Is algae in a pool harmful to people?
Generally, algae is not dangerous to humans. However, when swimming pool water is not taken care of for long periods of time, algae can grow and multiply and become a comfortable home for harmful microbes. It is the bacteria among these microbes that can have a negative health effect on swimmers if exposed to it.

Never mix with any other chemicals including cleaning products, weedkillers and chlorine products, as a dangerous reaction may occur. When pre-dissolving product always use a clean plastic container. If in doubt wash thoroughly before use. Always handle products in a well-ventilated area, preferably outdoors. When dissolving product always add product to water and not vice versa. Always wash hands thoroughly after handling pool chemicals. Store in a cool dry place. Instructions and dosages given are a guide for most effective use. Shake bottle before use.
