We live in MIchigan and had a major problem with Duckweed. We are so glad that we found this item. We have a spring fed pond in our front yard that for years had been covered with duckweed so bad you could not see the water under it. It looked like a green carpet. We tried different things that people suggested even to getting a fountain to keep the water moving more. It took finding Lake Restoration and talking to someone who suggested Spritflo. We bought it figuring might as well tri it. After about 3 weeks it started killing off the duckweed. Shortly after that we could actually see the water again. Last year we also used it only earlier in the season before the duckweed was covering the entire pond. It is so great to see our large foot long goldfish that had started out at little 15 cent feeder fish to finally be able to see them. Bought more of this great stuff and treated it as soon as the duckweed started appearing. The pond is so clear we enjoy seeing the fish & the turtles enjoying the pond. Thanks to Spritflo.

I live in north Florida. My pond is 0.8 acre. It has been covered with thick duckweed for years. Finally researched and found Fluridone at Lake Restorations online. On March 15, I walked around the pond and waded in a little with a garden rake to push the duckweed back enough where I could put 1 oz directly in the water, not on the duckweed. I did this in 8 places around the pond using a total of 8 ozs. Within a month, the duckweed was dead and grey color not green anymore. 90 days later on September 15, I applied it again the exact same way. A few weeks later, the entire pond was clear. Nothing but water. I am buying another pint for next year in case it starts coming back. Completely satisfied.

I have a 1/2 acre pond that was covered in duckweed for 4 years. I tried numerous products and spent a ton of cash, not to mention hours. One pint of Spirtflo was poured in around the edges, 2 weeks later all duckweed was gone. Now 1 year later I have maybe 100 square feet of duckweed in one corner of the pond.

I have a shallow 1/4 acre pond and was advised by LR to use Spritflow for duckweed and possible watermeal. Required dose was 2 oz. I used 4 oz as per instructions of LR and nothing. They would not replace product or stand behind. Bad attitudes. Product failed for recommended use.

Poured a little in to a 5 gallon bucket. Filled the bucket with water and poured it in. I did this 4 times in 4 locations (north,south ,east, and west.) Only used 2 ounces total on my half acre pond. It worked great. No second application necessary.

I used this product to kill watermeal and it worked well. Took a while but the stuff is hard to kill. The only complaint I have was the lack of application instructions.

It does not work at all like Sonar. I used twice as much of the product as I use of Sonar and pond weeds are as bad as ever, 5 weeks later. Customer service is not helpful at all, with a condescending attitude. Weed is Hydrillia and I applied the product the same way I have Sonar or equivalent for the last 15 years. Price seemed too good to be true and unfortunately was.

The is the second year I have used this product to kill off the beautiful yellow water lilies that like to take over our 1 1/3 acre pond. It works very well. I will use it again if they come back.

We used Spiritflo (4 oz.) in our 1/2 acre pond to eliminate the duckweed. Two applications were applied 10 days apart. Within thirty days the duckweed was completely gone. Great product.
