[angelfish123]

hey i'm startin a new 55 gal tank, i got gravel and water in it, and the filters running. Prob get some hydrilla sometime this week, which'll help with the biological start-up. How long should i cycle the tank until i add some giant danios?

Read my article in General Freshwater labeled. Nitrogen Cycle (more than you want to know). It has all the answers you are looking for plus more.

You will need a source of ammonia before your cycle ever starts...

Here is some more reading info on cycling a tank..

3-6 weeks to do a fishless cycle. could be longer. if you know someone with a tank already or if oyu can get some gravel from the local fish store you can speed the cycle up. read the links.
