I can see the string algae dying around my rocks. The water is definitely clearer. Good going so far!
I promise anyone with green water. You will not be disappointed. It cleared my pond in 1 day. I’m amazed
I just started using it, I noticed a difference three days after the first application. Just made the second application three days ago and see more difference. If it will work on my swamp pond, it will work anywhere. Excited to see how well it will do.
I started it on Sunday and I must say the algae on my waterfalls just wipes off! It is crazy awesome!
Love Nualgi! It cleared up green water within two weeks and continues to provide crystal clear water. Recommend!
I started using it last year. I love it. In a week I went from pea soup to seeing the bottom. My pond is 25,000 gallons.
I have used it for 2 years and love what it did for my Pond and my fish.
I have a small pond and it was disgusting after the winter. Two applications and it’s looking so much better. I can’t believe that such a dosage brings such wonderful results!! So happy I tried it.
