There is something about this cycle thing I just don't get. I have read the article and posts a few times. Please bear with me and don't laugh too much...

My established 10g's bacteria will be used to populate my new tank, probably a 75g but no less than a 55g. Assuming the new tank is set up properly and heater, larger filter, etc, are all humming along for 24 hours or so, can I just transfer my 10g filter (Fluval plus 2 -rated at 105g/h) and the fish to the new tank at the same time? I would not be adding any more fish until I was sure everything was stable again. (Eventually the Fluval plus 2 would be returned to the 10g for new fish QT). I do not like the gravel in the 10g so that will not be transferred, but all the plants, the coconut caves, the bogwood, and decos would go to new tank.

Questions: Does the increased volume of the new tank somehow "dilute" the bacteria colony? Are my 10g fish in danger by doing this quicky transfer? Should I throw bioballs in the 10g now to grow extra bacteria? How many for a 55/75g? Can I dispense with transferring the Fluval if I have enough bioballs?Then, can I do the reverse by putting the Fluval 2 plus back into the 10g and QTing a few fish at a time? Should the gravel in the 10g be discarded or washed before adding QT fish? I guess I am afraid that I will kill off my good bacteria somewhere along the line and be forced into a fishy cycle.

That should be fine. Your fish will still produce the same amount of waste, and your filter should be able to handle it. Once the bacteria is established it doesn't take long to spread out around the rest of the tank and grow to the size needed for your bio load. If you do add more fish eventaully just add them gradually.

That being said, just keep an eye on it and be prepared to do some water changes just in case. You do loose some by not transfering the gravel. I think it would be fine though.
