Like a lady or a gentleman. Notice: you are the only one swearing or being rude.

I would also like to point out (again) that the paper you are claiming says the method of NO3 to NO2 reduction involves the liver is about invertebrates that do not have a liver.


I found no mention of liver/ hepatic system use in the first article either.

Here's your source. I hope you have a joyous and pleasant day. It is difficult to find primary literature that is available to the public and can therefore be legally linked to. The vast majority of the sources I found require a paid subscription, or alliance with a university to read. While I have that, I am going to presume that most readers on here do not.


This article shows lymphocyte production as being halved in high nitrate conditions.

maybe i overeacted a bit. If I offended you I sincerely apologize.
 
Apology accepted.

Nitrate poisoning in vertebrate animals is poorly understood at best. There are as many theories as their are people studying the topic.

I think it is safe to say that there are a few mechanisms responsible for poor health that results from exposure to elevated nitrates.

75ppm like trying to breath in a house fire. It's not good for the fish, but they can live a long long time with it. Who knows whether or not it actually decreases the life span.

How many months can we live breathing house fire smoke? Okay, okay, so your point is, fish CAN breathe in house fire smoke?! So, you were using an analogy that really isn't applicable to fish? huh?

why revive a thread with little redeeming value in which you weren't really a part of the discussion to begin with? Just to start stuff? That's really kind of petty and childish huh?

just let it go....

Its not the nitrates themselves that cause the problem. Nitrates greatly impede the production of white blood cell which over time renders the immune system useless. Once the immune system is shut down, its only a matter of time until some germ/parasite/ buggy gets in there and kills the defenseless fish.

Fish can survive a LONG time in nitrates of 200ppm...as long as they don't get exposed to ICH or something worse... they live on. Personally I would rather have my fish a little more capable of fending for themselves. Keep the nitrates under 20.

My nitrates have been 40ppm for years and I keep loaches. They've had ich only a couple of times (because of introduction of a loach with the disease). They survived all outbreaks and are thriving. I do 70percent water changes a week. It's really not a problem...

Also we need to be clear here. Some kits measure nitrate-nitrogen levels, mines measures ppm which is the actual number of IONS. If you use PPM you need to divide by 4.4 to get the level.

Also even though I have the master test kit, I know it's not very accurate at measuring, specifically nitrate. I'm sure my levels are lower than 40ppm. I'm doing utterly huge 70percent weekly changes and vacing hard, not overfeeding. Yes I am a little overstocked.
 
Howdy,

EPA drinking water guidelines allow up to 44 ppm nitrates (except wells). This might be as low as some members can get it by water changes.

I agree, in fact I'm just off to test my tap water right now, brb with the results.:grinno:
 
Just waiting the 5 minutes there for colour to develop.

Results after testing 5ml of my tap water it contains : 20 PPM. This was the colour closest matched. Id go as far as saying it was "almost" dark enough to coincide with the 40ppm...

This explains ALOT!
