Product Description
Simplify Whole-Pond Weed Control Without Mixing or Spray Gear
Sonar RTU Ready-To-Use Aquatic Herbicide is built for pond owners who want whole-pond weed control without the hassle of mixing, measuring, spraying, or launching a boat. This fluridone-based liquid is poured directly into open water, then works systemically through target plants and roots. It is especially useful in ponds with little or no outflow, where the treatment can stay in contact with weeds long enough to deliver season-long control.
Key Features & Benefits
| Feature | Benefit |
|---|---|
| Ready-to-use liquid | Skips mixing and makes shoreline application much easier for DIY pond owners. |
| Fluridone systemic action | Moves through the plant to control weeds below the surface, not just top growth. |
| 3-step treatment schedule | Supports a full-season program with Day 1, Day 21, and Day 42 applications. |
| 32 oz bottle size | Fits smaller ponds and partial-acre treatments without forcing bulk purchases. |
| No fishing or swimming restrictions | Helps you treat nuisance weeds without shutting down normal pond use. |

|---|---|---|---|---|
| Delivery style | Pour directly into open water | Measure and dilute before use | Spray over target growth | Broadcast pellets to treatment areas |
| Mixing burden | No mixing required | More setup before treatment | Usually spray prep required | No spray mix, but spreading required |
| Visible change timing | Often 3 to 6 weeks | Varies by label | Varies by label | Varies by label |
| Water-use context | No fishing, swimming, or livestock restrictions | Varies by label | Varies by label | Varies by label |
| Best fit | DIY whole-pond treatment in low-outflow ponds | Custom dosing in larger waters | Faster spot-treatment programs | Ponds needing pellet distribution |
Why Choose ready-to-use fluridone?
- Root-level control: Sonar RTU works systemically, which helps control target weeds beyond surface growth.
- Less setup: The ready-to-use format removes the mixing and spray-equipment burden that slows many pond treatments.
- Better buyer confidence: Label-backed water-use flexibility and a simple repeat schedule make planning easier.

My pond has had a major duckweed problem for over 5 years. Only 1 other product was able to get rid of it temporarily but I lost two koi fish. I used this last year in August when the duckweed was all over and my pond is still clear.
