Never worried about it! It's a year old and before it got cold we were swimming in it 3-4 nights a week. Got a aquascapes filter system and tons of plants. Treat it once a week with beneficial bacteria and it is as clear as you can get. Posted via Mobile Device
Do u have any info or data to support. This is far from a new concept and is actually becoming a very popular concept. Over a year old and no issues. Posted via Mobile Device
There is mountains of data attesting to the existence of aquatic pathogenic organisms and exactly what it takes to maintain safe levels in human immersion facilities. The fact that these types of swimming venues are not approved, or even recognized for that matter, by the two (2) leading health organizations in the world, the CDC and the WHO should be enough to give one pause.
A small water feature we just complete in SW Portland. More pics: http://www.houzz.com/projects/1414399
Are you pumping water from the big pond next to the water feature? I don't see a skimmer anywhere. What are you going to about all the cobble/river rock that's going to slide in to the bottom of the pond?
Waters coming from the lake, that's where the pumps located, and returning back there. Pond has a step around the side, where larger stones are set, supporting the others. Pond is about 1.5' deep at it's deepest.
The flagstone pathway is... well sloppy. The pondless steam, plant material, and boulder bridges turned out perfect.
