Cannot get nitrite down what do I do, help!

WEEK 5: Ammonia at 0
Nitrite: 5+ ppm
Nitrate:40 ppm
Been changing water, using primed even tried nitro sorb abs that doesn’t make anything budge. This nitrite spike WILL NOT END. I am going on vaca tomorrow and won’t be around for a week. WHAT DO I DO?????????
I have never experienced such a long nitrite spike 4-5 WEEKS!

Mine was a bit long too, really the best thing to do is wait it out from what I can gather. A vacation might actually be what you need assuming this is a fishless cycle.

Alright, what is it stocked with? Depending on what's in there, some things might have higher bioloads, thus producing more ammonia, thus making more nitrite.

Do you use any aeration in your tank?

The nitrogen cycle needs oxigen. The cycle can be reversed in an anaerobic cluster.

Just a filter, but that provides plenty of bubbles.

So far everyone says a different things, guessing around cluelessly. Not one person can give me a straight answer on something g as simple as a FISH CYCLE SMH.

You change 50% of your water now, and another 50% tonight, and 50% more tomorrow am before you leave. Salt the tank (1tbsp/gal) before you leave and hope not being fed, and the salt keep your fish safe while you are gone.

If it was simple, you wouldn't be asking. :p

Do as LowConductivity says and then do small daily water changes when you return to keep the nitrates lower.

When you clean your tank/do water changes do you also siphon the substrate? Or move the decor around a lot?
Could be the tank is cycled but the amount of waste your fish are producing and food that's not being eaten is causing the nitrates to be high. I'm not sure what you have in your tank, but different species/sizes of fish produce different amounts of waste and that could be the cause of it.

You could test your water source/tap water and see if that's it, but I doubt it would be that.

Do the water changes lower the nitrites at all? A 4 or 5 week off the chart nitrite spike is unusual. The only other time I have seen it happen was to a young lady I was helping a couple of years ago. 100% water changes would get them down but within a few hours they spiked back up off the chart. We worked on the issue for a couple of weeks. She was doing everything right but couldn't stop the nitrites rising.

We finally determined it was the aquarium decor she had in her tank causing it. Once the 2 pieces were removed the nitrites were gone. Although both pieces were supposed to be tank safe apparently they were leaching something into the water and causing what she was experiencing. Another young lady was seeing her ammonia spiking when it shouldn't have been happening. Again removing the decor solved the issue. Is something like that possible here?

Water changes drop the nitrites but they go right back up overnight. My ammonia has been zero this entire time. I have a large aquarium piece from petco so idk.

How difficult would it be to take the piece out of there? I don't know that it is causing what is happening but the only way we are going to know is to remove it. The other decor pieces were sold as made for an aquarium but for some reason they caused problems. I have to think some of the folks that make these pieces don't pay close enough attention to what they make them with.

I can try that. I’ll do a 40 water change and remove the piece and see if it goes back up in the morning. I’ll update you tomorrow. Thx

First step of nitrification is working: you have zero ammonia in your water and nitrite ist rising. The first step is done by nitrosomas bacteria.

Second step is not working. This should be done by nitrobacter bacteria. Nitrobacter has an optimal growth on a ph between 7 and 8. Although not toxic, a nitrate level of 40mg/l may be a bit high.

Oxigen level seems ok.

Whats your PH? lower than 6? This might inhibit fast growth of nitrobacter.

Do you have living plants in your tank? They will eat ammonia, nitrite and nitrate, preferring ammonia and nitrite. Elodea will do wonder. Even duckweed will help.

Do you use additives that prevent algae or bacteria bloom? Stop using it. Algae might be your friend. It works like a plant.

To many waterchanges might be part of the problem. A WC disturbes bacteria growth and adds additives with the tap water.

All that is only a good guess. Analysing water is test, smell, feel and taste.

This is where we’re at. It’s not as high as it usually is, but it still went right back up. I’ll do another water change today and tonight.

A little background please. I just read back and see you have fish in this tank. How often have you been doing water changes since this spike started? Had they been done daily this spike may have ended but I can't guarantee it would have happened. Each tank is different so what works for one won't necessarily work the same in another. That is my normal advice though.

Since the nitrites still went up with the piece removed we can probably rule it out as the cause of what is happening. To be perfectly honest I do have to wonder. If your nitrites have been this high for 4 or 5 weeks and your fish don't seem to be affected I have to wonder if your nitrite test is telling you the truth. Do you have any other way of getting them tested? As I am sure you are aware, it is highly unusual for the nitrite spike to last this long.

I do water changes frequently about once every couple days. And at a point every day for a week. I use prime, and salt as well. My tests are definitely accurate ( I use API MTK) a smaller cycled tank I had reads bright blue for nitrites but this one totally not. This aquarium stuff sucks. Why do I have to be the only one with some weird problem. All the money and time I put into this down the drain. I’m flushing my fish and draining my tank.

Add to your filter seachem purigen that product will absorb organic waste and will reduce your Nitrates with 24h mate

You really aren't the only one experiencing strange happenings. I know it may seem like you are alone but that isn't the case. Spend some time reading some of the other threads and you will see just how many folks are having issues needing to be solved. most are willing to do whatever it takes and don't threaten to flush the fish.

If you are seriously thinking of flushing live fish than I am sorry for the fish. :(

The thing is, not everyone is enjoying a quick easy cycle. If they were I wouldn't be trying to help so many folks figure out why their tank isn't cycling.

I have been reading some very good reports from folks that use Fritz-Zyme Turbo Start 700 bottled bacteria. It is one that has to be kept refrigerated so I would be concerned about ordering it online unless it is shipped in a box with ice packs. If you could find it at your local fish store it may very well get you over this hump.

O.k.
That is a lot of fish for a new tank.

The Bacopa plant on the right is a good start. To suck up Nitrate/Nitrite you need three to four times more of that type of plant (hope that's not only a plastik part). It's fast growing.

Your filter has only a small volume of filter materials. Nitrobacter will grow on every surface, so more plants and more filter materials like sponges will multiply your surface and help to keep up with your bioload.

This is a way to balance your bioload and get to a point where WC is needed less often. Up to then do the following:

1. Get plants.
2. Feed minimal every other day No more than completely eaten up in one minute.
3. Do 25% Waterchange. At first every day.
4. Do not add more fish.

Or do you have anyone from your frends what can give to you any cycled filter media. This will help also.

You may very well be underfiltered. That can cause what you are experiencing. Unfortunately the folks that make these filters highly over rate their effectiveness. I recommend using a filter that is rated for a tank at least twice as big as the tank we are running them on and even then sometimes it isn't enough.

Put the piece of decor back in there. By the looks of this tank there aren't many surfaces for the bacteria to grow on. Upgrading the filtration will help. You can either just upgrade your filter or go ahead and add another one. That is what I would do. You can never have too much filtration. I run at least 2 filters on all my tanks.

If you are concerned about too much filtration think about this. Right now I am running a filter rated for a 55 gallon tank on a 5.5 gallon tank. It is a penn-plax cascade 300. I can turn the flow down as needed for this size tank. The original filter crashed. I happened to have this one so decided to use it. It is working perfectly.

This should help. Moving more water will be pulling more water through the filters. Doing so should help feed the bacteria. I don't know how quickly it will start lowering the nitrites but I have no doubt that it will help. By having the one filter situated on one end of the tank it isn't moving much water from the far end of the tank.

I would move the original filter a few inches away from the corner. I would situate the new filter in about the same place on the other end of the tank. By doing this you should get plenty of water being pulled through the filters.
