Welcome to FishLore!
Many people find it cruel to cycle a tank with fish in it, since the fish are exposed to deadly toxins during the cycling process. Now don't feel like I am scolding you, because due to ignorance I too cycled with some Danio's.
In order to treat your fish in the best manner possible during the cycle, you should do daily 50% waterchanges, using a water conditioner called Prime. The Prime will detox the
ammonia (and later nitrite) for 24 hours (yet still leave it available to feed the bacteria you are trying to cultivate) at which time you will be doing another waterchange with Prime.
Also, I would highly recommend getting the
API Master
test kit for Freshwater. This liquid test kit is know to be far more accurate than test strips. It initally costs morethan the strips, but it preforms many more test, so it turns out to be cheaper in the long run.
