How many goldfish, Chris? Are they multiplying for you?

Our pond is in the second category in the main pond is 2' deep and
about 2,900 gal. It is, however also functioning as a koi pond...tho'
not at the 10,000 gal level! The koi seem happy with it and have
grown large. The berm ponds are veggie filters and hold another 1,000
gal.
