No More Black Algae! Salt Water Pool
I have a salt water pool in the desert. Due to 110+ summer temps and blazing sun, black algae sometimes shows up if I forget to increase salt cell output. Having a PebbleTec surface makes getting rid of it even harder. This is hands down the single best pool product I've ever purchased. It even got rid of the few spots I missed brushing! Im not sure if a water clarifying agent is part of the formula, but my water someone becomes even clearer when I use this. Highly recommend!

This stuff WORKS!
At first I was skeptical but hopeful on this algaecide. I had read some less than ideal reviews, but I bought it anyway, hoping it would work. Turns out that it turned my dark green pool into a nice bright blue in TWO DAYS. I added the recommended amount according to the bottle, in conjunction with two pounds of shock treatment. All the algae is now dead or dying, and I couldn't be happier. I was afraid I was going to have to drain the pool for a deep scrub or a resurface, but now I don't have to. The water didn't clarify much, but I have another product for that to test next. It did definitely clean the water up a bunch though. This 4 pack is a fantastic deal. My pool looks good again and well enough to enjoy soon.

Works well and cheaper option than others
Price was very reasonable and cleared up an algea bloom that popped up when I let my chlorine level get too low. Cheaper than other options. I will buy more because of my experience

Water Clarity is Right On.
Doheny products all seem to be of very good quality at a fair price. This is no exception. Everyone has to deal with algae in Florida because their pool has to be continuously maintained for basically 10 months out of 12. I followed the instructions. No need to reapply for 3 months now. Pool water has stayed clear.

Great product
I’m a maintenance worker- This is an excellent product to treat visible black algae But also very good as a maintenance deterrent against future black algae

From green to clean!
This is the real deal! Turn your pool from green to clean in about a week. Ours was neglected when we moved in and Doheny's Syper Algaecide cleaned it right up. When chlorine alone won't work, use this algae killer!

Great product to have on hand through the entire year.
This product is excellent. It turned the murky water clear in the space of 24-36 hours killing the algae. My pool needed two doses only because it was an extreme case. Very satisfied.
