Pond Filtration, Pond Maintenance and Aquarium Maintenance, UK

This is what the bottom of a pond looks like after only a few years.

Notice that the sludge is right up to the ledges (you can see one at the front of the pond and one my brooms sitting on to the right)and this is after a few years. Pond muck gets into your skin it stinks and it's not easy to get out, just in case you want to clean your own pond, it's not nice.

The bucket of frogs you can see in the forground all came out of this pond and the owner said she had a few frogs, theres are dozens of them. The other live stock is in a crate full of water happier with out being crowded by a lot of frogs.
