Guide to Water Cleaning

Natural Pools and high quality ponds employ a number of methods to keep the water clean and clear without chemicals like chlorine or salt (which is used to make chlorine). The most important element is a built-in biological filter. This is not an off-the-shelf filter (like a sand, fluid-bead or cartridge filter): We're talking about a powerful, engineered filtration system that is built into the pool/pond itself. This bio-filter is the heart of the natural pool and the system won't work without it! Read more about the biological filter here. 

​Other types of water cleaning systems are used in natural pools and ponds to supplement the biological filter: These include Skimmers, UV Sterilizers and Algae Controllers.
