Upon recommendation from a local pool shop, I added 2 ounces of HTH Super Algae Guard to my 5000 gallon inground swimming pool because ducks were getting in it. Supposedly, the algaecide makes ducks less buoyant in the water to where they avoid swimming in it. Something had to be done because they were basically using my pool as their personal bathroom. The amount of poop that needed to be cleaned out on a daily basis was nothing short of incredible. I saw this as a major health hazard due to the pathogens present in duck feces. The algaecide has worked for now (first duck free day in 2 weeks), but the water pouring over the spa spillover is making bubbles at the immediate area and the surface of the water appears to have a more oily texture. Is the added algaecide and the effects it has on the water a health hazard and do these treatments have any link to cancer? Is the pool safe to swim in at this point after extracting as much of the duck feces as possible?
