While I am stocking my new set up - I am looking at keeping an ongoing QT tank in a BioCube.
How do you keep it ongoing without anything in it?
Just a small dose of some sort of bacteria starter every day?
No damsel, please. They aren't suited to a tank that small, and would be outraged if you put another fish in: likely a fight to the death. Frankly, you don't need a cycled qt, and if you're doing tank transfer process (recommended: see: fish disease forum) a cycled qt is pretty well a no-go.
You still keep a fish in QT after the TTM, don't you?
OK, so yeah...
I just want to keep a 29 gallon BioCube running as a QT while I am stocking my new set up.
So I would just drop a few (5?) pellets of food in there every 3 or so days?
And then when adding a new fish to the QT - add some BIO-Spira or something?
I keep mine going with a few drops of Dr Tims ammonium chloride once a week, it feeds the bacteria and keeps everything alive. Clean, simple, and inexpensive.
