Algae may develop in the Berkey Light® Due to two factors. The first is that Berkey systems®Eliminate all chemicals that would inhibit algae growth. The second is the light. If the LED of the base remains permanently lit, it can promote the growth of algae. This can also occur if the Berkey system®is placed next to or near a sunny window where it receives direct sunlight.
This can be avoided by moving the system or not using the LED lights as much. Another resolution that our customers have pointed out to be very well working simply consists in placing a room in pure silver, such as an American eagle (99.999 %) in the lower room. Silver is a natural antimicrobial and inhibits the growth of algae. Although we do not know the exact type of algae growing, most blue-green algae are healthy food sources. We suggest you search for spirulina on Google for more information on the health of blue-green algae.
