Let's talk about cycling a tank
I like to think I have my head wrapped around this idea pretty well. But I am starting up a small 6 gallon, which is my first tank in awhile.
Part of the discussion is where does this "good bacteria dwell?"
I ask because I got 3 gallons of water from an established tank. (The filter,sand,rocks in the new tank are all relatively fresh).
In my mind I basically just did a 50% water change.But I also understand that bacteria may also live in the filter media and sand.
Second question. If you used 100% all established water, would it crash the cycle if you are using a new filter and new sand?
I ask these questions because I am impatient but I also what to know more about the science behind creating this safe ecosystem.
I also ask these questions because I see shoes like "Tanked" where they fill the tank and add fish imediately. I assume they either treat their water with chemicals, or have large tanks of properly cycled water and use aged filter media.
Side note, how are snails impervious to ammonia but other inverts(shrimp) are so quickly affected?
