For the past 3 wks I have been overjoyed that I have had a zero nitrate reading and then today when I tested again with the same result, I started to wonder if maybe I should be worried. Is having zero nitrAtes bad? (The API test shows readings in my other tanks so I know the tests are working.)

50G planted tank w/malaysian wood set up for 1 yr
0 ammonia
0 nitrate
0 nitrite
7.4 PH
79F temp
Current fish list in my sig
Rena XP3 filtration

I'm not sure it'd be enough to eat all the nitrates, but the plants use the nitrates as food. I have vines growing out of my tank, and my nitrates never get over moderate. If your tank is heavily planted and / or a low bio load then I guess there's a possibility that you'd have 0 nitrates. If so, congratulations on the balanced bio-system!

Life-Glo2 bulbs 8hrs a day, no ferts or co2. Don't know if it is considered heavily planted so I will attach a pic I just took. Had been doing weekly 20% w/c but since zero nitrate reading I have not done one. API test is approx 4 months old and other tanks which are not planted continue to have consistant readings.

My fish like to eat those plants so I don't know how well they get rid of Nitrates, but that does look like a lot of plants, and not too many fish in there. I think that it might be possible that they are absorbing all your nitrates. I don't think it's your tester. You could test your tap water to see if there's any in there, and then do a 30% water change or so and test the tank. you could also ad ammonia, or just over feed the fish, and see if you get a nitrate spike. If you can get the nitrates to spike, keep testing the water to see if the plants eat up the nitrates. That's what I personally think is happening there.

Like your tank btw. Looks awesome!

Thanks moto_master! I was just making sure that having zero nitrAtes was really a good thing. I have always tried to maintain a low nitrAte reading (which is normally around 10ppm) but am just shocked that it is now better than I had been trying for.

Sure thing. I don't know why it wouldn't be a good thing to have 0 nitrates. I strive for it...

Depending on your type of test kit - mine is two bottles of liquid - if so be sure to shake them well or results are not accurate.

As soon as I got a zero reading I tested and retested and even set timers to make sure I shook the vial for the correct amount of time.
