Re-scaping a tank
I have a 2.5 gal tank, set up for 6 months now, that I am just not thrilled with anymore. I'd like to make some major changes to it, but it is currently housing a betta, and I'd like to avoid too much trauma. The changes will involve removing pretty much everything from the tank, adding fluval plant stratum (used, from a different tank), manzanita wood, and replanting some plants that are already in there, as well as adding some new plants.
What is the easiest way to do this? I was thinking about putting the betta in a bucket with water from the tank, and trying to work quickly. Should I add that same water back into the tank? Should I try to keep him temporarily somewhere else? If I leave the filter untouched, will my tank stay pretty much cycled, or will be starting a completely new tank? What, if any, of the new elements are likely to cause changes in the water parameters?
Thanks in advance!
