Default Quick Question

Once again it depends on the size of a tank, one small fish in a 100+ gallon
tank thats planted (even without lots of light, CO2, and fast growers) could
probably live indefinitely without a water change or any filtration. You
can probably do this same setup with med-light plants, not fast growers, and
no CO2, as long as you do the stocking a little slower.

Bear in mind that the bacteria that live in the filters need ammonia &

you put a mature filter into a sterile, clean tank it will actually die
back - so putting a few fish in at the same time is very much the way to

Check for ammonia & nitrites for the first week or so - you may never

any if you do it right.

I'm happy you posted this. I've always had a tank around and have cycled
my tanks by using aged media. I read in other sources how it can take a
tank a month or so to cycle, but using the method you describe (with a
light fish load the first month) I've never measured an ammonia or
nitrite spike.

I would like to add that I would not slap in delicate fish or more than
two or so fish while the tank is settling in, even with this process. At
least until your fist scheduled water change.
