I have bought a property that has a tiny decorative pond with waterfall and sizeable filter. It looks as though a larger pond use to be in its place.
I plan to install this product: https://www.primrose.co.uk/500l-mayfly-preformed-pond-p-67263.html
I then plan to plant a mix of oxygenators and decorative plants (lilies) and then stock very lightly with some small, hardy goldfish.
Can anyone recommend what I should line the floor of the pond with? i.e. should I have part gravel, part soil, then let it settle? I am guessing that common garden soil and then small gravel to a thin depth is all that's required and then let the water clear before planting and adding fish
