Help! Nitrates with no Nitrites?

Chomas007

Hi guys... It's me again... asking for more help regarding my chemistry homework (aka nitrogen cycle) lol.
Anyway, Its almost been a week of cycling the tank and yes, I understand I am nowhere near close to finishing the cycle but heres the situation. I have 1ppm ammonia present in the tank right now with no nitrites but 5 ppm nitrate? Correct me if I am wrong but... you can't have nitrate without nitrite right? Here are the pictures. The one with nitrites present was two days ago and the one without was taken today.

It wasn’t letting me post the second picture… here it is.

You only get nitrates from nitrite. Ideally you would have 0 nitrite because it all converted into nitrate.

So to answer your question: yes, technically you can have nitrate without nitrite....because that's what you want.

When was the last time you dosed ammonia and what is your ammonia source?

the last time I dosed ammonia was maybe last thursday or wednesday? definitely not in the last 2-3 days though. the source was Dr. Tim's Ammonium chloride. However, yesterday I added in new plants into the aquarium. one pot of anubias nana the small one and one pogostemon helferi. and two seachem root tabs.

the tank has stayed at a constant 1 ppm ammonia since friday.

Hrmmm....I would hold off on the root tabs for now. They contain nitrogen and phosphorus and you already have enough nutrients in the water via ammonia and nitrate. The extra fertilizer can lead to rapid algae growth.

Without the root tabs in there what you will see is a reduction in ammonia and nitrate because the plants are eating it up. The plants will actually help your cycle.

Leave everything as is for now and check your levels again in 24 hours. Give the plants some time to do what they do. After things level out we can consider redosing ammonia.

u think i should just remove the root tabs from the tank and toss them?

Did you check the tapwater as well ?

Honestly, yes I would.
And test your tap water too.

The tap water only has 0.25 ammonia in it and nothing else. no nitrite or nitrate.

Okay i removed them. My pogostemon helferi was really flimsy and sad. they disintegrated in my hand... and yeah i tested the tap. it only has 0.25 ppm ammonia

Not gonna lie…that nitrate test looks a bit off, especially the first photo. Maybe it’s lighting. I would do the test again.

yeah i see what you mean. honestly it looks orangy yellow in person but after looking at it reaaal close it seems closer to 5ppm nitrate. Ill do it again and post results in comments

It usually looks more like yellow orange or red orange when it is higher ppm but never brownish for me. Again, maybe it’s the lighting.

ohhhhh you mean for the older picture... yeah that was definitely lighting lol it was 10 ppm for the old one.
