We purchased this algae guard and have had excellent results for our above ground pool this summer. With just a little splash every couple of weeks, we have noticed all algae has disappeared from our pool. We will continue to purchase!

5.0 out of 5 stars Works to kill all types of algae in your pool, but foams for a few days.
Reviewed in the United States on July 4, 2024
If you are battling algae, especially mustard algae which is so hard to get rid of, this product will work for you. It doesn't foam a lot, unless you overapply, but it will cause a slight foam when people are playing in the water, up to three days later. I'm not sure if this was the cause, but one of my grandchildren (three year old who puts water in her mouth and occassionally drinks the pool water) got a low grade fever and threw up a few times after swimming in the pool three days after I applied this product to kill algae. It could be a coincidence, but maybe take precautions to prevent getting water in the mouth for a week following the application.

Reviewed in the United States on July 1, 2024
This stuff works very well. We haven't had any algae now for a month. We used to have light green algae in our pool about every three days. This has eliminated having to vacuum the pool as often.

3.0 out of 5 stars It probably works but foams a lot
Reviewed in the United States on July 7, 2024
I used multiple
Things to get the green out and balanced water. Not sure if this product alone helped but all the green is gone. What’s not gone is the foam for next 2 days or so. I don’t want to get in this water.
Also
I didn’t vacuum but the robot cleaner got most out.
