i am cycling the 125 gallon tank and was wondering is i could by any chance speed up the cycling by cycling it with some fish? the filters have been cycled before and the gravle hasn't been touched since it was drained, i washed some rocks and about ready to boil a peice of driftwood for it. i was wondering because my fish are desperately in need of a larger tank, hence why i got it. but i have to wait 20-40 days before i can get them more comfortable, is there any way of speeding up the cycling process, i have some hardy fish to put in if cycling with a fish is any faster, really they have no significance to me what-so-ever.
