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).

Classy and sporty. Great value!
Color: Grey, Color: Grey
Excellent watch for the price. Looks sporty and dressy. More towards dress watch. Blue is dynamic. Strongly recommend blue for sporty feel. I was thinking of aqua terra. This come close to it with a price less than what i would have paid my state tax for omega aqua terra. My only concern is bracelet which i feel kind of OK. Better bracelet design would have made this watch much superior. 21 lug width is awful. Other than that, nothing to complain.

Stunning Gentleman's Watch
Color: Grey
This is my second Tissot watch. It's quite stunning in person. The online photos don't do it justice. It has the look and feel of a much more expensive gentleman's watch which makes this purchase a great bargain. Tissot is a great reliable Swiss made watch brand. My first Tissot watch which is probably more than 20 years old still runs great. Very pleased with this purchase.

Good Tissot Watch
Color: Grey
Arrived on time, in its original box, include a 2 year international warranty, into the box include a book with the Tissot brand history in Switzerland. Algo a second book with a whole catalog of Tissot watches men and women. The watch looks better when you put in on your wrist. The “naval” blue really gives the clock a classy look. The stainless steel workmanship is really good, the metal is bright and perfectly polished. The metal wristband quality is very good, did not have any problem to adjust the size , I went to my preferred clock workshop for this job, they extracted a few pieces of the band to fit to my small wrist size. Have to get used to the butterfly latch, but after a few days, now I learned to open and close it without any effort. The clock it’s very accurate, I’ve been using my Tissot for near a month and it just increased a few seconds per week. I do the setup and check accuracy with my pc clock. In short, It”s a good value watch, nice, good looking, accurate.
