How to Apply PondPak with Sonar RTU

Now you can take control of excessive aquatic weeds and algae with the SePRO PondPak. Nowhere else can you find one complete solution that provides season-long, do-it-yourself pond care delivered in one convenient package. All ponds are different and many variables must be taken into consideration when planning a proper treatment...but don't let that intimidate you. The actual application methods are simple and a SePRO pond advisor will gladly help you through the planning process. Read on to learn the basics.

Step 1: Captain* (Algae control): Day 1

Apply Captain at rate of 1 gallon per half-acre of water.

  • If pond is totally covered, treat 1/3 of pond at a time and wait 7 days between applications.
  • Mix 32 ounces Captain with 2 ½ gallons of water. Spray the algae until it turns purple-blue.

Step 2: SePRO Blue* (Water colorant): Day 2

(At least 12 hours after Captain application. No longer than 2-3 days.)

  • Throw in 4 packets for a 1-acre pond with an average depth of 4 feet
  • Throw in 2 packets for a ½ -acre pond with an average depth of 4 feet

Step 3: Sonar RTU (Weed control): Day 2 - 7

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.

No mixing, no need for spray equipment or a boat-simply apply directly into the water from the shoreline.

How PondPak with Sonar* RTU Works

Systemic absorbtion of Sonar
Systemic products are absorbed by the leaves, shoots and roots providing complete control of target plants.

An improper balance of nuisance aquatic weeds and algae interferes with your ability to enjoy your pond. Left uncontrolled, aquatic plants such as duckweed can upset your pond's natural ecosystem, affecting wildlife nesting and fish populations and making your pond unsightly. Weeds and algae can also ruin your recreational use for fishing, swimming and boating. Read on to learn how the different components of the SePRO PondPak work to restore natures balance.

How Sonar Works

Mode of Action: Sonar controls unwanted aquatic vegetation by restricting the plants’ ability to make food, causing them to die. This involves inhibiting development of yellow pigments that protect a plant’s chlorophyll from decomposition by sunlight. As the plant’s chlorophyll decreases, so does its capacity to produce food. The visual symptom of Sonar’s action is bleaching (turning white) on the terminal bud or growing points of the plant.

What to Expect: Sonar is selective and controls target weeds slowly. It lets desirable vegetation re-establish itself, and does not result in oxygen depletion or fish kill. Aquatic weeds remain under control for a full season and often longer.

It takes 30 to 60 days for Sonar to control the established weeds. You should expect full results within 90 days. You’ll be able to observe the visual symptoms of Sonar’s action as chlorosis, or bleaching, gradually appears on the terminal buds, or growing points, of the plant.

Plants in the intermediate range of susceptibility may require treatment at the maximum label rate. Typically these species are only partially controlled.

How SePRO Blue Works

SePRO Blue Lake and Pond Colorant is formulated to enhance the beauty of your water by imparting a natural blue tint and reducing sunlight penetration. The reduction of sunlight penetration into the water decreases the plants ability to make food for itself by reducing the light available for photosynthesis. SePRO Blue is not recommended as a standalone weed control product but may be used in conjunction with other products like the SePRO PondPak to produce the desired effects.

How Captain Works

The mode of action for Captain is uptake through the algal cells where the copper ion inhibits photosynthesis providing a fast-acting result. When treating an bad algae problem, you must split the Captain application into two or three treatments. Splitting the applications helps fish to adjust safely to the change in oxygen levels.

Algae is an aquatic plant that can grow anywhere moisture, light and nutrients combine to support growth. You certainly can't control how wet your pond is; and there's not much you can do about how much sunlight hits the water. You can, however, avoid fertilizing near the pond or anywhere rainwater runoff may enter the water.

How Revive Works

Revive is a formulation of natural microorganisms (bacteria) indigenous to soils and water. When added to ponds in sufficient numbers, the microorganisms utilize the available nitrogen and phosphorous, making these nutrients less available to unsightly algae and weeds that cause pond problems.

If aquatic weeds have impeded fishing, boating or swimming and made your pond unsightly, there is a solution: The PondPak featuring Sonar RTU from SePRO Corporation. Sonar is the world's leading brand of aquatic herbicide for the selective, long-term control of undesirable aquatic vegetation. Sonar makes water usable for recreation, brings the fish population back into balance and restores property values; all without any restrictions on post-treatment swimming, fishing or drinking.
