Help with cycling
So my tank has been cycling with fish for almost a week. I bought test strips for ammonia(im getting an API master test kit soon). I've been doing water changes every other day to keep ammonia levels down to avoid killing the fish. My readings are maintaining 0.25 ppm consistantly.
Im just wondering if 0.25 is even enough to make nitrites show up. Should I let my ammonia rise to maybe 0.50? I only have 3 test strips for nitrites and nitrates so I don't want to waste them on readings of 0.
Basically, im trying to fing out:
-is 0.25 ppm ammonia enough to start the cycle?
-approx. How many days should it take for nitrites to show up?

Ok great! The water changes seem to keep the levels low and my danios are showing no signs of stress. Im assuming this is the main reason why cycling with fish takes longer. Thank you LH, I've learned a vast amount from your posts!

If you add too many fish at once, then you are fighting high ammonia levels daily. It's more difficult to cycle a small tank with fish than a larger tank due to the water volume. But......sometime people will get a large tank and over stock that one, too, so it works out the same.

+1 - as Lady Hobbs has said, it's necessary to keep the ammonia at .25 and not higher because it's the ammonia that 's needed to grow bacteria & feed them, but too much much will potentially hurt your fish - as you stated, that's why it takes longer to cycle with fish - without fish you can let the ammonia go higher, keep the temp higher and grow bacteria faster.
