Would Recommend[This review was collected as part of a promotion.] Before I found this algea guard I was having to scrub the walls of our pool several times a week to keep algea from building up. Since I have added this algea guard to my pool care routine, I find myself scrubbing much less and my pool staying cleaner longer. Totally reccomended for anyone with a pool

Great freatures!
Would Recommend[This review was collected as part of a promotion.] Excellent product! It works very well. The pool in my house was green and brown due to lack of cleanliness of my husband and children. I got up early on the weekend, started cleaning and brushing the edges, walls and bottom of the pool. I added the product to the pool water and the water was clean the next day.

Clear Water at last!
Would Recommend[This review was collected as part of a promotion.] I seriously had no idea how much algae was floating around my pool until I used this. I thought it was fairly clean! It wasn't. I have a pool cleaner come once a week, and I thought the pool looked just fine. but my husband was insistent that it could look better. He used this before our 4th of July party, and it really did the trick. The water looks AMAZING! Thank you!

Good product
Would Recommend[This review was collected as part of a promotion.] Got some of this because we were having some green algae issues with our inground pool. Put about 6 ounces of this in the pool and in a couple days the water was back to shining. Would definitely recommend this product to anyone that is trying to eliminate and control green algae.

works very quickly
Would Recommend[This review was collected as part of a promotion.] We have a horrible algae problem in our pool, I think possibly due to the content of our well water. anyway, after trying a few other products (all were other brands) decided to try this one. Added it in and the green was gone overnight. Did have small issue with foam (says non foaming) but it was gone in a day and I might have added a bit too much the first time, as it has not happened again. I did have pool filter running when I added it,...

Great product
Would Recommend[This review was collected as part of a promotion.] Even though the shipping was soooo slow, the product is ok and it lasts a lot! It works good and I have not to complaint! I think the brand is very reliable as well. I would buy it again! The effect is almost at the same time you apply it

Really solid product
Would Recommend[This review was collected as part of a promotion.] We have had issues with over chemicaling our pool and this has been a great solution. It isn’t over bearing and prevents a lot of the green algae that seems to build up around the edges. Even when we think we’ve done a great job cleaning there would always been a spot or two. This guards against the algae and really keeps the pool looking fresh.

Easy to use
Would Recommend[This review was collected as part of a promotion.] The HTH Super Algae Guard, 32 oz is a fast acting solution that prevents algae. I was really surprised at how fast it worked and that there was no foaming after using it. The kids were also happy to be back in the pool..

Worst product ever
Would Not RecommendBought Algae guard non foaming and it does know how do you get rid of all this foam in the pool.

Horrible foam I can’t get rid of!!
Would Not RecommendBought this for algae in water feature pool..... I used the recommended amount in the evening...immediately began foaming (bottle states “non-foaming, quick acting”).....next morning, still has a foam-top that won’t go away! Can’t really see if it’s working on algae with all the foam!!

Terrible Foam. Label clearly states "Non-Foaming"
Would Not RecommendI purchased for a non-foaming algae guard as described on the container.
From hthpools.com
Awful
Would Not RecommendI have used the stuff that you only add once a year and it always worked great. This year I used this 60 and was told to add it weekly. This new product meshed with my pool water in the worst way. It says non foaming but it has created a bubble bath in my pool. Also the smell from this product makes me nauseous when in the pool. I'll never use this again.

Absolutely Amazing!!!
Would RecommendOur pool water looked like baby diarrhea or dark green swamp water, I could have cried. For weeks I was spending several times daily cleaning, sweeping, removing debris, and cleansing our filter by spraying it off with our hose. Nothing I was doing was working, I was tempted to drain our pool and just be done with it for the season. I happened to read the label of this product and thought it was worth trying, price was right so I really didn't have anything to lose. Product smells amazing! ...

Keeps the Algae Away
Would Recommend[This review was collected as part of a promotion.] We used the algae guard for the first time this year to keep the water clean and crystal clear. So far, it works great! There hasn't been signs of algae yet and have been staying on top of up-keeping it. So far, I say it will definitely keep the pool ready for swimming. I am happy with the results so far.
