Dog Pond - Place a plastic kiddie pool in the ground. It'd be easy to clean and looks nicer than having it above ground. Big dogs can't chew it up or drag it around. This is obviously more fancy than a plastic kiddie pool underground, good idea thou
have to change stone and design but like see thru part!This is a very cool pool/waterfall setup. Something like this, with the neat underwater visibility, would probably be exceptionally cool in a koi pond.
Natural Swimming Pool/Ponds (NSP's) are a chemical-free, low-maintenance alternative to traditional chlorine pools. The water is clean, crystal-clear, and filtered naturally using a built-in biological filter. by kathrine
