Professional Systemic Aquatic Herbicide for Whole Pond Treatment

SePro Sonar A.S. is a selective systemic aquatic herbicide designed for comprehensive management of aquatic vegetation in fresh water ponds, lakes, reservoirs, and irrigation systems. With 41.7% Fluridone as the active ingredient, this professional-grade formulation provides season-long control of submersed and emergent aquatic weeds in water bodies with minimal flow.

Label and Instructions

Key Features

  • Systemic Action: Absorbed and translocated throughout the entire plant system for complete control
  • Selective Control: Targets aquatic weeds while preserving desirable vegetation when used properly
  • Long-Lasting Results: Provides season-long control with proper application
  • 41.7% Fluridone: Professional-strength active ingredient for effective weed management
  • Whole Pond Treatment: Designed for comprehensive treatment of entire water bodies
  • Minimal Flow Applications: Best suited for ponds and lakes with little to no water flow

Available Sizes

8 oz (SKU: SO8): Perfect for small ponds and initial treatments. Ideal for treating smaller water bodies or testing the product's effectiveness.

16 oz (SKU: SOP): Mid-size option for medium ponds and lakes. Provides enough product for moderate-sized water bodies or multiple applications on smaller ponds.

32 oz (SKU: SOQ): Professional size for larger ponds and extensive treatment areas. Excellent choice for serious pond managers treating multiple water bodies.

1 Gallon (SKU: SOG): Commercial-grade size for large lakes and professional aquatic management operations. Best value per ounce for extensive treatment programs.

How It Works

Sonar A.S. is a systemic herbicide that inhibits carotene production in target plants, causing them to lose their green color and eventually die. The key to success is maintaining the recommended concentration in contact with target plants for a minimum of 45 days. Apply early in the season, prior to or just after plant growth begins, for best results.

Important Information

This is a restricted-use herbicide and requires applicator certification in most states. Always follow all federal, state, and local regulations. Designed for minimal flow water bodies—consult the label for flow rate limitations. Does not control algae species.

FAQ

Q: How long does Sonar A.S. take to work?
A: You'll typically see initial signs of control within 30-60 days, with complete control taking 60-90 days as the herbicide works throughout the entire plant system.

Q: Why is the 45-day contact period important?
A: Sonar A.S. requires sustained contact with target plants for at least 45 days to be fully absorbed and translocated. This is why early-season application and minimal water flow are critical.

Q: Can I use this in flowing water?
A: Sonar A.S. is designed for water bodies with minimal flow. Significant water flow dilutes the herbicide and prevents the required 45-day contact period.

Q: Which size should I buy?
A: Size selection depends on your water body size and treatment goals. The 8 oz size suits small ponds, while the 1 gallon size is for large lakes or commercial operations.

Q: Will this harm fish?
A: When used according to label directions at proper application rates, Sonar A.S. can be used in waters containing fish. Always follow label restrictions.

Q: Does this control algae?
A: No, Sonar A.S. does not control algae species. It is specifically designed for controlling submersed and emergent aquatic weeds.

Q: Do I need a license to apply this product?
A: Yes, Sonar A.S. is a restricted-use pesticide requiring applicator certification in most states. Check your state and local regulations before purchasing or applying.

Q: When is the best time to apply?
A: Apply early in the season, prior to or just after plant growth begins. This ensures the herbicide has time to work and allows for the critical 45-day contact period.

Works for me
This is plugged into a Macbook Air M2 and it supports a time machine drive, a 4TB solid state drive, a wired keyboard, and a free USB port for plugging various stuff into. In this use case, some other hubs don't work well with the Macbook; it keeps forgetting hub-linked drives are there, dropping them when asleep or not seeing them after a reboot. That has not been a problem with this hub. It's true I lose some of that Thunderbolt speed, but really, 5 GB/s is not that small a hole to put stuff through.

Leave the Laptop at Home - Content Backups
Style: Data Transfer (10Gbps)
I purchased this hub so I could leave the laptop at home and do backups of my GoPro Cameras and Drone footage to an SSD drive. I used FilePro Explorer app on my iPhone to set up tasks to do backups of my content from the SD cards to SSD drive. The one hiccup I encountered is FilePro Explorer (or this hub, not sure which) wouldn't recognize my GoPro cameras as a data source, so I had to remove the SD card from my GoPro Cameras, insert the card into another USB hub that had an SD card adapter (like the one here https://amzn.to/4dlkhMt ) and plug that into the Satechi Hub as another drive source, which it then recognized my SD card from the GoPro camera. So basically two small USB hubs and an App on my iPhone replaced what I would normally do with my laptop. Big weight savings when you're on a bike or motorcycle traveling.

Flaky and Fickle
Style: Data Transfer (10Gbps)
Worked great for a month. Went to plug in a spare ssd to back up files from tablet and it never has worked since. No data or power through any ports. The light turns on and stays solid but is just dead. Waste of my money for now it is outside of return and I am having troubles getting in touch with Satechi.

Love this thing

I’m really impressed with my Satechi power passthrough 4 port USB C Hub. It’s really slick, streamlined, and really good looking too. It works well, doesn’t get hot or even warm to the touch.

Works, but man it is SLOW
TL/DR review follows: This thing does what it claims to do (gives you 4 USB ports that you wouldn't have otherwise), but the data transfer speed of any SSD I connect through this Satechi Hub is half what it is when the SSD is connected via my OWC Hub (data transfer rate is double when connected via the OWC Hub vs. being connected via the Satechi Hub). I'll keep this Satechi gadget (in a drawer) for times when I really, really need more USB C ports and therefore will be more willing to tolerate the data transfer speed slowdown penalty. I cannot possibly consider this to be a primary data transfer pathway however. These above results are from an M1 Mac Mini with 16GB RAM and MacOS Monterey with speed measured by Blackmagic Disk Speed Test utility. I did not get similar results on my 11th Gen Intel Core i9-11900 processor PC running Windows 11. Data transfer rates are the same (SLOW) when any USB drive is connected directly to the PC USB C port or when connected via the Satechi Hub. Highly worth mentioning, though, is that all data transfer speeds on the PC are HALF the speed obtained on the Mac Mini when connected via my OWC Hub. All PC data transfer rates were measured by CrystalDiskMark utility One interesting anomaly worth mentioning is that the PC will not eject USB drives if they are connected directly to the single USB C port on the PC BUT it WILL eject any/all USB drives if they are connected via the Satechi Hub. This particular PC has never been able to eject USB devices correctly. The Mac Mini ejects all these same USB devices correctly no matter how they are connected. All USB drives are formatted Windows NTFS whether connected to the Mac Mini or the Windows PC (for those who care) Conclusion: An interesting experiment, but for me the Satechi Hub is not worth what I paid for it. I can easily see it being a worthwhile investment for many, assuming undemanding use cases, however
