Thread: 0 Nitrates

  1. Default 0 Nitrates

    0 Not allowed!
    Hey guys, I've seen everyone saying that 0 Nitrates is a sign of a uncycled tank...

    My current params are

    0 Ammonia
    0 Nitrite
    0 Nitrate
    7.6 Ph

    The tank has been stocked for over 3 months, 1 of 4 filters replaced (saved biomax that I had used in place of carbon)

    The tank is planted (i'd say medium, its no forest, but as you see in my sig I have a lot of plants)

    So do I have a problem, or is 0 nitrates possible...

    *note I haven't done a water change in around 10 days (just seeing if I could get a reading), I have only topped off the tank occasionally from evap

    Best way for me to answer your question is to give you a example as the answer can depend on a lot of different things.

    I'll use my tank as a example. I fishless cycled it a few years ago and watched it go through all the stages including some nitrates. I have moderately stocked tank with a fare amount of low demanding plants. I always stay on top of my filter maintenance and I don't over feed the fish. I change well over 50% of the water each week (closer to 80% I would think), vac the gravel, but I do not dose with ferts at all. Our tap water is very good with no ammonia or nitrates in it (based on a City Water Treatment report). I use the API nitrate test kit. Each time I test I get 0ppm of nitrates. The API test kit only starts to detect nitrates at once they get to 5ppm, as do a lot of other test kits. I know there would be nitrates in the water, just not enough of them to register on the test kit.
    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    The only possibilities are that your plants are using up all the nitrates (which is very possible if they are growing well) or the test kit is either expired or you are not shaking the regents enough. You really have to shake the snot out of the nitrate reagents.

    Yea, I have noticed a lot of growth from all of the plants, hey, I'm not complaining... but I always see people say that its a bad thing and wanted to make sure I am not the only one.

    The kit is good till like 2017, and I give em a good shake

    I think the <5ppm idea may be what i have going on

    My params also read 0,0,0. In my world, that's exceptional water quality!

    I dose nitrates into my tank even though I don't do water changes.

    I still plan to do PWC, probably 30% around once a week, I just have been told by a few people if I had an issue that the tank wasn't cycled lol.

    I've heard the hygro is a nitrate hog, and it seems to be growing well, so thats a plus

    I'm glad you are still planning on doing waterchanges. There are more things that build up in the water besides those we test for. People who think they do not need to do waterchanges are just fooling themselves and will end up paying the price eventually.

    two things...
    1. I probably wont vac the gravel but at least change water
    2. Why did it take me this long to see you were from WNY...???? I'm an admin on a local facebook page for buy/sell/ and trade fish..

    Agreed with the majority. Sounds like your plants are just soaking up the nitrates. I have the same issue with my 10gal planted Betta tank (or had). Floating plants, like Frog Bit, will eat it up. Anything that grows quickly should.
