Using A Play Pond As A Tank?

[always4lora]

Just wondering if anyone's tried using a play pond type thing for keeping fish in? seems a cheap way of getting a large volume of water. I'd imagine the only issue would be keeping the water warm?

ive thought about this for my turtles. same really as a tank. just get bigger heaters/filters for the larger volume.
cheers

ahh sounds like a plan as theyre resonably cheap to buy and pond filters are relativly cheap

My daughter tried it for a while as an outdoor pond but the shallow water proved too easily affected by the environment. The ideal shape to prevent temperature fluctuations would be a sphere but that has lots of other drawbacks. The next easiest shape to maintain, for a 4 sided tank, is a cube. It presents the least surface to be affected by the outside environment. A squarish tank tends to be the easiest and most stable real world tank but it is not as pretty as a tall wide tank with a thin cross-section from front to back. Those tall thin tanks are considered showier than the more practical tanks that are called breeder tanks in the US. Everything that we do in this hobby is a trade off since few of us have unlimited space and funds.
