It's been 21 days and my fishless cycle appears to be complete now. I never saw an ammonia spike but I was out of town for 5 of the first 7 days of the cycle, I have seen a higher reading and it's been at 0 for a week or so now. The nitrites spiked at 3 and just last night dropped all the way down to 0. My nitrates are at 20.
Is it time to remove the shrimp, do a PWC
, and add a 1-2 fish?
From most of the posts I had read it seemed cycling would take longer than it has but I also noted that "every tank cycles differently"
Thoughts on if I should continue to let it sit as is for a few more days to be sure?
