    • Amazing product!

This product is amazing! My pool has never been this blue. We recently had a tropical storm come through our area dumping massive amounts of rain which caused an ugly mustard algae bloom. I must have dumped 5 gallons of chlorine into it over the course of a week and the algae wouldn't budge - it actually got worse. In desperation, I ordered this product. We put 14 fluid ounces in immediately. It lightened up the pool, but there was still some algae present, so we added the rest of the 32 ounce bottle the next day. Overnight the algae disappeared and the pool got even bluer as time went on.There is currently no chlorine left in the pool and it is still blue with no signs of algae. I put the last of the product in on Monday and today is Friday. This product works miracles. I wish I had known about it sooner as I could have saved myself a ton of money and grief. Other users have mentioned having trouble with foam. We have had zero foam. The only thing I can think is maybe the product is interacting with other chemicals present in their water, because we have had no foam and we used the whole bottle. Excellent product. I highly recommend for stubborn algae problems. ... show more

    • Works well!
Style: Ultra Algaecide
I have little to say about this other than it works great. Prior to this, I was heating my 25,000 gallon pool to 90F (we like big baths and we cannot lie) and I had a severe algae problem on the shaded side of my pool. I would have to brush the walls every 2 days and ended up shocking frequently. Since I added this to the water - it's a copper-based solution, and copper is known to disrupt microbiological activity; it's a disinfectant in that way - I have never since had to scrub algae off a wall. It was a night and day difference. I will put this on my routine purchase list. I'll try two applications next season and report back if it doesn't keep the algae away. ... show more

    • HTH are Good Products!
Style: Ultra Algaecide
A dose of 6oz every week in a pail of water has prevented algae in my 17K gallon pool all summer and we live in Florida where Algae can grow easily! Definitely cheaper than in the pool stores.

    • Best Algae Guard . 3 month coverage
Style: Ultra Algaecide
I have used HTH products before. I tried a few other name brands that went on sale. I have had over 5 homes with pools. The constant adding chemicals and monitoring is a nightmare during hot months. This Algae Guard from HTH is amazing. 90+ days and no need of adding any algae or clarifier. Chlorine tablets only . Water Clarity and PH are perfect. I thought a little pricy at first but it actually last 3 months. Great Product ... show more

    • HTH 67289, not HTH 67084. The only algaecide that works for us in HOT South Carolina
Style: Ultra Algaecide
Review Image by Michael R. Stiteler Michael R. Stiteler
NOTE: Amazon lumps reviews of several products together. HTH 67289, not HTH 67084 is what actually works. I would not recommend HTH 67084. Lots of money and poor performance. HTH 67289 is what works. Started working in minutes and getting better by the hour. We spent a lot of money on the other algaecides by the same company and other companies. None of them worked. Our pool would be green as ever within a week. We used a lot of chlorine far more than we should have. This product works. ... show more

    • Works to kill all types of algae in your pool, but foams for a few days.
Style: Advanced Algaecide
If you are battling algae, especially mustard algae which is so hard to get rid of, this product will work for you. It doesn't foam a lot, unless you overapply, but it will cause a slight foam when people are playing in the water, up to three days later. I'm not sure if this was the cause, but one of my grandchildren (three year old who puts water in her mouth and occassionally drinks the pool water) got a low grade fever and threw up a few times after swimming in the pool three days after I applied this product to kill algae. It could be a coincidence, but maybe take precautions to prevent getting water in the mouth for a week following the application. ... show more
