I thought it may be fun to have a discussion on the natural swimming pools/ponds and peoples views compared to traditional swimming pools.
I have always been interested in natural pools and attended a few seminars etc. They are considered more beautiful by some and others like me regard them with a few cautions. We know a conventional swimming pool has sterile water so we know it's safe. It's difficult to have the same assurances when relying on the plants etc for cleaning the water. This point maybe especially important if you rent your property to paying guests. What assurances could you give in that situation, it's got to safe if the public are to use it.
The other question is on the landscaping issue. Personally I think the installers of natural pools are much cleverer with the look of the whole thing and the intergration into the surroundings make it look well, more natural. The hard formal designs of most swimming pools by comparrison make them stick out of the landscape especially with their common blue liners. (other colours are available!)
If you look at a natural pool that is more a swimming pool formal design, they too lose that relaxing natural look to me and in essence you have a pool which isn't necessarily as safe as a conventional pool but also doesn't look as welcoming as a natural pool would.
Interested in others opinions.
