There are better

Would Not Recommend

[This review was collected as part of a promotion.] This product didn't work well on my pool. You will need to use a lot more product then other brands might require, making you spend even more than you should. I wouldn't purchase again. Only reason I am giving it a 3 star is due to the budget friendly and easy accessibility in stores.

A Must Have for garden fountains

Would Recommend

[This review was collected as part of a promotion.] I have been using HTH's Super Algae Guard exclusively for my garden fountain over the past 2 years. It has been the only additive I've found that keeps the water crystal clear. Anyone with an outdoor garden fountain knows how tedious it can be other than draining and refilling it all together. Instead of draining the fountain as recommended every month, I can go by 6 months with clear water by just adding a few ounces.

keeps my pool sparkling clear!

Would Recommend

[This review was collected as part of a promotion.] I've been using HTH Super Algae Guard for the past month. Yellow algae seems to be the main issue that my in-ground cement pool has. Following the directions for the initial dose for a 10,000 gal pool, I used 4 oz. Then I have been using 1 oz every 3-5 days as maintenance. I also regularly brush and vacuum to keep the pool as clean as possible. Living in NE Florida, my pool is the prefect escape from our record heat, and this Super Algae ...

Love this product!

Would Recommend

[This review was collected as part of a promotion.] We used this in our backyard pond and has been doing what it says it will do. Even though we have the pump running all the time we still get some algae buildup so this has been great. We removed the fish while using it to get it clean and they may be actually thankful for this. Well at least we are because it made a great improvement.

Clear pool!

Would Recommend

[This review was collected as part of a promotion.] My pool was starting to get green algae on the bottom due to having some pool pump issues. My husband added the Algae Guard and it cleared right up!! Nothing is worse than wanting to swim on a HOT summer’s day and not feeling comfortable due to the gross looking algae. I would differently recommend this product.

Works, but foam left behind can be a pain.

Would Recommend

[This review was collected as part of a promotion.] Had a bad algae problem in our pool, and this helped tremendously combined with a shock treatment. After roughly 34 hours, the pool went from a dark muddy green to crystal blue. In honesty, I believe the algae guard alone sped up the process. Taking off a star because the algae guard left behind a little foaming issue that took quite a while to dissipate. To explain, it was a mild, thin layer of foam in spaces.

Excellent algae cleaner

Would Recommend

[This review was collected as part of a promotion.] Our pool was full of algae after our pump broke down. We were able to get the algae under control within a week. We have since used this product weekly so the algae does not return. We are happy we can use our pool again in such a small amount of time.

Helped get rid of the green!

Would Recommend

[This review was collected as part of a promotion.] We have an issue with algae buildup on our pool tile. Adding it to the pool without having to scrub was really convenient. This plus shocking our pool more regularly has left the pool feeling much more clean this summer. Good product!

Algae be gone!

Would Recommend

[This review was collected as part of a promotion.] I live in Florida which means that during the summer, I am living in my backyard pool. The issues is with continuing use, there is a quick build up of algae in the water. This product quickly helps remove any algae in the water and gets rid of that slimy algae feeling. And it’s affordable too, can’t beat that!

Very efficient

Would Recommend

[This review was collected as part of a promotion.] Due to a wild variety of unique and unfortunate and unforseen events we have battled the little "yellow" enemy in our pool this year. Yes our pool's nemesis known as algae. Not exactly sure as to all the reasons why this season has been so tough to get the pool clean and clear. What I do know for certain is that using this algae treatment was a "one and done." It's great to know that this is product that works as intended. The first time!
