Let me tell you about my war with duckweed. When I first got this product, my half-acre pond looked like a green carpet had been laid over it. I followed the instructions - mixed it in a sprayer, waded out in rubber boots (felt like a swamp explorer), and sprayed just under the surface.

The waiting game was real. After a month with no visible change, I nearly gave up. Then came the rainstorm that changed everything - suddenly all that discolored duckweed sank like tiny green ships, revealing crystal clear water for the first time in years!

Pro tip: This isn't an overnight miracle worker. The magic happens slowly as it starves the weeds of nutrients. Now I apply it preventatively in early spring before weeds appear - way more effective than playing catch-up later.

Yes, it's pricey (ouch), but seeing my grandkids actually swim in our pond instead of wading through green gunk? Priceless. Just be patient - nature works on its own schedule.
