Amber C. – Koi & Gold Fish Pond

Algae removal for Koi Ponds

“I’ve struggled with green water in the ponds for years. So happy to see some good results! I can’t believe how much the goldfish have grown in a year! They were feeder fish when I bought them. And now they have babies!”

Charles R. – Pond Maintenance

“After first dose of Nualgi, I returned to the pond a week later & for the first time in two years not a single strand of hair algae had returned. That was proof enough for me! The only difference was the addition of this product.”
