Excellent product!

Would Recommend

[This review was collected as part of a promotion.] This product is excellent! I have an 8,000 gallon above ground pool. I used only 3 fl. oz. a week, and I have never had an algae problem or problem with cloudy water. The directions are easy to use, and it even has a measuring scale on the side to show how much liquid to use. So helpful!! I would definitely recommend this product to others.

The best non-copper formula

Would Recommend

[This review was collected as part of a promotion.]  I was having a horrible algae bloom and nothing was working. I had been putting other copper formulas of algeside in the pool and checking all the levels making sure the PH was right and the chlorine was low. I tried this Advanced version, which is non-copper based and put the recommended dose for the initial use in and the next day I saw results. I usually stick with Copper type formulas like the Ultra version, but I have to say that stuff is...

Algae Guard Advanced

Would Recommend

[This review was collected as part of a promotion.] The bottle states that you can swim 15 minutes after using the product. However, took quite a while to skim the foam out of the pool. I definitely would not call this a non-foaming product. Other than that, it did eliminate the algae I had in my pool and it seems to be keeping it away as well. The directions say to use it every 3-5 days for maintenance. However, with the amount of foam it created, I definitely won't be using it that often.

Works!

Would Recommend

[This review was collected as part of a promotion.] The HTH works faster and better than other brands I’ve used in the past. If you follow directions exactly your algae will clear in 24 hours ready to vacuum. I like that you can use as a preventative algae maintenance especially for busy people who can’t check the Pool every day. This will be a staple in my pool shed! Highly recommend

More time to swim

Would Recommend

[This review was collected as part of a promotion.] As a second-year pool owner, I've learned regular monitoring, maintenance, and having what you need on hand will keep a pool clear. It amazes me how quickly things go wrong when you don't. With HTH algae guard added weekly. There is less need to over-chlorinate my water. More time to swim in a safer pool.

Would Recommend

[This review was collected as part of a promotion.] If you own a pool you know these humid conditions wreak havoc on your water. We have bad algae problems here when it’s like this. Since I’ve been adding this algae guard in maintenance doses, we haven’t had an algae problem. Recommended to my neighbor as well and he’s thankful!

Great for keep pool algae free

Would Recommend

[This review was collected as part of a promotion.] This HTH® Pool Care Algae Guard Advanced is great for getting the pool back to good, and keeping it that way. I had a problem last summer with green algae in my pool. I read up and this was recommended, along with brushing it more often. I started adding this weekly and brushing more often. It’s easy to use, and I just add it to the water, run the filter and it’s good to go. The water is crystal clear and my family is super happy.

Amazing Job!

Would Recommend

[This review was collected as part of a promotion.] I wish I took a before pic so posting the after won't make sense. The HTH pool care algae was a miracle worker. Our pool was a gross shade of green, after reading the directions and adding in the amount needed our pool is now a lovely shade of clear blue. There was no weird after smell either.
