hi I am toying with the idea of putting a pond in the back garden. I love frogs and have a 3ft tank with natural plants from the local area in it with some tadpoles that are nearly ready to leave the tank.

i have had a look at the options as I see them but would be glad of suggestion.

I have an area of about 5ft x 5 ft that is shaded for half the day. As far as I can see the options are
1 line the pond with liner
2 pour it out of concrete
3 buy a preformed plastic pond

I must say the 3rd option seem to be the most practical. I have been looking as the Oase filter and pump and I think the preformed plastic volume is about 1000ltrs

suggestions welcome. thanks
