Name says it all

This product is being used in my pool now, and having water checked have no problems at all. Happy with results so far and expect it to continue to do the job for the rest of the summer. Which will make my summer more enjoyable.

Awesome Algaecide for our pool needs to keep us up

The Clorox Algaecide works great in our back yard pool. It is affordable and effective in beating back algae. It has helped us to keep our pool swimming ready for these warm springtime swims and the upcoming hot summer days.

This Algaecide Helped!

I’ve been a self-taught pool owner for 15+ years and I always have trouble keeping my pool clean. When I recently found myself with a green pool (again – ugh), I used the Clorox Awesome Algaecide (along with shock) and within a couple of days my pool started clearing up. I like the fact that you can see the product go into the pool at first. I will be using this some more–hopefully as a maintenance product now.

Great to fight off green algae!

Didn’t properly close our pool for the winter months, so we had a pretty good green algae situation throughout our pool. This helped combat the issue and cleared up the pool very well. I definitely recommend this product!

A must have for pool owners

I have been using this product for years now! It is a must have product when living in Florida! Between the heat and the rain it can sometimes be difficult to maintain our pool. Weekly treatments in addition to the phosphate remover keep my pool clear.

A must have to keep the slime away

I add a little of this to my pool every week. Guaranteed to keep algae away. Along with using shock and keeping my chemicals stable, this works 100%. I’ve never felt my pool feel even slightly slimy. This is a must to have added to your pool.

Perfect Water

Living in south Florida, it’s a daily battle with the algae in this heat. Follow the label and use it monthly to maintain a perfectly clear pool. Will continue to purchase and use to keep the pool looking it’s best.

AWAY WITH THE GREEN

Living in Florida we periodically develop an algae problem in our water. I started using the Clorox Green Algae Eliminator. I use it weekly in our pool now. Approximately 1.5-2 ounces. Have not had a algae issue since.

Green Water no more!

This spring was a warm one, and the pool water got away from me. You guessed it green water! Awesome Algaecide took care of the problem in the twinkling of an eye. I added shock to the pool, ran the pump for an hour, then added 16 ounces of Awesome Algaecide, continued running the pump for 24 hours. I’ve got to say, it was a great pleasure to wake up to my pool being clear, and I could see to bottom of my blue liner. I’m going to use as a preventative once a week.

Great Product That Works Very Well

Works incredibly well for us. We have a shallower plaster pool and live in the Houston area, so hot and humid. We use this once a week during the peak warmer/hot months on Wednesday’s, and do pool shocks on Monday’s. The schedule works well for us, and keeps the pool nice and clear.

A Must Have

I love Clorox Products. They are very easy to use and works wonders on my above ground pool! Using the test strips help make the measurements a better easy going process. Highly recommend for any pool

New Algaecide

I haven’t tried this particular line of algaecides before this. I started this past week to get ready to open for the season and it seemed to help clear up some mildly cloudy water. This has some slightly different portion sizes and time frames than others that I have used, so that will be interesting to see how it performs.

Perfect for any algae needs!!

After winterizing my pool, it was a very easy to clear up the algae that had accumulated due to non use. Easy to follow guidelines and the product worked amazing! No harsh smell and cleared up very quickly!

Bye Bye Algae!

Love this product. After it rains, I add this product to the pool. Last year for some reason our pool would get algae after raining (never happened in past years). It would take a couple of days to clear up. I got this product and added it after a early morning rain shower. I was happy it did not take days to fix. This product is now my go to for algae.

Easy to use. Great for preventative maintenance.

Product works great. Add a little to the pool each week as part of my routine and never have any algae. The directions are easy to follow and there is no guessing how much product to add based on the size of my pool.

Takes the Algae away

This Algaecide lives up to the Clorox name. Super easy to use. It amazed me at how quickly it worked for my spring pool opening. I had more algae than normal this year, but with Clorox Algaecide and shock we are back to crystal clear water. I recommend to anyone with a pool.

Works Great on Mustard Algae

I usually get Mustard Algae, a few times a year. Clorox Pool Xtra Blue Algaecide is always what I use, kills all of the algae within a couple of days. I’ve tried other brands but this one is the best by far!!

Great Algaecide

The Clorox Algaecide really helps keep my pool algae free. I usually try adding this weekly to my pool but when the temps are pretty hot and it’s been raining my pool seems to start getting algae on the bottom. I will add and extra amount of algaecide to my pool and it always gets rid of the algae. Great product

Great product for algae treatment and maintenance

This algaecide works well to clear up any outbreak that I’ve had in a few days in combination with proper brushing. I also use it for weekly maintenance to ensure I won’t have any major algae blooms. I recommend monitoring mineral levels, as this is copper based and using too much could cause consequences.

Works like a charm

I was very surprised when I walked outside to find my above ground swimming pool looking like a swamp. This was my first experience with algae. I followed the directions on the bottle and by the next day the pool was back to it’s beautiful clear self.

Early algae

Great product that had a huge impact on the pool even very early in the season. Had some early algae due to a low chlorine level and this product cleared up the issue very defectively. I’m sure I’ll be using it through the summer as maintenance.

Great product, highly recommend

Works great, I use it whenever I need it and gets rid of my problem quickly! I would recommend this product for any above ground pool. I have used others and they left a soapy film in my pool, but not this one!

Great product

Great product. I used this product to eliminate green algae off of the walls of my 22,000 gallon inground pool. After scrubbing pool walls with a brush and then applying the product, my pool water was clear and blue once again.

Bye bye algae

Nobody likes to get algae. Using this product on regular basis will help avoid that. But especially in the Arizona heat, getting behind can happen. This product really helps keep you pool looking great and the algae away!

Great product

The Algaecide works well, but I find that it takes more than the recommended dose – much more. The particulars could be specific to my pool. But, as far as working – this definitely works! It is cloudy at first, but then leaves a cleaner pool behind!

Algaecide

I added this to my pool at the recommended rate to kill green algae for my seasonal startup. There was a noticeable difference in the amount of algae after 2 days. All I need to is a quick brush and it should be good to go

Excellent Algaecide

I use this as part of my weekly pool maintenance and it has worked perfectly. I have had only a few minor mustard algae spots that show from time to time in the summer, after a rain storm. I simply brush them and use the weekly dose. Has worked great.

Great results

I have had great results with Clorox algae eliminator. This is my go to product after a good rain to help any algae issues that might arise. I have found if I use the recommended weekly dose after a heavy rain I have not have any issues with the pool turning green.

Perfect

Just what it says. Perfect algicide to keep algae down. I use it during the summer to help because my chlorine goes so fast in the summer, sometimes I can not keep up. This helps it from getting out of control.

Great product to handle tough messes

Maintained my pool by myself for the first time last year. Ended up dealing with a large green algae outbreak. Used a bottle of this stuff and the algae cleared out in a weeks time. Great for outbreaks or weekly maintenance.

The One to Buy

Absolutely love this product! It works fast, works easily, and works for a long time. No other product compares. Doesn’t leave any smell nor harshness to swimmers skin when used. Have used a number of times against green algae and the only one I trust!
