day 15 fishless day 53 all together

7:30 am readings 24 hours after 12ml ammonia added to 3ppm to 4 ppm

Ammonia 0
nitrites 2ish
nitrates 40
ph 7.2
kh 3drops

temp 30C
added ammonia back to 3 pmm

last night at 645pm 10.5 hours afer adding 3 to 4 pmm ammonia

ammonia 0
nitrites 2to 5
nitrates 10 to 20
ph 7.2
kh3 drops
temp 30C

It means your ammonia eating bacteria are finaly established in sufficient numbers, and now you are just waiting for the Nitrite eating ones They usualy take about twice as long as nitrite eating ones, but can be quicker

good can't wait for this to be over but hey at least i am not having to do 3 + water changes a day now

Yes, if you think about that 24 hour report back there where ammonia was at zero and nitrites were 2ish... you saw that the A-Bacs were able to process 4ppm of ammonia down to zero (in 12 hours, and you were understandably excited) but actually the nitrite processing is something to be pleased about too as the A-Bacs would have produced about 10.8ppm of nitrite from that 4ppm amm and the N-Bacs processed that 10.8ppm down to about 2ppm, so the N-Bacs processed about 8.8ppm of nitrite down! Make sense?

Morning Lana, I guess the best part about this period of time is that you could just cut and paste the same stats and save typing.

Morning WD ,,, yup looking pretty much the same , have a good day off to work

Hum, where is that ammonia going? The nitrite is staying constant, as is the nitrate. One or the other should be raising... One of those two kits have to be dodgy, and my money is on the nitrite one Could you get your next sample verified at the LFS Iana? Draw a sample, test it, and take the same sample to the LFS for testing within 8 hours, just to ensure that your kit is working right

 

[waterdrop]

can't hurt, although I just think the nitrites are getting processed on through quickly to nitrates and then the nitrate increase is just getting lost within one of the color ranges of that test. We did already go through pretty definite ammonia dropping stage and then nitrite spiking stage.

i agree it won't hurt but i don't think it's actually necessary

the ammonia will be going through in a sort of steady trickle now, the fact that there's no nitrite reading showing just tells me that there's enough NBacs there to suck it all up before you see any reading. remember our test kits are only relatively accurate and wouldn't necessary pick up the trace amounts that are processed from the ammonia before they are turned into nitrite.

 

[rabbut]

Well, with ammonia going in for a few days, while the nitrite has remained constant and the ammonia dropped to zero within 12 hours, shurely the nitrate should have gone up, or the nitrite test kit is dodgy and nitrite is still on the raise... From what I remember of my fishless cycle, I could gain like 140ppm of nitrate in a week, so in too days, nitrate should have risen by arround 40ppm I know nitrate test kits aren't that accurate, but they should detect that kind of difference IMO

All the best
