After listening to EP50 of the TR Podcast (Congrats Rob, and TR community
btw) which had a main topic of cycling I decided to ask this question.
I've got both 3.7mg/l levels of
Ammonia aswell as 2.5mg/l of
Nitrite readings on my Hagen testkits (I know what Hagen can be like as far as reliability goes). I'm 3 weeks 5 days into my tank cycle, and I was under the impression that the
Ammonia would spike (slowly or otherwise) then drop to 0 or close to it. Then
Nitrite would increase it's levels, then do as the
Ammonia content did, and equalise... TR Podcast EP50 kind of re-inforced this, saying each chemical level would spike then equalise in turn. I've got almost off the scale levels of each, which is where my question comes in. What could I be doing wrong to get high levels of both?
I believe I've got a good grasp on concepts that I should understand at a beginner level to know what I'm doing wrong with most 'setting up' things (even if I have only implemented some of the changes in the last few weeks...). I have a 90G tank at 27c, 3" of calcium carbonate substrate, 2x T8 fluros (currently on a 1hr
photo period due to a
diatom bloom) a canister filter with sponge-bioballs-bioballs-cotton wool-sponge (I know the CF is a
Nitrate factory, and it will not be on my tank as soon as I buy/make my
fuge).
I've also (about a week ago) disturbed my substrate (approx. 50% of it) by removing an UGF I realised wasn't wanted. As bad as I feel for it, I do have a 1.5" Ocellaris Clown which seems healthy in all aspects (I wish now I'd spent more time reading books that were actually helpful before buying a life I could easily end).
I think my problem lies either with the Canister Filter, especially with it's clay bio-balls. Or perhaps with the fact I've upset my substrate and somehow disrupted the cycle. My other thought was the testkit was not reading properly, but I've tested for
Ammonia and
Nitrite every second day since the day my tank has been wet, and
Ammonia spiked like I thought it should, but just didn't drop once the
Nitrite test started giving readings. I've had the same
Ammonia level and an increasing
Nitrite level for a good week now. If any of these aren't a/the problem, I'd love to know what is, especially for 'Nemos' sake :S
Hope this post makes some kind of sense
Cheers TR people
