Cycling a Tank (shrimp related too)

I'm trying to collect data on cycling a tank because I'm trying to do so with (2) 10 gallons. From reading this is what I gathered. I'll gather some more when I get home from work.

I just want to go over it with everyone to see if I got my facts straight

1. You know your tank is cycled when ammonia is near 0 for a straight few days, even with partial water change (25%ish)

2. A cycling tank has a reading of about 0.25-0.50 ppm nitrate, and x ammonia?

3. Fastest way to cycle a tank is using old substrate/filter from another tank. Adding plants will not stop it but help it. Fish is similar, add some hardy ones to help with cycling. With this cycling can be as fast as 2-3 weeks.

Is there anything else I'm missing, someone fill me out. I'm trying to cycle a tank fast so I can add shrimps. I've been cycling this other tank for a little over a week already.

Questions:

Whats the parameter readings before cycling a tank and after cycling it?

I'm keeping cherry shrimps and I was wondering whats their tolerance level when it comes to nitrite and ammonia? I know 0 for all is of course the most ideal but what can they really handle?

The readings will be low at first. After a week or so, you'll get high ammonia readings that'll last for several weeks. Even with goldfish, it took my 12g 4-5 weeks.

You can speed it up using bio-spira... I use it every time I start new tanks.

So when do you know that your tank is cycled or is what I said in the first post correct?

What you've said is good. I would wait until I have at least 4-5 days of 0 though...

The fastest way I've cycled a tank is just by adding ammonia everyday. I believe it took me 1-2 weeks max. I followed this method.

Excellent article, Volatile!

You're definitely on the right track, Natty.

Here's 2 more good ones on fishless cycling:
