Did a fishless cycle. Added fish Sunday the 4th.
Twice daily, I'm doing a nitrate and ammonia test, just to check on things.
Ammonia is always zero. Nitrite was zero both times Monday and Wednesday. This morning (Thursday) and Tuesday morning, I got barely detectable levels, a slightly darker blue than the zero reading on the API kit, but nowhere near lavender enough to be 0.25. So I classify that as "detectable but negligible."
Tuesday evening it had returned to zero. I will check tonight as well.
Are those barely detectable levels harmful, and is it normal to have a very very mildly detectable readings from time to time?
