Should I be worried about a .5 nitrite reading?
Forum rules
Read this before posting!!
Since this board has been up, we have found there are several questions that routinely get asked in order to help diagnose problems. If you can have that information to begin with in your post, we'll be able to help right away (if we can!) without having to wait for you to post the info we need.
1) Your water parameters - pH, Ammonia, Nitrite, Nitrates and salinity (if appropriate). This is by far the most important information you can provide! Do not answer this with "Fine" "Perfect" "ok", that tells us nothing. We need hard numbers.
2) Tank size and a list of ALL inhabitants. Include algae eaters, plecos, everything. We need to know what you have and how big the tank is.
3) Feeding, water change schedule and a list of all products you are using or have added to the tank (examples: Cycle, Amquel, salt, etc)
4) What changes you've made in the tank in the last week or so. Sometimes its the little things that make all the difference.
5) How long the aquarium has been set up, and how did you cycle it? If you don't know what cycling is read this: Fishless Cycling Article and familiarize yourself with all the information. Yes. All of it.
We want to help, and providing this information will go a LONG way to getting a diagnosis and hopeful cure that much faster.
While you wait for assistance:
One of the easiest and best ways to help your fish feel better is clean water! If you are already on a regular water change schedule (50% weekly is recommended) a good step to making your fish more comfortable while waiting for diagnosis/suggestions is to do a large water change immediately. Feel free to repeat daily or as often as you can, clean water is always a good thing! Use of Amquel or Prime as a dechlor may help with any ammonia or nitrite issues, and is highly recommended.
Note - if you do not normally do large water changes, doing a sudden, large water change could shock your fish by suddenly changing their established water chemistry. Clean water is still your first goal, so in this case, do several smaller (10%) water changes over the next day or two before starting any large ones.

So those filters from your friend will be coming off of established tanks with fish in there now?

Re: Should I be worried about a .5 nitrite reading?
I may have missed this but what kind of puffer is this? Definitely need to get some established filter media in there, PufferPunk is right your tank isn't cycled right now. I hate when LFS's give you the "it's fine" answer, makes you think the water is perfect. For them fine could be showing small amounts of ammonia and nitrite and that's ok to them. For puffers you really need to have no ammonia or nitrites, so their fine may be your terrible...

Yep, anything but zero is dangerous for puffers. Actually, it's dangerous for any fish, but it's super-dangerous for puffers and their delicate skin.

yes he has a tank that's been running forever!Pufferpunk wrote:So those filters from your friend will be coming off of established tanks with fish in there now?
Re: Should I be worried about a .5 nitrite reading?
Ok I'm really aggreeing that these strips are junk! the 0 nitrite reading is white on the paper guide that comes with it. When I did my test again this morning is a light light beige on the stick. but there is no light beige square on the paper at all! the .5 is light pink...I will note that my puffer is very active this morning. Swimming up and down the tank and being very interactive. I'm sure the water change made him feel much better. Wow you guys have helped out so much. I'd like to thank you again!

WC always make fish feel better, even in a healthy tank!

I'm really glad to hear that he's doing better.

Re: Should I be worried about a .5 nitrite reading?
Back from the pet shop, She checked my ammonia-0 nitrite-0 nitrate-0 I guess everything is fine now. She noted that my PH was high but I don't think I can lower it without hurting the fish..thanks again

Re: Should I be worried about a .5 nitrite reading?
Don't worry about pH. I keep my DPs in 8.2-8.4, even though they come from slightly acidic water, and they couldn't care less.
Get those liquid kits and keep an eye on the tank. The water changes eliminated the ammonia and nitrite, but that tank was empty for a week and was not fed an ammonia source, which starved your nitrifying bacteria. I don't think you're out of the woods yet.

If you are showing no nitrate, I'd be worried that the tank isn't cycled. An established biological bed will be releasing some nitrate.

Re: Should I be worried about a .5 nitrite reading?
With the strips I have had problems with false-positive tests before. So there is also the chance that your tank has been fine all along and the testing kit is to blame - all the more reason to get a proper one. I've had testing kits report nitrite/ammonia/nitrate in the water and got worried but when I test clean tap water and still get readings you know something is amiss and its time for a new kit, after I got the proper kit my readings were all normal.

Re: Should I be worried about a .5 nitrite reading?
+1 to this. I don't think you are over your troubles yet. The numbers you LFS gave you are indicative of a uncycled tank and by keeping fish in there you are heading right back to where you started. If you can get some Dr. Tims or some used filter media from a friend with a well established tank to do an instant cycle.Pufferpunk wrote:If you are showing no nitrate, I'd be worried that the tank isn't cycled.
