Hi I am looking to make a pond for all my goldfish, koi, and shubukin goldfish. What would be a easy to make and cheap pond for these guys??? I have seen people using blow up pools and kiddie pools will this be ok??
Let me know

Look at Mr.A's post here

Heh. I use a lot of these actually. All of mine are inside, the winters here get too nasty for anything to make it through them.

One: Do not use blow up pools. They suck, they deflate, the air gets out and they need regular tending too.

Plastic Wading pools: $5-$10
I have and use, plastic "wading pools" They're often seen in the summer at any toystore/walmart type place. Mine are 4' diameter and 16" tall
Pros: Cheap, sorta sturdy.
Cons: Not very tall, 16" deep was the biggest I could find in my area. Fugly colors that fade in the sun.

Metal Frame Pools. $65 at end of summer ($110 originally)
I picked up one of the Intex brand ones on clearance at Target the end of the season a year or two ago and it's nice and big. Mine is the rectangle and is 10'x12'x2'
Pros: Cheap for it's size. Comes with a pool filter too.
Cons: It's just a metal frame that a heavy molded pond liner fits into. I wouldn't use it for anywhere that has a lot of traffic or where things could rub into it. (Here it's in it's own room) Also heating the thing is a bitch if you need to.

Concrete Tubs: $13
For smaller stuff, I love these. Lowes carries them in the concrete section. They're made by MacCourt, the same company that makes the hard frame pond liners.
They're 2x3x1' (55g) and I keep pond plants in them and small feeder fish as well as hatchling turtles and torts.
Pros: Cheap, sturdy and easily put in rows together.
Cons: Small.

Hard Pond Liners: $50+
I'm not as much a fan of these since they all seem to come in oddball shapes. They're sturdier and deeper than the wading pools, however not as sturdy as the concrete tubs or livestock tubs. I have a few since they were free, but the weird shapes make them hard to use.
Pros: Step-up from wading pools, deeper
Cons: Weird shapes don't fit in easily.

Flexible Pond Liners: $1ish a sq foot,
If your handy with wood, these are nice. Like the metal frame pool, only you can build your frame as sturdy or with whatever materials you'd like.
Pros: Build any size pond you have room for
Cons: Large runs are neigh impossible to work yourself.

Livestock Tubs: $60+
For me this is the gold standard in above ground/indoor ponds. Super sturdy, pre-plumbed and made of awesome. I have Rubbermaid and Tufftub brands here and they're great. They're meant to survive the abuse of farm animals, you'd have to work to kill them. Farm stores like Tractor Supply (Tufftub is the Tractor Supply house brand I think) and Agway carry them.
Pros: Sturdy, oval shape, easy to filter, up to 300 gallons
Cons: Heavy. Anything past the 100g you'll prolly need help moving.
