nitrite

Hi, I am cycling my sump for my Betta rack system. I am using the API Freshwater Kit. I shake the living daylights out of all the bottles before use to avoid the crystallisation. I have cycled 5 tanks previous to this with the fish food method and had no issues whatsoever. This time I decided...

Afternoon all, Living in South East London, I've traditionally battled high nitrate levels in my tap water. Today though, I have a rather different issue. Having just filled a 200 litre bucket ready for tomorrow's water change on my 200 gallon, I dipped a test strip in. When testing my tanks I...

I had my water tested on Wednesday just went, ammonia was 0, nitrite was 0.25-0.5. Nitrate was 5. I performed a 30% water change on Wednesday then I have been adding ammonia and nitrite digesting bacteria every day since Wednesday and after testing today nitrate is 0, ammonia is 0 but nitrite is...

Hi everyone! After all the trouble I've been trough with my tank, when I finally thought it was all going to be okay for a while, this happened in my 120L tank and I've run out of ideas of what I can do to solve it. I had a read of 5 ppm (probably more) of ammonia so I instantly searched in the...

Hi all, been dealing with a nitrite spike for the last 7-10 days at 0.25ppm. Currently doing water changes everyday to try and get it down to 0 but it’s not really working atm (I’ve done another threat for that proborn). 😐 In the meantime I’ve been adding Aqua One Tropical Conditioning Salts in...

Help! My tank is cycled and has been running for over 6 weeks. All my levels have been great up until last week. My nitrite spiked at 1.0-2.0ppm. I did a 50% water change and it dropped to 0.25ppm straight away but has now been stuck at 0.25ppm for over a week. I have been doing 30-50% water...

Hello again, Tank size: 5 gallons Temperature: 78° F Filter: Regular carbon Heater: Yes Water changes: 10 to 25% weekly Treatments: Tetra SafeStart+ (initially), API Stress Coat+ (regularly) Tank mates: 4 (down to 2) guppies pH: Stable 6.6 Ammonia: Less than 0.25 ppm Nitrite: Somewhere between...

Hey everyone! I hope you’re well :) this is my first post so please be kind! I’ve been reading so much conflicting info about high nitrites and I’m super confused. Im extremely new to keeping fish and I want to get it right! I was told by my local fish shop to cycle my fish tank for 24 hours...

I have a planted 10 gallon tank that I have been trying to cycle for over a week now. At first I was adding beneficial bacteria to the tank, but then I got a hold of filter media from an established tank. Before I put the media in the filter, my ammonia was at about 2ppm from dosing a small...

Hey guys this is my second post and since I received so much help regarding my questions on my first post I want to, once again, come here and ask a question. So I have had my tank for over 3 weeks now with fish in it (was established prior to putting fish in through a fishless cycle with Fritz...

I'm looking for some kind of monitoring system that will meassure eg. pH, nitrate, nitrite, temperature, tds etc. I have a TDS meter, digital thermometers in each tank and different chemical test sets to test for nitrate, nitrite and pH. I'd really like some kind of monitor or electronic tester...

After a little help here, as I'm non-plussed. I'm mid-fishless cycle with a 450l (120 us gallon) tank and my nitrite readings are making no sense to me. I started with adding Dr Tim's ammonia a couple of weeks ago, plus "one and only" bacteria. I know there are mixed views on whether it does...

hey guys! new to the forum as i’ve completed gave up trying to figure out the issue myself, and my LFS is absolutely zero help. currently have over 600 gallons of tanks ranging from 3 125 gallon tanks, 2 75’s, 2 29 gallon, and a 40 breeder hospital tank all in my detached garage/fish room.. i...

So I'm trying to cycle my 29 gallons with fish in them, I bought pretty hardy fish but think I got too many in there for it to cycle well. I currently have 5 guppies, 1 platy, and a spotted catfish. I recently moved them from my ten-gallon tank so it has some of the substrate from it (that...

Hi all, I could do with some help with one of my platinum lyre tail mollies. We noticed today that he is sort of floating on the surface. I say sort of because he does swim around, albeit slowly. He has his mouth partially open, but doesn't open and close it. He also isn't eating. It almost...

Hi guys, I need help. So I have a 20 gallon heavily planted tank that’s been running for about 6 months. Until now everything was perfectly fine, nitrite 0, nitrates between 10-25. I can't test for ammonia because none of the pet stores around here have any kind of ammonia tests for some reason...

I checked the Amazon page for this product after seeing what looked like anomalous test results for a member cycling thier tank. The number of bad reviews complaining of inaccurate or plain ruined test strips here is very alarming to me, especially since a lot of the budget priced items tend to...

Hi there, I recently completed my first aquabid purchase--a gorgeous big fin koi half moon male that came from Thailand. I unboxed him Thursday evening, he wasn't dead but arrived with a good bit of his tail fin missing. I couldn't tell if it was fin rot or if he was tail nipping during...

Hi guys, Dunno what I’m doing wrong. Started my fishless cycle 2 weeks ago. Added enough Ammonia to get it to 3ppm. 13 days on the ammonia is still the same and Nitrites are low. What could it be and what can I do to remedy it? Tank is set at 28 degrees c. Thanks, Dan

My readings are Ammonia- 0.25 ppm Nitirite- 5 ppm Nitrate - 20 ppm Do I need to continue feeding ammonia? Does my tank need a water change? Any advice is appreciated, thank you

Hello everyone, i need some advice on fishless cycling.I'll give information about my tank before stating the problem. 46 gallon running a penguin 150 biowheel and a fluval c4 hob filter planted tap water readings 0/0/0 ammonia-old country (5 percent) Lots of seeding material So i'm in the...

I came home today to a bottom dwelling fish desperately hovering at the surface and breathing very deeply.  Apparently my filter had gotten clogged with java moss and was hardly running.  So, I immediately fixed that, and centered my filter so the oxygenation could be distributed more evenly.  I...

Hi all,   So basically, I've had my tank set up for nearly a year now, and It's been fine for a long time. Recently (about 2 months ago) I noticed that the Nitrate levels were increasing, I increased the number of water changes to twice a week. Now I didn't take a lot of water out the second...

Okay so I'm new to the fish keeping hobby. I have a 29 gallon, a 10 gallon & 5 gallon... go big or go home right? I've had the same problem with all of my tanks. Very high Nitrite and nothing I do seems to fix the problem. PH - 7.5 Amm - 0.25 Nitrite - 5.0ppm Nitrate - 20ppm Heaters in both & I...

Hello there!!!   Due to thievery of buckets and general busyness/laziness with perfectly maintained tanks... my tanks are no longer perfectly maintained and my water is crazy.  Now I have some questions.  For the stats, after the LFS telling me I had issues, I bought a test kit yesterday to test...

So I had a tank for about a month and 2 weeks ago I began testing the water. I saw that the nitrates were through the roof! So I had been doing water changes everyday of 20% and then eventually to 50%. After I saw no difference, I did an 80% and all the fish died, but anywho...   With a fishless...

So the nitrite levels are off the chain, and I did my research and found out that I have to do daily water changes until it goes back down. Then I found out each water change is supposed to drop it to zero, and if it doesn't, increase the amount of water change. Well after a week of doing 25%...

Hey, I've had a fish in a bowl for a year or so. Male betta, hardy little bastard. About a month ago I set up at 25gal tank and he's been doing pretty good with the cycle. I'm to the point where I'm waiting for the bacteria that breaks down nitrites to do its job, but its taking a bit longer...

So im at day 15 of cycling my 10 gal tank and i am excited that i am finally seeing nitrite because that just means that i am getting that much closer to being cycled and getting my endlers!!  This may seem silly but i'm just excited that i am one step closer!! 

This is an open thread to ask questions about cycling.

I have a 10gal tank that has been cycling with fish for ~4 weeks.  I have 0 ammonium and my pH is generally around 7, though today it was 7.5.  Not worried about that because I'm going brackish soon.  My nitrite has been high for over a week now, though.  It was .75 maybe 5-6 days ago.  Today he...

I just started my aquarium 2 weeks ago, I did some research but I am no expert and like many others, I learned by my mistakes! my LFS never told me about cycling so I lost 3 guppies and an albino pleco by day 10. Mind you I never changed the water, everything was brand new (no bacteria).. the...

today my new plants arrived and they have been placed in the tank ,    new tank 2 weeks old water chemistry baseline was as you would expect  tank is 100 litres in size  ( 1 us gallon = 3.7litres)    Ph = 7.2  Ammonia, NH3  = 0 toxic Ammonia NH4  = 0  nitrite NO2              0 Nitrate NO3  ...

Hi Everyone,   Quick question I need some help on.   My tank is 30 days old now and I did a fish-in cycle (not many fish). Ammonia has been zero for 1.5-2 weeks, nitrates have fallen to 0 in the last few days but nitrite continues to climb until I do a partial water change. Usually it gets to...

Hi all   For just over a year I have had my 90 litre tank. In the tank I have 11 danios (pearl & orange finned), 3 platies and 2 platy babies. Excluding the baby platies, I have always had this amount of fish and have not experienced an ammonia problem before. I am using an Eheim bio filter 160...

I'm in the process of doing a fish-less cycle.    Here is a quick timeline....   January 19th-20th: All items for our filter came in, cut holes in the glass, set up the filter, setup the tank, monitored for leaks and such since it was a DIY. Had a couple slow leaks here and there, and fixed...

After fishless cycling for over a month and adding a betta and japonica shrimp to my 28l tank after havig my water tested at maiden head aquatics.. Im having fluctuations. My ammonia is 0,05-0,1nitrates are 1-5 but nitrites are 0,2-0,4 This is really high right? Im using the jbl test kit...
