If you're asking how to build a bog the simple answer is it's a gravel filled area that is plumbed from the bottom. Water comes up through a series of pipes and flows up through the gravel, through the plants and into the pond. I guess in theory you could use a kiddie pool.
And you can keep the water from being disgusting without concerning yourself with testing for pH and other parameters. You just need good filtration.
