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).

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.

Cute, comfortable waterproof boots (a little snug to put on)
Size: 7, Color: Velvet Tan/Gum 2
These are really cute Chelsea-style boots and feel very comfortable once they’re on. The waterproof material is great for wet weather and the sole feels sturdy with good traction. They look stylish enough to wear casually but still feel practical for rainy days. The only downside is they can be a little difficult to put on at first because the opening is somewhat snug, but once they’re on they fit well and feel supportive. Overall they’re a great waterproof boot and I’ve enjoyed wearing them.

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days. Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.
