That was a very rough rule of thumb invented for the aquarium hobby, back
when we all thought it was pretty rad to have a 30g aquarium. It works
for
_small_ fish. The bio-load of a fish increase approximately eight-fold
every time you double it's length. The rule of thumb often cited here for
koi, is one koi in 1000 gallons, 100 gallons for each successive one. Not
a bad rule, as long as you don't cut it too close. 2 koi in 1000 gallons
can be tight.
====================
My larger pond is 2000 gallons with a cheapo Tetra filter and a settling
tank/VF I don't use the UV lights anymore as they're a real pain to set up
each spring and maintain. I have a lot more than 1 koi per 1000 gallons.
Next spring I have to cull a few more out. :-( As we get down to the
better looking ones it gets harder.....
