Hydrothol Granular with alkylamine endothall is a selective, rapid-acting, contact herbicide and algaecide. Controls submersed weeds and algae in lakes, ponds, irrigation canals, and drainage ditches. Works rapidly enough to be effective in both still and slow-moving water. May be harmful to fish at recommended application rates.

Aquathol with a boost!

The physical form, mode of action, and general usage of Hydrothol Granular are similar to Aquathol Super K Granular. Where fish are present, application of Hydrothol Granular at rates over 0.3 ppm should be used only for spot treatments, narrow margins, or where some fish kill is acceptable. Do not treat more than 10% of a lake or pond at one time at application rates above 1.0 ppm.

When treating lakes or ponds with Hydrothol Granular, begin at shoreline and work toward center. Apply parallel to the shoreline. This will herd fish away from the treated area into deeper, untreated portions of the lake or pond.

Treat your entire pond for algae.

Lakes and Ponds:

Algae can be controlled with as little as 0.2 ppm of Hydrothol Granular when the entire pond is treated. For longer term control or spot treatments, use 0.5 to 1.5 ppm. Repeat treatment when growth reappears. For floating mats, scatter uniformly over the surface of the mat.

Weeds can be controlled with 0.5 to 3.0 ppm of Hydrothol Granular.  For most Pondweeds, 1.0 to 2.0 ppm will give excellent control.  When treating an entire pond you can use 25% to 50% less material.  

To determine pounds of Hydrothol Granular to use per 1,000 sq. ft.:

(application rate in ppm) x (average depth in feet) x (1.25) 

To use 1.5 ppm at an average depth of 4.0 feet:

1.5 x 4.0 x 1.25 = 7.5 pounds per 1000 sq. ft.

Canals and Ditches:
Irrigation canals or drainage ditches will require 3.0 to 5.0 ppm of Hydrothol Granular.

To determine pounds of Hydrothol Granular in canals and ditches:

(application rate in ppm) x (1000's of linear ft.) x (cross section in sq. ft.) x (1.25) 

To use 3.0 ppm over 2,000 feet with a cross section of 15 sq. ft.:

3.0 x 2.0 x 15 x 1.25 = 112.5 lbs.

Treat heavy infestations in sections of 1/3 to 1/2 of the total weed volume to avoid oxygen depletion.  Allow 5 to 7 days before continuing to untreated sections.

See Water Use Restrictions (Days).

Great quality, color is ok.
Color: Cream Brown, Size: 2 x 6 ft Sheepskin
The quality, texture, feel and smell of the rug is very good. The hairs adhere to the back lining well and don't shed even with my cat trying to bite it out. The only downside unfortunately is aesthetic— the cream brown I ordered, in natural light/sun shining on it, looks more yellowish - gold.

Great Quality!
Color: Ivory White, Size: 2' x 6' (Sheepskin Shape), Color: Ivory White, Size: 2' x 6' (Sheepskin Shape)
I have owned many sheepskins before and this one is by far the best deal. Cheaper than similar sizes, but not in a bad way! It’s a beautiful creamy white, super plush, and is very long. We keep it on the back of our couch and it gives a very cozy vibe. I haven’t had any issues with it shedding. Word of advice for cat owners: When we first got it, it did have a sheepskin smell but it isn’t a gross smell and it went away within a few days; however, my cat was very attracted to that smell and was “attacking” the sheepskin. We trained her not to do it just by spraying her with water—after a few times of that she stopped going anywhere near it. Now that the smell has dissipated, she isn’t attracted to it anymore but does like to sit on it every once and awhile (I can’t blame her, it’s sooooo soft). I saw someone else say their cat ruined their rug, so I wanted to give our story on how we prevented that and hopes it helps another cat owner. You just have to be alert for the first day, maybe even let it off-gas outside first, then keep a spray bottle nearby and the cat should stop messing with it!

Great little rug!
Color: Ivory White, Size: 2' x 3' (Sheepskin Shape), Color: Ivory White, Size: 2' x 3' (Sheepskin Shape)
This nice little sheepskin rug is the perfect finishing touch to my little reading nook. It’s soft and thick. Follow the enclosed instructions to fluff it up. I was going to order a second one but saw that the price jumped nearly $10 in a week. It’s nice but it’s not worth that amount. I’d buy it on sale though. Five stars.
