ok i have built a few out door koi ponds for my mom over the year's. a few thing's i learnt. get a uv {atleast had to for outside} ill find out exactly where, but i do believe she got here liner at a hardware store. maybe it was hd. but ill check. last one i built was 8x6x6 with a 4' waterfall. is this going to be for fw or sw ? might really make a differance in type of liner. pre-wash liner either way.{ make liner secure in case you ever have to get into it} thought about seeing if landlord would let me build one at my house now for outside. be interested in following this thread once you decide what to do. id definately use block as the frame or support though. or buy a kids swimming pool. one of the small one's that are 3' or 4' deep. be alot cheaper to do and will give you about everything you need.
