Granular algaecide that works
5 of 5 stars
By Rd in Manchester, TN on 02/24/2019

Granular algaecide works great to kill algae beneath the water. I use it around the edge where algae usually forms first in my pond. I apply when I see algae first beginning to grow.

By Steve in Cape Coral FL on 11/08/2024

I hate leaving reviews and only do it when I find a product that actually works. I used this in my mossy overgrown canal and it has cleared up the string algae and I have clear water now!

5 of 5 stars
By Riley in Blairstown on 09/16/2025

Every year my pond would get completely covered in weeds and algae. It looked like you could walk across. With Cutrine, it's crystal clear! It's simple to apply and highly effective.
