Chemical cycling for a fish tank?

you don't need chemicals talk to your local pet store and get what I call gravel water it is water that is siphoned from the gravel it will be loaded with the good bacteria the more you can get the faster your tank will be cycled and even though people donot agree with this next statement it is true over 90 percent of the bacteria is in the gravel not in the filter for those that say I am wrong like mr. soup nazi what good does the bacteria do in the filter when all if not the majority of excess food and fish waste end up on the bottom of the tank hmmm what an interesting concept
