Ratings & Reviews for HTH 32-oz Pool Algae Prevention

Didn't work for me

[This review was collected as part of a promotion.] We have a hot tub that has turned to the green side. I added the required amount and ran the hot tub but the next day I saw no difference. I'm not the best at taking care of the spa. All these chemicals intimidate me. I'm not sure what I did wrong. The color of the chemical is strange. It's an electric blue.

Works for 3 months and is so easy to use!

[This review was collected as part of a promotion.] I have a 10,000 gallon pool and this 16oz product treats up to 10,000 gallons, so that’s perfect. I put the product In my pool according to instructions in different spots and left the pump running for a few hours. I have a green and yellow type algae in my pool, and this product went to work immediately. I love the fact that this product continuously controls algae for 3 months! Really helpful product and worth the price.

Excellent product

[This review was collected as part of a promotion.] This HTH Algae Guard is excellent! I know sometimes you can feel hopeless when your pool turns green and cloudy and you can feel super discouraged and like it will be a lot of work. The algae guard is so amazing that it literally starts working instantly. It starts fighting the algae immediately and you can see it start to work. It only takes a few hours before the pool is crystal clear and it stays that way for a while before you have to treat...

The Best

[This review was collected as part of a promotion.] The high temperatures and heavy rain in Georgia makes my pool water very dingy. After using the test strips l used the HTH POOL CARE ALGAE GUARD ULTRA to help balance my water parameters. It worked well, the pool was restored to a good sanitizied level. The product workedquickly, had no fowl odor and the instructions were easy to follow. I will continue to use this product as a preventative algaecide.

Thank you for the free full size product in exchange for my honest review ...

No more green!

works like a dream

[This review was collected as part of a promotion.] This algae gard is just what we needed for our pool. We had a little problem at the beginning of the summer keeping our pool Chrystal clear and the ph levels right. We got this, tried it in our pool that was turning slightly green and it disapated the cloudy green making it clear again. I'd definitely recommend this to others. It worked great.

Quality product

[This review was collected as part of a promotion.] So the HTH algae guard is definitely making a difference in the cleanliness of my pool. I use HTH shock first then the next day I add the algae guard and the sides and bottom of the pool clean up quickly.

Works well - just follow directions closely

[This review was collected as part of a promotion.] So I was on vacation and my pump quit working during a storm. So of course I had algae and my pool was green once we returned. I used HTH to get rid of the algae and along with the salt pump (salt water pool) and shock - I was able to get my pool back to swim able shape within 3 days - which is awesome. I have used HTH products but never before the long acting algae killer - so I'm hoping for some relief longterm! One week so far and it is stil...

No algae, does the job.

[This review was collected as part of a promotion.] We've been having exceptionally warm weather, and this has caused a new algae growth problem for us. This has helped address it, as it was new to us, and it has kept the algae gremlins at bay. I appreciate the swim immediately aspects to the product, as I worry it is too harsh to come into contact with. It has not created any skin or other concerns, and has been wonderful to have the algae under control. I'll continue to use it throug...

Works like it should

[This review was collected as part of a promotion.] This is a great product. Well worth the money it only takes a few ounces per 10,000 gallons. This is one of the best algaecides I have ever used. It works great as a preventative and to clear up algae that is already growing.

Great packaging

[This review was collected as part of a promotion.] I like how they have packaged these bottles. The other competitor has bottles that are hard to grab and hold. HTH has been around as long as I have had a pool and I'm sure long before that. Lol. I think they got it figured it out.

No algae!

[This review was collected as part of a promotion.] I used the product with the hopes of cutting down the amount of times I'd have to add Algae Guard to my pool. So far, so good! My pool has been free of algae for weeks now and it only took the one treatment. My old product had to be added weekly; god help you if you fogot! Highly recommended!

Brand you can trust

[This review was collected as part of a promotion.] This HTH pool care algea guard ultra did an amazing job keeping the water clear and algea free. Living in the south east, the heat and humidity will turn the water bad right away and this really helped keep the algea under control.

Will kill algae

[This review was collected as part of a promotion.]  I tend to sick with the copper based algesides because I know they work, during my last huge Algae bloom I tried everything else to get rid of it. The Ultra algeside is a copper based algeside and it's long lasting to prevent more blooms overtaking the pool. I didn't have to use nearly as much of the product as I thought, but my pool is rather large and it does require more product then most other algeside. It also says non foaming formula but...

Works great

[This review was collected as part of a promotion.] After trying this for the first time in my spa tub, I can really see a difference in the water. It is a lot cleaner for a lot longer. I like that it doesn't foam up and make a mess. Very Nice. I am very happy with it.

Foamed

[This review was collected as part of a promotion.] Pros: does clean and clear away algae from pool. Safe you swim in afterwards. Cons: due to the buildup, this left a layer of foam on the top. The next day the pool was clean and ready for swimming. So I wouldn’t swim in same day, especially if you had an aggressive algae problem.

Guard my pool from algae.

[This review was collected as part of a promotion.] HTH Pool Care Algae Guard Ultra is a great product I used to prevent algae from forming in these hot summer days.With water temperate being 85,and the sun beating down on the water,is a great combo for algae to start growing.I used this product that will last up to 3 months to prevent algae growth. Can also swim 15 minutes after adding to pool.Keep the pumping running for several hours.

Algae Guard

[This review was collected as part of a promotion.] I bought some HTH pool care Algae Guard to prevent Algae and it works . The directions are easy to follow and measure right amount to the gallon pool size you have and you can swim right away to. This is some real good stuff.

Maximum protection against algae

[This review was collected as part of a promotion.] This HTH® Pool Care Algae Guard Ultra is the maximum guard and protection against algae in your pool. This is the long lasting formula that lasts up to 3 months. While I do like using this, I was already using another formula in my pool, so I started using this in my parents pool. I like how I can add this to their pool, as I am the one that maintains their pool, and I don’t have to add it every week. This works long term. It has a tendency to ...
