Nashville's "Natural" Pools: Chlorine Lies Fueling Yeast?
By Franklin Everett ShawForget the sterile, over-chlorinated public pools. Nashville, it’s time we talked about natural swimming pools.
These aren’t your grandma’s algae-filled ponds. They’re meticulously designed ecosystems that use plants and beneficial bacteria to filter water, creating a swimming experience that’s not only refreshing but also incredibly healthy.
Think of Radnor Lake, but swimmable and intentionally designed.
But why should a Nashvillian ditch the chlorine? Let’s dive in.
Chlorine, while effective at killing bacteria, comes with a price. It can irritate skin and eyes, exacerbate respiratory issues, and some studies even suggest a link between chlorine byproducts and certain health problems, including an increased risk of yeast infections, particularly in women.
Nashville’s humid climate already makes us susceptible to such issues; why add fuel to the fire?
Natural pools offer a gentler alternative. The water is softer, less irritating, and free from harsh chemicals.
But how do they work? It’s all about the science of biofiltration.
A natural swimming pool is essentially divided into two zones: a swimming zone and a regeneration zone. The regeneration zone is where the magic happens. This area is filled with aquatic plants, gravel, and beneficial bacteria.
These plants and bacteria work together to remove nutrients and impurities from the water, keeping it clean and clear. Think of it as a miniature, self-sustaining ecosystem.
Here’s a simplified DIY guide to maintaining a balanced natural pool environment:
Plant Selection: Choose a variety of aquatic plants native to Tennessee. Iris, water lilies, and cattails are excellent choices. They not only filter the water but also add beauty to your pool.
Gravel and Substrate: Use a mix of gravel and sand in the regeneration zone to provide a surface area for beneficial bacteria to colonize.
Water Circulation: A pump is essential to circulate water between the swimming and regeneration zones. This ensures that the water is constantly being filtered.
Regular Monitoring: Test the water regularly for pH, ammonia, and nitrate levels. This will help you identify any imbalances and take corrective action.
Manual Cleaning: Remove any debris, such as leaves and twigs, from the pool regularly. This will prevent the buildup of organic matter that can cloud the water.
Beneficial Bacteria Boost: Periodically add beneficial bacteria cultures to the regeneration zone to maintain a healthy microbial population.
Now, let’s address some common challenges. One of the biggest concerns is algae growth.
Algae blooms can occur if the nutrient levels in the water are too high or if the pool is not properly balanced. To combat algae, ensure adequate water circulation, maintain a healthy plant population, and consider adding barley straw extract, a natural algaecide.
Another challenge is dealing with cloudy water. This can be caused by suspended particles or an imbalance in the water chemistry. Regular backwashing of the filter and the addition of clarifying agents can help to clear the water.
Many developers face the pitfall of underestimating the size of the regeneration zone. A general rule of thumb is that the regeneration zone should be at least equal in size to the swimming zone.
Failing to provide adequate space for filtration will result in poor water quality.
Another common mistake is neglecting to properly winterize the pool. In Nashville’s climate, it’s essential to drain the pool partially and protect the plants from freezing temperatures.
Consulting with local experts is crucial. Several landscaping companies in the Nashville area specialize in natural swimming pools. They can provide valuable advice on design, construction, and maintenance.
Consider reaching out to Cumberland River Compact for resources on native plants and sustainable water management practices. They can offer guidance on selecting plants that are well-suited to the local environment and that will effectively filter the water in your pool.
Transitioning from a traditional chlorine pool to a natural pool is a significant undertaking, but the benefits are well worth the effort. You’ll enjoy a healthier, more sustainable swimming experience that’s in harmony with nature.
Imagine floating in crystal-clear water, surrounded by lush greenery, without the harsh chemicals that can irritate your skin and eyes. That’s the promise of a natural swimming pool.
So, Nashville, are you ready to take the plunge? It’s time to embrace a healthier, more natural way to swim.
