Many thanks for your reply MW, I see what you are saying completely.
The only part I have a question about is the section I have quoted here:
However if I have 'just' finished a fishless cycle (oh I wish!), and my filter is processing 5ppm ammonia to 0 in 12 hours, I believed this to be representative of the waste of a heavily stocked tank? If thats the case then I would presume you can go for perhaps a quicker initial stock than you could if adding to a tank that had already allowed it's bacteria colony to die back to match the current stocking levels? (Of course you still have to allow for the Cycled Vs Mature issues though)
The only part I have a question about is the section I have quoted here:
I understand that if my tank has been running with fish in it for x amount of time, that the filter bacteria will have 'balanced' themselves to cope with these fish, no more, no less, and so to increase stock has to be done slowly....but remember that however you do it when you're going from an existing cycled filter and building up the stock you have to do it slowly anyway.

) my original tetras were stuck in until I got the 35g for them and actually had 2 box filters in one side and a HOB on the other of that new tank for the first 2 or 3 months - although appearances don't concern me so much regarding such things, whereas normal people are different, lol.
