fish for cycling

Good deal, using media from your existing tank! Make sure you put in a little bit of food.

There should be some bacteria on that media if it came from your tank. You could probably pick out a fish or two and add them right away, since they would provide the food source for your bacteria. Just watch the parameters and water change as necessary.
 
I have also read that certain factors can help a cycle, and bacteria growth. This being said, It is my belief that new fishkeepers who are starting cycles for the first time would be better off using "general" information/practices. Frankly there is way too much that someone can do to harm thier bacteria/cycle if one tries to "tweek" every varible in order to shed a week or two off a fishless cycle.

Sounds good to me. Check this out: just fyi re "fishless" etc

bacteria will do fine in any pH. it really isnt an "issue" if you leave the pH alone and it stays stable.

Here is a link and a quote from the article. There was also an article in Tropical Fish Hobby (? Title) about a month ago explaining the FACTS about nitrifying bacteria that supports this information. I dunno, I think I will stick with guys that have few credentials on this one.


pH

The optimum pH range for Nitrosomonas is between 7.8-8.0.

The optimum pH range for Nitrobacter is between 7.3-7.5

Nitrobacter will grow more slowly at the high pH levels typical of marine aquaria and preferred by African Rift Lake Cichlids. Initial high nitrite concentrations may exist. At pH levels below 7.0, Nitrosomonas will grow more slowly and increases in ammonia may become evident. Nitrosomonas growth is inhibited at a pH of 6.5. All nitrification is inhibited if the pH drops to 6.0 or less. Care must be taken to monitor ammonia if the pH begins to drop close to 6.5. At this pH almost all of the ammonia present in the water will be in the mildly toxic, ionized NH3+ state.

This rest of the article will discuss oxygen, temp, and other information pertaining to the cycle.
