Vicki is a homeowner in Charlotte, NC and has a smaller pond. She was getting ready to have family in a few weeks and wanted to make sure everything looked beautiful. She went out to check on her pond and noticed some weeds growing up from the bottom. She contacted the Clemson Extension office, and they determined it was Hydrilla, Eurasian Water Milfoil, and Curly Pondweed.

In what seemed like overnight, her pond had been taken over by the large beds of algae and aquatic weeds. She was so embarrassed for her out of town family to come.

Finally, after trying every product in the catalog, Vicki became a member at Platinum Ponds and Lake Management so she could ensure a healthy and beautiful pond. She was so relieved to know she would have a healthy and beautiful pond for her and her family to relax by when they got in town.

We knew Aquathol would be best for Vicki’s pond. Aquathol is an excellent aquatic habitat management tool that can provide season-long control of a variety of submerged aquatic weeds found in small lakes and ponds. It’s a selective and quick-acting contact liquid herbicide. It generally takes care of aquatic weeds in 3-4 weeks, but you could see results in as little as a few days.

Aquathol is not toxic to fish when used as directed on the label. So you can insert it below the water surface for submerged weeds or on foliage above the water’s surface. It needs to be applied on a calm day to keep the spray contained to target areas. For the best results, make sure the foliage is completely wet. Within a few days, before Vicki’s family arrived, her pond was back to being healthy and beautiful.

Due to the fast activity, it can be efficiently used in slow-moving water, such as drainage and irrigation canals. Also, spot or marginal treatments are highly effective against noxious weeds and algae in lakes and ponds. Since it does not bind to the suspended sediment or organic matter, it’s effective in murky or muddy water.
