goldfish and koi question
 

My 1000 gal pond of 3 years is home to only 6 goldfish and several frogs. I
am thinking of adding koi, now that I have some ponding experience. I know
koi need more room than goldfish, and my concern is that they will outgrow
my small pond. I am thinking of adding just 2 4-6 in. koi to so that they
are similar in size to the goldfish. My largest gold is about 8 in. and
smallest is 5. Any advice?

You can safely have 1" of Koi for every square foot of surface area.

We have a nice pond size calculator for figuring this out.

I can't believe they're still advertising that extremely antequated
calculation! You can _not_ safely have 1" of koi for every square foot.

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.....

I agree with Derek. There is a tremendous difference between 20 - 5" koi,
10 - 10" koi, and 5 - 20" koi. The size of the pond can be rapidly
overwhelmed by the so called rules. I also don't like filters advertised by
the size of the pond, they should be advertised by the pounds of fish,
pounds of fish food, or something relevant. One koi in a 50000 gallon pond
doesn't need much of a filter, but the same fish in a 50 gallon pond, needs
a lot of filter.

That calculator is too conservative. You should see my
cousin's hole in the ground. It has 8 square feet of surface
area, yet has at least 30 koi in sizes 4"-12". People keep
forgetting that we have high-tech filter and aeration, so
that surface area is almost irrelevant.

I'm sorry, but 30 fish in 2 feet by 4 feet is not a pond, it's
boulabaise.

I said 'hole in the ground', not a pond.

The total gallons of pond water and the rated size of your pond filter
is what determines the amount of fish you can have in your pond. A
simple rule we use is for every 1" (inch) of fish you need 1 sq.'
(square foot) of surface area assuming you have a good filtration
system. So, if your pond is 8' x 10' that would equal 80 sq.' of
surface area for new pond installations. That equates to being able to
stock up to 80 inches of Koi (10 8" Koi) to start with. For established
ponds with lots of aquatic plants and an active bacteria colony in the
filter, you can raise that level to 2 or 3 inches of fish per 1 square
foot of surface area.

That rule of thumb would allow you 11 koi, though - it's one for the first
1000, 1 for each 100 after that. It's intended for letting them grow out,
too.

Next spring I have to cull a few more out. :-( As we get down to the

LOL.
