What Customers Are Saying
The product is generally effective at controlling and preventing algae growth, quickly clearing up various types of algae and leaving the pool water clear. It is easy to use and a little goes a long way. The product works well even in conditions that promote algae growth. However, some customers had mixed experiences, with a few finding it created excessive foam or didn't fully eliminate their algae issues. Overall, the majority of reviews indicate the product is a reliable and convenient solution for maintaining a clean, algae-free pool.

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.

no green to be seen
Would Recommend[This review was collected as part of a promotion.] I've been using this in the baby pool so that it doesn't have to be emptied out as often as usual. The water in my town, if not treated, will turn green in as little as two days. The super algae guard is helping me save water and save money and the kids have clean wading pools to play in.

Works great!
Would Recommend[This review was collected as part of a promotion.] We were late opening our pool this year because of the crazy weather we had this year... I don’t know if that contributed to th green water or if my husband just didn’t winterize the pool properly when we closed it up last year... anyway, this stuff cleared up the water really well! Follow the directions and just use the amount specified for how many gallons you have. It bubbled up a little but once they cleared, the water wasn’t green anymor...

Keeps it clean
Would Recommend[This review was collected as part of a promotion.] Received this product to test out in my pool. It came just in time since it is pool season. I had not used this product before this time. Really did not know to much about alge guard. I do however know how fast it can grown in the pool. This product did make a huge difference in the time it kept it away.

Works Beautifully
Would Recommend[This review was collected as part of a promotion.] One of the worst things about dealing with a pool is controlling algae growth. Yuck -- it mucks up the water, the pool bottom and makes you just not want to go in. This product worked like a charm and did it quickly and simply. Plus, you don't have to keep everyone out after adding the chemical. I highly recommend this product.

Great product!
Would Recommend[This review was collected as part of a promotion.] Super algae guard 60 worked really great on my pool! It worked way better than the other algae products I have used! I would highly recommend this product to others! The algae cleared up quickly! Now we're ready for summer!

Good product!
Would Recommend[This review was collected as part of a promotion.] So this product does exactly what it says it’s supposed to do. It got rid of my algae and it did it pretty fast! I love how blue and clean my water looks. The only downfall to this product is that you have to be consistent, because if you aren’t you will start noticing the algae come back. So stay on top of it and you’ll have no problems!!

Works great
Would Recommend[This review was collected as part of a promotion.] I bought this product super algae guard 60 recently and absolutely love it! I've been having a bit of a problem with algae lately and my previous product didn't seem to be working as good as it should have. So by trying this new algae guard and having it remove what the other brand wouldn't...I would say that I am extremely happy with it. It actually took all the Algae away very fast. Now the upkeep is a breeze.

Great product f
Would Recommend[This review was collected as part of a promotion.] Great and easy to use. We just got our pool up and ready for summer and this was a great choice of product to use. Didn't take long before the pool was ready to go. Would definitely recommend to anyone!

This is always my go to product
Would Recommend[This review was collected as part of a promotion.] I've always bought HTH Super Algae Guard for my above ground pool as I know it just works. I don't try the other brands because they never give me the results that HTH does. This always keeps our Algae at bay along with salt chlorinating machine and chlorinating granules. Works great even with high heat summers or if I am gone a few days away on vacation.

Love this
Would Recommend[This review was collected as part of a promotion.] I have been using this since last year and I’m glad to use it again this year. When we set up our pool and when the water is starting to look a little dirty we pour some of this liquid to avoid the water from turning green. Definitely recommend
