Directions for use

Sonar RTU comes in a distinctive squeeze bottle that only requires the user to lift the nozzle on the lid and squirt the Sonar 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 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 RTU at two to four locations around the water body each time and the unique formulation of Sonar RTU will disperse throughout the water.
