How to Apply Sonar® Ready-To-Use RTU

Sonar® Ready-To-Use RTU comes in a distinctive squeeze bottle that only requires the user to lift the nozzle on the lid and squirt the Sonar® Ready-To-Use RTU directly into the water. Treating an entire lake or pond only takes a few minutes. After measuring the size of the water body, consult the rate chart included with each Sonar® Ready-To-Use RTU purchase to determine the amount of Sonar required. You’ll apply half of the total dose on day one, then return 21 and 42 days later to add the rest. Simply apply Sonar® Ready-To-Use RTU at two to four locations around the water body each time and the unique formulation of Sonar® Ready-To-Use RTU will disperse throughout the water.

    Sonar RTU

    Posted by Susan Waldhuetter on 17th Jul 2022

    Our pond was completely matted with duckweed, it was awful. I contacted Aquatic Biologists and they said to use Sonar RTU. It works amazingly well!!!! We have our pond back, my husband would have been so happy. Thank you!
