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.

Super soft & cute
Color: Pink, Color: Pink
The color is amazing, between that & how soft it is, my brain is so happy about it lol. Matches my covers nicely (also got from amazon). The things shed very slightly, but I personally think its so worth it lol. I have a mini car vacuum & a lint roller, so its easy for me to keep it tidy anyhow. The bejeweled circle for a push to start, well I don't have that in my car. However the circle fit perfectly on my cold/hot knob lol literally the exact same diameter. Highly recommend this set, especially for this price.

Pretty in pink
Color: Pink
I’d totally give 5 starts but the middle console cover was too small and the cute little rhinestone ring didn’t fit the push button bc it’s not a flat surface. Otherwise I really like the rest. It’s a very soft pink. Does shed a bit at first. My cat loves the keychain puff.
