The "Fish in" cycle is the best for NORMAL people ..... not aqua enthusiasts. Do the nitrogen cycle with goldfish for a few days. When water becomes cloudy . then clear ...... it's time to return the goldfish and get guppies. And then add from that.
Even tho you don't want to believe it the bacterial bloom forming and clearing has nothing to do with the actual cycling of the tank. Just because the bacterial bloom clears doesn't mean your nitrogen cycle has run it's course.
All your doing is a fish in cycle but your not monitoring your ammonia, nitrite, and nitrate which is and can be very harmful to fish. If that's how you do it fine BUT advising others, especially new comers to the hobby that this is the "proper" way to cycle a tank just is not good advice.
As already stated doing a fish in cycle "properly" by monitoring levels and doing WC
's as needed to keep ammonia and nitrites at .25ppm or below is a perfectly safe and acceptable way of cycling a tank but this is not what your doing. Your basically adding fish and making them live through the spikes of ammonia and nitrite while the tank cycles, not a good thing at all for the fish which can die or suffer long term effects from ammonia and or nitrite poisoning.
I'm not picking on you and I hope you understand that but new comers to the hobby need to learn the correct ways to cycle their tanks.
