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.

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.
