    • 🌞 A Summer Pool Essential — Keeps the Water Crystal Clear!
Style: Algaecide Size: 0.25 Gallon
As an avid swimmer, BBQ lover, and backyard enthusiast, this In The Swim Super Algaecide is an absolute must-have for the summer months! My pool gets a ton of use between family swim days and weekend cookouts, and this product keeps it sparkling clean and algae-free all season long. It’s super easy to use — just pour it in and let it work its magic. There’s no harsh smell, no foaming, and no weird residue on the surface. I noticed a huge difference within a couple of days, and my pool stayed clear even during the hottest, busiest weeks. The 7.1% chelated copper formula really does its job — no yellow or mustard algae in sight. I love that it works equally well for above-ground and inground pools, and it doesn’t irritate skin or eyes. The stability and performance are top-notch, and for the price, it’s an incredible value — you get professional-level results without the professional price tag. Bottom line: If you love spending time outdoors and want a clean, inviting pool all summer long, this is a need, not a want. Great value for the money, durable results, and reliable protection — I’ll be keeping a bottle of this on hand every year! ... show more

    • Algae Began Dying Off Almost Immediately So It Could Be Filtered Out
Style: Algaecide Size: 0.25 Gallon
I'm a relatively new pool owner since I moved into my new house. When I ran out of the chemicals that were left behind by the previous owner, I picked this one up to help get rid of the algae that built up in the spring (we didn't open our pool until late because we had a vacation planned in June). To say our pool was green would be an understatement. When this algae cleaner arrived I followed the instructions on the bottle (I love that it has ounce markings on the side so it is easy to use the right amount based on pool size). The next morning, my pool was noticeably less green. I use those 'pool socks' on my filter, so I could also see TONS of algae getting filtered out, which means the algae was dying off and getting filtered out. Anyway, long story short, this product works as advertised and was priced right (which is why I bought it). It worked faster than I expected. It did take a few days for my water to become completely clear, but that was because the filter needed time to pull out all the dead algae. I'll also note that based on how much I used this treatment, I think this bottle will last me at least 2-3 summers. ... show more
