Crystal Blue Copper Sulfate Algaecide - Granular Aquatic Grade Copper Sulfate for Pond Algae Control - 5 Pounds

Worked really well. We had horrible, thick algae across our pond. This product cleared it up within weeks, after only 4 applications.

A spray of this works perfectly in destroying any algea from our pond.

this stuff is the way to go in the pool

I had purchased a container that looked like the picture a year ago. When shopping to replace it, I bought this one thinking it was the same. But it’s my fault for not reading that I was buying 5lbs. It’s still a good product but I think it’s deceiving.

The media could not be loaded. Works fast in 24 hours the algae was gone, the color was beautiful. My pond is between 1/4 and 1/2 acre this was perfect size. The kids want to swim in the pond now because it’s pretty. Great quality for the money it was definitely worth it.

Kills Algae quickly

Don’t have instructions how much to use I have used this before it is good for cleaning your pool but I don’t thank you get your money worth but it is a good product

It is exactly what you need for your ponds
