I'm cycling a 55 gallon tank and I believe I may have missed the nitrite spike. After looking back on my notes of water parameters I noticed a small number of days of high ammonia readings ( 1 and .5) then back to the consistent .25 or 0. I've checked for nitrites after the first 2 weeks except for 2.5 days when I was out of town. I have not seen a spike in nitrites and am getting 0 for both ammonia and nitrites. I am getting small nitrate reading of 5. But I was told when using the API test kit nitrates may be thrown off if ammonia or nitrites are present leaving a false positive. Is it possible I may have missed the nitrite spike and am done or nearly done with my cycle? It's a fish in cycle FYI, and I am in week 3 and have filter media and substrate from an established tank in there.
