HTH Algae Guard Advanced — Liquid, 28 fl oz — Pool Algaecide Compatible with All Pool Types

This is the best Algae cleaner for my pool. We travel quite a bit for work and I'm always concerned about the pool with algae on the walls. I don't have to worry about that with this product. You just have to use the right amount for your pool size to prevent it getting cloudy but it works!!!

We emptied our pool and refilled it this year, unfortunately our filter needed to be replaces so the water sat with only a chlorine pool floater for about 4 days so it turned green from the algae. I put about 6 ounces in the pool filter and allowed it to recirculate for about 5 minutes before switching it to filter. Our water was crystal clear within 24 hours. Amazing!

This is a good product for my non-filtered backyard water feature. A small teaspoon every three days seems to keep my algae levels and blooms under control. I've used this product for about a year in conjunction with HTH Bromine tablets and my pond water stays clear. No evidence of any harm to my fauna users, day or night.

I've purchased before and always satisfied. Cleared up green algae quickly where pool maintenance chemicals did not.

I was a little bit skeptical because of the size of the bottle, but it got rid of my pool algae in 24 hours.

Easy to add to my salt water pool. Just don't overdue it. Read the label and it will make your pool opening in the summer perfect!

It has been a very warm February and early March here in Central Texas. The pool had developed very early. I used the algicide and it began working on my trouble spots right away.

This gets the green out of my pool

I found this product easy to use. I could scatter it around the pool efficiently. It definitely helped clean up the water.

Did not clear my pool had to get a different algaecide
