon tank but if the tank hasn't been running for 2 years I would think all the bacteria on them would have died off but I guess it is in the realm of possibility that some survived.

I guess I don't really understand the info you got from the LFS. I can see the ammonia and nitrites going to zero but if they told you to wait until ALL the readings go back down maybe they didn't actually mean ALL since the nitrates will just keep building up until they are lowered with water changes.

Is it possible for you to order Dr Tim's ammonium chloride from amazon? Some folks use that. Others have found janitorial strength ammonia at places like Ace Hardware and even others have found some in their local grocery type store. What ever you get if you decide to take this route be sure it has nothing added to it to make it smell or clean better.

It has me confused to like u said! my fish store only tested nitrites and nitrates. I tested the ammonia and nitrites and nitrates when I bought my test kit and was showing ammonia reading as well as what I have mentioned may have to go back and ask them how the nitrates will be able to disappear without changing water. I will look into getting some ammonia thanks for the advice

Sadly sometimes some of these folks talk so confidently it seems they know what they are talking about but often it is nothing more than an act. It pays to question advice received from a lot of them. If they don't truly understand what is supposed to happen they tend to give bad advice and state it as fact.

They do only deal with fish and are quite reputable where I am from on the plus side least they didn't let me just buy fish to bring them home for them to die when my water isn't right yet. Just out of interest I have a cannister filter set up it has 2 trays came with ceramic rings 2 filter pads and a carbon filter i have them all in at the mo but would u replace the carbon filter and add more ceramic rings and possibly filter floss or another sponge?

They could be very trustworthy then but it never hurts to get second and even third opinions

I haven't used carbon in a very long time. If it were me I would use the space taken up with carbon for more bio-media. (sponges are good too) A bit of filter floss is a good idea too. With enough ceramic or other permanent media the floss can be replaced as often as needed without fear of throwing out bacteria.

I use poly-fil (yep, that same stuff made for stuffing pillows) and replace it each week. A big bag of it can be bought cheaply and a bag will last a long time even replacing it each week. It does a good job of polishing the water.

That's exciting. The first thing I would want to know is what is coming out of your tap. What kind of declorinator? Add anything else?

That was on 5th day of set up went to other store yesterday they said this is possible then gave me some bacteria in a bottle to add which I did. Have checked levels again tonight ammonia has nearly dropped completely nitrite has dropped very slightly and so has nitrate just have never heard of this without a proper ammonia source

I have tested my tap water as well there is no nitrate or nitrite. I used tetra aquasafe for dechlorinater
