I tend to use this more frequently than suggested, I had half a bottle every 6 weeks instead of one bottle every 3 months. Yes I know that's the same amount over a 3 month. But when I added it all at once to start using it, it didn't last the full 3 months. Live in a high algae area.

Great product and I use nothing else for my 3 month treatment. Great seller that responded immediately on a slight issue with shipping box. I will be a return customer.

Wow! What a fantastic product. Fought algae growth for years. Whenever the chlorine level would drop, algae would start appearing on pool walls. Since adding this product haven't had any indication of algae. Pool sparkles now and it seems like my chlorine lasts longer. Highly recommended.

I bought this for black algae that other chemicals didn’t kill. I will say scrubbing is a B1tch! But the algae didn’t return so it works as advertised. I do think the price is a little steep. Additionally it would have been helpful if the instructions or website or Amazon description said how long before you can re enter the pool after application. You will wonder this yourself because the water stays blue for several days and makes you wonder if it’s safe for eyes and skin, my wife and daughters only cared about messing up the color of their new swimsuit, guess it’s true everyone has their own priorities.

We purchase this regularly for our above ground pool, going on six years now. We were using Cl--x Algaecide Prevention. Despite following directions and regular weekly use, our pool still had algae issues. Not with this stuff. SeaKlear works great at prevention and we really like that each does lasts for 90 days vice weekly doses with others. A bit more money but well worth the cost over the long run. We're so glad we found this one. Highly recommend.
