Still haven't been able to work on the filter yet. I have been having trouble finding any terra cotta pots that aren't glazed and dont have a how in the bottom of the pot for drainage. The ceramic pot is porous which makes it possible for water to pass through the material. As the water moves through the ceramic many of the pollutants are removed. It's pretty cool stuff. The water will then get to the sand. After about 2 weeks of water trickling through the sand the top 5 inches or so of sand will create a biofilm consisting of bacteria, protozoa, and small little creatures that work together to clean the water. It sounds kinda strange that our water is cleaned this way but it's true. I may also include an activated carbon filter just like those used in brita water filters, but I haven't decided yet.
