Algae can quickly become a major problem for any pond or lake. Not only can it be an eyesore, it can also be detrimental to the health of your water and those who use it. In the United States, algae blooms are the primarily cause of fish kills. Algae can also damage water crafts and boating equipment. If your pond or lake is being overrun with chara, coontail, naiads, hydrilla, mil-foil, star grass, pond weeds, or other algae species, turn to concentrated Hydrothol Granular 191. This easy-to-use formula is also effective for many varieties of lake shore weeds. For over 30 years, Hydrothol has been one of the most trusted and widely-used herbicides/algaecides in America. In fact, it is the only registered organic broad spectrum aquatic algaecide available.
Fast-acting and effective even in slow-moving water, Hydrothol is a versatile choice. And because it will not bind to dissolved sediment, it can even be used in muddy sections of ponds and lakes. It is the premier choice for spot or marginal treatments. Use Hydrothol to clear paths in irrigational or drainage systems. Prepare your waterway for swimmers, skiers, or fishermen.
Feel comfortable knowing Hydrothol is the environmental choice. This granular dissipates quickly and does not bio-accumulate in the hydrosoil or fish. Therefore, when properly used, it will not adversely affect your pond or lake or cause toxicity in fish.
Following treatment, restrict domestic and livestock water usage from 7 - 25 days depending on application. To avoid trapping fish in the treated area, it is best to apply the granular outward from the shoreline or in strips. Apply with a spreader or scoop. See product label for proper application information.

If you own a body of water, you know that aggressive aquatic weeds can quickly become troublesome. Watershield, coontail, spatterdock, stargrass, water lilies, and especially the invasive Eurasian water milfoil all contribute to clogged intakes, flooding problems, and stagnant mats. Such overgrown vegetation can also rob the water of oxygen and increase sedimentation rates.
With Navigate, you have a strong ally. This granular aquatic herbicide targets and destroys some of the most persistent water weeds. Works as both a herbicide and a growth regulator for coontail, spatterdock, and milfoil. Helps suppress other species of difficult aquatic plants, including yellow water lily and bladderwort. The formula’s heat-treated attaclay granules not only decompose slowly to provide extended control, they also sink quickly to get right to the root of the problem.
Navigate Granular Herbicide should not be used in domestic or livestock water supplies. Nor should this product be used in water sources for agricultural sprays or irrigation systems. Application rates vary. One-hundred pounds per acre is recommended for treating milfoil. A maximum of 200 pounds per acre is recommended for resistant plants such as watershield and spatterdock. For best results, use in the spring and early summer. A second application may be necessary in areas of heavy regrowth or for sections that border untreated areas.
- 50 lb. bag
- 2,4-Dichlorophenoxyacetic acid, dimethylamine salt 46.8%
- Herbicide and growth regulator for coontail, spatterdock, and milfoil
- Helps suppress other species, including water lilies and bladderwort
- Gradual release formula
- Absorbed by leaves, roots and stems directly from the water.
- Works by inhibiting the weeds ability to produce carotene. Without this ability, chlorophyll is rapidly degraded by sunlight and the weeds die.
- 7 to 10 days after the initial application you will see bleaching at the growing tips of the weed.
- Results occur slowly - treat early in the season for an entire weed free summer.
Starting to see weed growth in your pond, lake, or canal? You are going to need a fast, effective herbicide. Aquathol K combats a wide range of submerged aquatic plants, including bur reed, coontail, pondweed, hydrilla, naiad, parrotfeather, and water stargrass. This concentrated liquid works on contact, quickly breaking down the plant’s cells. While full kill results often take one to two weeks, results can be seen in as little as one day.
Features a ready-to-use soluble formula that, because it does not bind with suspended matter or sediment, works even in silty and muddy waters. Product works best when water temperature is at least 50 degrees Fahrenheit. Application rates depend upon species of weed being treated, but generally range from 0.3 to 3.2 gallons per acre foot of water.
Though similar to other herbicides on the market, Aquathol K prides itself on leaving no residue and being easier and safer to use. This EPA approved aquatic herbicide is safer for fish, birds, and other aquatic species. While it is advised to wait 7 to 14 days before using treated water for irrigation, livestock, or domestic use, there are no restrictions on swimming or fishing in treated waters. See manufacture’s label for details.

Aerating shallow ponds can be a real challenge! Bottom placed diffusers work great for ponds 8', 10', 15', and even 20' deep but aren't always the best choice for shallower ponds. Our new diffused air tubing works great to aerate ponds that are 3-8' deep and works with our Aeration Windmills, AerMaster's and our LD 1.5 Electric Aerators.
This is self weighted tubing that has aeration slits to give you more air spread out over a much bigger area.Learn More
