To build a natural swimming pool is obviously something that most people won’t do. But in a country of around 60 million people, even if only a tiny percentage have a pool, that’s still thousands of pools that could be containing polluting chlorine and harming wildlife. If you have a conventional pool, ask your pool maintenance company about more eco- ways to clean your pool, they do exist. Also keep the pools covered when not in use, to reduce evaporation and prevent drowning.
Natural swimming pools are just that. They are like clean lakes, with various plants to filter the water, so you don’t need to dump chlorine in it. Obviously this will attract wildlife, so don’t do this if you are going to have the frights, if you come across a grass snake.
How to Build a Natural Swimming Pool is a book on how to build a wide range of pools from simple swimming ponds to plant regeneration areas that look like traditional pools. You’ll learn how to use plants to keep the water clean, and find info to limit growth of algae (blue-green algae is particularly toxic to pets). See make gardens safe for pets (including toxic plants to avoid near animal friends). Like ponds, ensure pools have sloping sides, for wildlife to get in/out.
Frog Log and Critter Skimmer (get both, they do different things) are good little inventions to order from over the pond. Both can help prevent small critters drowning in the pool (one is like a float they can use to get out, the others stops them getting trapped in skimmers). You may need more than one of each, depending on the size of your pool.
If you have dogs using pools, Doggy Docks are platforms that are easier for dogs to use than ladders, to get in and out of pools safely. You can also use them for boat platforms.
