I thought this could be an interesting topic for discussion.
I realize that generally patience must prevail and the fishless method of cycling is preferred, but just as a discussion topic...
Do you think it is possible to instantly cycle a tank?
If so, how?
If not, why not?
I know there are products like Bio-Spira that claim to, and there are things you can do like putting a filter from a "clean" established tank onto the new tank. But does this give an adequate amount of nitriying bacteria?
There must be ways, otherwise how do people move, or move their tanks around, or tear them down and re-scape them?
Just incase you are wondering why this question...
I am considering re-doing the aquascape in my low light planted tank including new substrate...but it is full of fish and I am afraid of killing off too much of the beneficial bacteria
