Sorry, I just realized I didn't answer your basic question!
Fishless cycling, simplified: (have a read of this, then go back and see if the original threads you read make more sense.)
-The point of it is to mimic the fishes' natural ammonia (waste) production, thereby helping good bacteria to grow and process all the bad stuff.
- So, you have your bottle of pure ammonia, a liquid master test kit (try the API freshwater master test kit. Nutrafin makes one too, I think), and some kind of eye dropper / medicine dropper.
- Add about 5 drops of ammonia for every gallon of tank water. If you have a 10 gallon tank, add 50 drops of ammonia.
- Test the water. Is your ammonia about 6 ppm? If not, add a few more drops until it is at 6 ppm.
- Now the waiting starts. Next day, check your ammonia. Has it gone down? If not, wait.
- Keep testing and waiting until your ammonia level drops. Now, test for nitrIte. You should have some. Yay! Cycling has begun! Now, add a few more drops of ammonia until your test reads 3 or 4 ppm.
- Keep your ammonia levels right aroaund 3-4. Test every day, adding drops of ammonia as necessary. Your nitrites will eventually go sky-high then start to drop. When they drop, do a nitrAte test. It's the nitrate that's "eating" your nitrIte, just as your nitrIte ate your ammonia.
- When you have no ammonia and no nitrites, but lots of nitrate, you're cycled. Do a BIG water change and add your fish.
- a word of caution. After this big water change, add fish RIGHT AWAY. Otherwise, your new bacteria won't have anything to eat and they'll die off. Adding the fish (and the poo they make!) is just like adding ammonia. This keeps the cycle going. You just have to do water changes (around 25% or so) every week to keep the nitrates in check.
That's just a bullet-pointed, slightly streamlined version of the pinned topic, but hopefully that helps! Good luck! I know it's tough to give up the fishes (I adore my black skirts!) but it's better for them in the long run.
