Great item and pkged securely sealed

[This review was collected as part of a promotion.] This just works. Period. Pour some in several spots around your pool with the pump running and you'll be algae-free for three months. I've tried several other products but nothing works like HTH Ultimate Algae Guard. Highly-recommend.

[This review was collected as part of a promotion.] I have a small above ground pool, and we always would end up with that slippery floored algae feeling, cloudy water, and fuzzy walls....then we got this amazing product! Have an algae problem? Get some of this stuff and you won't

[This review was collected as part of a promotion.] When this came in the mail I was surprised to see it as I forgot I ordered it. When added to the pool it does a great job of ridding any algae that is inside it. I would highly recommend it to anyone looking to get their swimming pool bright and clean immediately.

[This review was collected as part of a promotion.] Ultimate Algae is by far the best product I’ve used for my pool Algae blooms. Every year we have fought the blooms with little success, until we started using this product which keep it in check! I highly recommend if you have a hard time keeping algae in control.

[This review was collected as part of a promotion.] you can actually swim 15 minutes after applying this to your pool. that is a game changer for us. it seems to last longer than i'm used to also. it appears to work on all different types of algae so you don't have to be specific in what you purchase. this is a great brand that i trust for my pool needs.

[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!

[This review was collected as part of a promotion.] This is our 2nd time to set up ground up pool. First time we didn't use algae guard. This time we got this and we can maintain the pool very clean! I can let my kids play in the pool everyday and don't be afraid they get sick! So far very good product to use!

[This review was collected as part of a promotion.] The thing about algaecide that used to bug me was the foam. I'm glad to have found Ultimate Algae Guard, because I can add it and don't have to deal with the questions about that foam all over the pool.

[This review was collected as part of a promotion.] When I decided to try this liquid it was because my pool was starting to have a little bit of Algae but it was very minimal, after putting it according to the instructions the water turned completely green !!! it was horrible!!! but I let the chemical work, it takes about 5 days to turn blue, it works too slow, not like it says on the boat ... after that I took a water sample and took it to a specialized pool place and it turned out it was high in metal and other things, I had to do Other treatment for my pool and now the water is completely crystal clear.
