and am now in the waiting process for a
week to 10 days to do some tests and see if I can go ahead with putting
some Orandas in there.
Your tank will LOOK stable, but it won't be until you have the goldfish
living in it. As soon as you introduce your fish, your nitrogen cycle
will begin in earnest, your amonia will rise, followed by your nitrItes,
then your nitrAtes. Bottom line - GO SLOW when adding your fish,
depending upon the size of fish you add. The larger the fish you put in
- you do have a beautiful, large tank - the more careful you need to be
so that the cycle catches up with the waste output. Smaller fish = less
waste, so you can put more in, but then you still need to think about
their eventual size, so more than 6 is probably a bad idea in the long run.

You may want to consider products called STABILITY or CYCLE. These
products help establish the bio-filter while the tank is cycling and
speeds up the process. I know many dispute this, but these have been
invaluable to me when adding new fish.

Good luck.
