## Customer Reviews

### ⭐⭐⭐⭐⭐ Best price for polyquat 60 I have found
*by M***R on May 31, 2013*

All polyquat 60 is made by the same manufacturer, just bottled by different companies. So shop for the best price - and this Kem-tek is the best price I've found. It works and is cost-effective. No, there is no clear strip down the side of the bottle for "measuring" - I use a plastic measuring cup and would never downgrade this product for that reason. If the bottle has 32 ounces in it and you use 2 cups ... Just do some basic math in return for saving a major amount of money on this brand. Polyquat 60 is the only algaecide that works or is worth spending money on. I live by saltwater and have a pond on my property as well and algae blowing in and being dropped by seabirds was a continual problem that this product has finally enabled me to get a handle on.Some people have said it did not work for them. I'm not criticizing anyone, but I have found that it is important to follow exactly the instructions for using this product. If you have a large algae bloom in your pool, you must shock the bejeebers out of it before you use any algaecide. This product's directions say as much (OK, it doesn't say "bejeebers.") I had a big algae problem two seasons ago and employed the "Bejeebers Shocking Treatment," vacuumed out the dead algae (looks like grayish silt on the bottom), then used this product according to the label instructions, then vacuumed again (the label says to do this). Then I used this product in the "maintenance" dose the rest of the season. I have always had an algae problem toward the end of the season (mustard algae, yuck) but after I started using this product according to the instructions, I have now had two seasons with no algae bloom at the end of the summer. When the algae starts to rear its ugly head in late August, it's because I tend to slack off on shocking and algaecide as the summer wears on, so mea culpa. However, I have avoided algae blooms since using this product.This past Spring, this product again came to the rescue because my winter cover developed several holes (birds and ducks pecking at it) and when I took the cover off to open the pool, it literally looked like split pea soup, complete with pea clumps. I shocked and shocked and shocked and filtered filtered filtered and kept cleaning the filter daily, and when I could shock no more, I used a bottle of this Kem-Tek 60% and kept cleaning the filter daily. It took about a week and half to go from, seriously, split pea soup to clear and swimmable, and about two weeks to become sparkling clean.This algaecide is not magic. It takes work to clear up a lot of algae, but this product will definitely do its part.

### ⭐⭐⭐⭐⭐ Works like it should
*by W***L on April 11, 2025*

Very good algecide, keeps water clear and free of any algae. I use 4oz every 2 weeks and no issues all year long. Used for 7 years now. Highly recommended product.

### ⭐⭐⭐⭐ Good enough
*by S***A on October 5, 2013*

Did it work? YesI went on vacation and when I came home the pool was green. I ordered 2 bottles of this because it was a reasonable price and the reviews said it worked. I used an entire bottle and waited overnight. The pool was still green but not at bright. I added sink and sweep waited another day and and it was still green but settled on the bottom. After vacuuming it looked better but was not clean. I vacuumed every day for a 3-4 days and then it was sparkling again.I have been using the second bottle for a few weeks as a preventative measure and I am no longer having problems with algae growth. It would be nice if it worked faster but overall if you are not in a hurry to have your pool clean or just need something to prevent algae, this works well.
