    Q: Will it kill turtles or fish?

    2 months ago
    1 Answer
    • A: Thank you for your question. When used according to label directions, this aquatic herbicide is designed to control weeds and algae and is not intended to harm fish or turtles. However, treating heavy vegetation all at once can temporarily affect oxygen levels in the water, so it is important to follow application guidelines carefully to protect aquatic life.

    Safe and strong killer for shorelines

    7 days ago
    This stuff worked great along our shoreline and is supposed to be safe for fish in the area so I give it an A+! It took a few days for things to die off, but you could see it improving each day. No more Elephant Ear Plant and other growth along our seawall rocks. Definitely recommended.
    SweepstakesYes

    Yes, I recommend this product.

    Worked on stubborn niasid weeds along the edges

    a year ago
    Worked well after second application, I added the algecide with it. Took a good week to die. But worked. It was gentle enough for me to use as we have our pond lined with a liner. I have never had underwater weeds before.
