For the first time in two years, not a single strand of hair algae had returned
I’ve been taking care of this pond for two years with weekly water changes. Filter service and debris removal. I also run an oversized UV sterilizer. The pond always looks great except for the hair algae on this waterfall that I remove every time.
After my first dose of Nualgi, I returned to the pond a week later and for the first time in two years not a single strand of hair algae had returned. That was proof enough for me! The only thing that differed from every other service was the addition of this product.
