Since natural swimming pools use the same biological processes of filtration and sanitation as lakes and streams, there is a theoretical risk of harmful algae blooms as seen above. These algae blooms have been known to close beaches, and are generally a result of excess phytoplankton growth. Blue-Green algae (Cyanobacteria) is the most common phytoplankton … Read more
If you’ve thought about ways to live a more sustainable life, you’re not alone. In the last 5 years, there has been a 71% increase in the popularity of searches for sustainable goods. With a large increase in the demand for swimming pools, as many people continue to work from home, it is worth discussing the relationship between these two trends. Of the 10.4 million swimming pools in the United States, just about every one is treated with chemicals, which is not sustainable by any means.
When we talk about naturally purified water in a natural swimming pool (NSP), biofilm’s role always comes up as a vital part of the process. What is biofilm in a natural swimming pool exactly? The answer is a bit complex but let’s break it down! What Biofilm Is Not Most people may think of biofilm … Read more
Diatoms outcompete less desirable forms of algae for nutrients in the water reducing harmful blue-green algae and filamentous algae (string algae). They are able to do this because they photosynthesize earlier and in less light therefore they are able to consume nutrients like nitrogen and phosphorus before the nuisance algae. Diatoms are the primary food source at the base … Read more
“Robyn’s piece goes to show that a global perspective on how we use the earth’s vital resources isn’t enough—you need to travel to the planets to get the big picture”. Dr. Anthony F. Aveni, Colgate University Professor of Astronomy and Professor of Anthropology Much of the talk today is about going to Mars and I’ve … Read more
