Go with the Flow: The Beauty of Natural Pools

By Diane Small

When the temperatures rise, many of us wish we had a pool to dive into. But as refreshing as the traditional back yard swimming pool may be, they are also usually quite polluting, as they use harsh cleaning chemicals which are difficult to dispose of safely, and which can also harm skin.

Not only that, but the same chemicals can harm a pet or wildlife if they drink the pool water, and as most swimmers know, they can also cause dry and discoloured hair, red eyes and skin rashes. Even worse, trihalomethane gas, often used in pools, is a known carcinogen, and chlorine, omnipresent in public pools, has been associated with bladder cancer, asthma, and birth defects.
But worry not: natural pools are a perfect alternative. These fantastic pools are stunning all year round: during the winter they can freeze without problems, and in the warmer seasons, they are a verdant part of the garden landscape. They can even be constructed to look like small lakes and ponds rather than a huge, tiled hole dug out of the earth.
Wondering how to keep these clean? Luckily, there are a variety of different filtration options for these pools. Austrian company Biotop, for example,  offers households  two separate water circulation systems for optimum water quality and clarity.
The primary system uses a low energy submersed pump that runs 24 hours a day all year round and draws water down through fine grade chemically inert filter grit and a carefully selected mix of plant species that trap sediment, break down organic materials and remove nutrients from the water. This water is then filtered through a specially developed phosphate binding media and returned to the pool.

The second filtration system runs during the day and is connected to a biotop patented, self cleaning, self adjusting skimmer that takes all the surface water over a 8 hour period and clears any surface debris such as leaves to reduce the amount of wind-blown debris reaching the pool, and cuts down on cleaning.

These two systems working together provide some of the most reliable and efficient filtration available for natural swimming pools.

If you want to go even more natural than that, there are also Living Pools, which are slightly different. These are based on the same concept of Natural Swimming Pools, but function without the plants. Instead, they work by passing the water through a Phostec Ultra filter and biological filter medium to clean and clarify the water resulting in clean clear water all year round.


Finally, oxygenator technology can purify pool water safely.

This is a technology which generates four powerful natural disinfecting oxidisers from the water: hydroxyl (OH), atomic oxygen (O1), hydrogen peroxide (H2O2) and molecular oxygen (O2). Copper inoisation is then combined with the ‘oxygenator’ technology to guard against algae buildup. A high oxygen content in water means viruses, bacteria, yeast, fungi and protozoa are neutralised to the point where the pool water is actually fit to drink.

Whether biological or natural or oxygenated, there are certainly more organic–and beautiful–alternatives to the typically harsh chemical pools featured in most back yards.
