The process will go like this: You will have your ammonia spikes, and you will have to do lots of water changes everyday to keep this down so your fish don't die. Next, you will get a Nitrite spike, and you will have to continue your water changes, so again, your fish don't die. Then, you will get a Nitrate spike, which is the final process. Once you are getting your Nitrate your Ammonia and Nitrite should level out to 0 and you will do water changes to keep your nitrate under 20.postal_blowfish wrote:@glitter ok that's something I can do. Now how will I know when it's cycle is finished? Where should the parameters be?
This process can take anywhere from 6-12 weeks. It's very stressful on your fish and that's why people recommend fishless cycling. However, since you already have fish you will have to do very frequent water changes and use prime to dechlorinate your water, which will help your fish out some.
The 50% water change that everyone does weekly after their tank has cycled is to keep the nitrates under 20 ppm (parts per million).
Best of luck! If you have more questions, feel free to ask. =]
