Hey guys I'm cycling a 55 gallon with a small amount of live rock and live sand, bio spira, and pure ammonia. I'm at a point where my bacteria can take out 1.0 ppm ammonia in 24 hours but here's the part where I'm confused. For about 3 days in a row now, my nitrite and nitrate levels are stuck. Nitrite is anywhere between 2.0 ppm and 5.0 ppm (I can't tell exactly because on the API test they look like the same color to me). Nitrate is at 40 ppm. Can anyone please help me figure out why this is happening and how I can fix it? Also, I have been dosing ammonia every day so my bacteria should be well fed.

Thanks.

you are done cycling post pics of the rock and setup

(nitrite and nitrate no longer are factored in updated cycling science, only ammonia control is why I said that above)

nb4 stallers heh

when you mentioned live rock, that's associated with totally skipping the normal wait times, pics help us see % live used

additionally, biospira can do this below, that factored into why I stated you were done so quickly before seeing any other details:

why we dont care about nitrite and nitrate in cycling any longer: nitrite is neutral to us in every way in reefing. its expected to be present, but chemically neutral just the same, in early cycles. presence of nitrite messes up nitrate tests, only ammonia harms fish.

we are merely lucky your tester agreed ammonia is controlled, if it didnt, the tester would be wrong there still wouldnt be any lack of ammonia control given the details mentioned above.

Understood thank you guys. I was under the impression that the nitrites had to be dropped in order for the cycle to be completed.

This is great guys thanks. I’m still just confused on one thing. Wouldn’t the high nitrite, for example at the level mine is, kill my fish eventually? Or is that not true?

harmless 100%, wont affect any aspect of the cycle at all other than nitrate testing.



high nitrite tests above. we are only allowed to disregard old cycling rules if hundreds of tanks align with patterned outcomes...that's one of about ten threads I have on the matter testing high nitrite starts, and then months of follow up thereafter


the fish disease having nothing to do with the cycle turned out to be the killer of their fish, within 8 mos on average of setup.

At your levels, no. But it is true that nitrite and too high levels will kill fish, or even harm them. Nitrite needs to reach very high levels, like above 100ppm to be lethal: http://reefkeeping.com/issues/2005-06/rhf/index.php, though lower levels can cause long term diseases: https://link.springer.com/article/10.1007/s10499-015-9965-9.

So long as you keep nitrite below 25ppm, then it is perfectly safe for your marine fish. The reason why people may suggest nitrite is non-toxic is because, reaching 25ppm nitrite is very difficult, even if one 'screws up' the cycle. For example, you have been dosing ammonia everyday, but your nitrite is only between 2-5ppm, even though your nitrite-oxidizing capacity is still catching up. And that's far below 25ppm and likely won't reach 25ppm ever. So yeah. But I think it is still good to keep in mind what the truth is.
 

What is the best "cleaning product" or home recipe for cleaning reef tank equipment?
