Hydrothol Aquatic Herbicide 20# Bag- Endothol 11%

Seems to work on curly leaf pondweed -- especially when treated early enough (about 50F water temp).

Cleared out stubborn algae in just a few days. Easy to spread and works fast without harming the fish.

Why did you pick this product vs others?: Works great on lake weeds. Unfortunately expensive and takes a full bag to do the job.

Order received on time and in good condition. Seems to work fine.

Didn’t work for me.

This is my second bag of this. I use to control weeds off the dock in Minnesota. Seems to do a good job when applied early in the spring then reapplied a few weeks later. Does not help with tougher plants like cattails.

Hydrosol pond weed killer. Use this to control weed growth in my pond. Safe for fish, animals and humans.

Great product
