FAQ

What is Spritflo used for?

Spritflo aquatic fluridone herbicide is great for killing duckweed and submerged plants in bodies of water where there is no outflow. Fluridone works by staying suspended in the water for months, giving you complete and long-lasting pond weed control. This makes it a great pond herbicide!

What is the main ingredient in Spritflo?

The main active ingredient in Spritflo is fluridone 41.7%.

How do you apply Spritflo?

Spritflo herbicide application is very easy. Pour the correct amount of Spritflo into the pond, and it will work to kill pond weeds. This product does not need to be sprayed. It spreads itself evenly throughout the water and stays active for 45-60 days. *Tip: Triple rinse your bottle after emptying and pour the rinsate into your body of water. Fluridone is a thick, milky white liquid and this ensures that the entire contents of the bottle are applied.

Is Spritflo aquatic herbicide safe for fish?

Yes, Spritflo is 100% safe for fish. Because Spritflo gives you long-lasting pond weed control, it can help re-balance overgrown pond weeds.

Is Spritflo herbicide safe?

Spritflo herbicide is very safe to use in your pond or small body of water. Spritflo spreads throughout the entire water column, giving you more pond weed control. There are no restrictions for swimming, fishing, or livestock use. Please review the complete label prior to application as there are irrigation restrictions.

Will Spritflo kill duckweed or watermeal?

Spritflo aquatic herbicide works great at killing duckweed. Spritflo and all other fluridone herbicides are labeled for “partial control” of watermeal. These products are not recommended for watermeal control. Instead, check out our Watermeal Pond Products for a more complete solution.

When should I apply Spritflo herbicide?

Optimum pond weed control results are achieved when Spritflo is applied right before or right after weeds begin to grow in your pond or small body of water. Spritflo fluridone herbicide can be applied at any time. It can prevent aquatic weed growth and kill existing aquatic plants. There are no temperature requirements with this product. Apply Spritflo when:

  • there is no outflow from your body of water and
  • aquatic plants or pond weeds are present or will begin growing soon

When will I see results after applying Spritflo herbicide?

Typically, you will see results 30-45 days after treatment. Plant growth stops after Spritflo treatment. Weeds in ponds are killed in 30-45 days.

    The drop down is misleading. It states 4oz will treat up to 1/2 acre pond. My pond is .4 acres so I bought 4oz. After receiving the product and reading the label I actually need 24oz based on my depth. I wish the website was more clear on what is needed.

    • Katie Braton

      Thank you for the feedback, Al. This will be helpful for other customers. The Spritflo label is on our webpage and the average depth recommendations are on the Treatment Tips tab. We appreciate your comments and will work to be more transparent!

    It has been 30 days since I applied Spiritflo and there is no naiad dying. I feel like I wasted $700.00

    Update to my May 3rd review. May 15, 2024
    I contacted Lake Restoration and spoke to Katie. She was very courteous and professional. She asked that I send photos of the Naiad. She had Paul look at the photos and he responded promptly and said it looks like the Spiritflo was working and to give it a little more time. 5 days later it was obviously working. Lack of patience was on me. I expected it to work faster. Lesson learned have more patience. The prompt and courteous service is much appreciated. They obviously want to have satisfied customers. I apologized if I caused them any inconvenience. It is refreshing to see that there are still good businesses that are customer oriented. I will definitely refer Lake Restoration to everyone I know. Thanks again to Katie and Paul.

    • Paul Kretsch

      Benny,
      We are sorry to hear you have not achieved the desired results on Naiad control with the Spritflo you applied. Thank you for following up this review by getting a hold of our Sales Manager Katie. We are giving attention to the photos you sent, there is evidence of some of the naiad being impacted by the Spritflo(bleaching / redness). With it being day 35 post application, we will make sure we can see these results through to the finish.

    Good product, I use a little more than half the recommended yearly rate for duckweed, but I do it regularly here in South Carolina. I had a 3/4″ duckweed mat over 3-1/2 acres took a whole summer to clear; I already knew about fish problems ahead of time from neighbors. Nothing to do with the product; but, if you kill too much vegetation all at once, the muck reduces oxygen and big fish go belly up, smaller ones and minnows are okay.

    We have a fresh water quarry in eastern Massachusetts. I’ve used Spritflo twice in the last 6 years and it worked great. The wild life doesn’t seem to mind it

  5. Jeff Logue (verified owner)

    I put 4 oz in a 3/4 acre pond to kill duckweed and 2 weeks later all my fish died. Do not apply this to your ponds that has fish unless you got a heavy flow of running water feeding the pond.

    • Katie Braton

      Hi Jeff,

      Thanks for your feedback. I’m so sorry to hear about the fish kill. Spritflo needs extended contact time: 30-45 days for full results, and there should be no outflow so that the product stays in the water. There can be many reasons for a fish kill, and if you’d like to discuss the specifics of your pond, we’d be happy to talk with you. Give us a call: 763-428-9777 option 2. Looking forward to hearing from you!

    we have a small bass pond ~2ac that gets coontail pretty bad. I have used spritflo the last 2 years and it has done a great job of nuking it.

    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.

  11. Anonymous (verified owner)

    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.

    is spritflo selfdispersing ,can I just pour It In

  13. Anonymous (verified owner)

    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.

  14. Bryan (verified owner)

    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.

  18. Robert` (verified owner)

    I used Spritflo to eliminate hydrilla in my pond. After the ice went out in the spring, pieces of hydrilla were floating & you could see it growing in the bottom of the pond. I applied the product on May 5 & the hydrilla was completely gone in less than a month (I just did one application – I did not split them). It has also eliminated the small amount of duckweed in the pond & killed or stunted the grassy weeds that were growing. I have fish & frogs in the pond & they do not appear to have been affected by the herbicide.
