Most of the preform ponds are smaller than 220 gallons. Generally speaking
they are too small for koi. A general rule of thumb used on rec.ponds is to
have 1000 gallons for the first koi, and 100 for each additional koi. Koi
grow large. My average size right now is probably close to 2 feet long.
The preformed ponds will definitely grow into larger liner ponds, or drive
you out of ponding if you have koi. I started with two preform ponds, some
goldfish, koi, and catfish. The catfish went to a farm pond at the end of
the first season. The preformed ponds got a liner pond added to the system.
The preformed ponds sprung leaks and got replaced with another liner pond.

If you want koi, start with a liner pond. Large ponds are more stable than
smaller ponds. If you want only a small liner pond, consider one of the
types of goldfish.

Im moving to a townhome that only has a 18' x 22' yard. I was
thinking of getting one of those hard liners and building a raised koi
poind. I want to get at least 3 - 5 koi what size of a liner do i
need. remember I want one that is already molded.

Also if some one can point me to a site that might have a setup like
the one i want with the FAQs and howto set it all up that would be
great.

Thanks,

Rigz
