Exposure to water with Blue Green algae has been linked to long term neurologic disorders that don’t show up for years, such a ALS and Alzheimers. So it is important to prevent algae from growing rampant by not using synthetic fertilizers on our yards and gardens because they wash into our waterways. Even certified organic supplements should only be used when they are replacing a nutrient that is lacking. Simple measures with big long term health benefits for our families.
