PoolRx+ Mineral Algaecide Unit, up to 6-Month Algae Control, for 2.5K-5K gallons, Red & White, New Formula with Silver.

Muy buen producto, mi alberca duró más de 6 meses muy limpia! Lo hemos vuelto a pedir!

Highly recommend! Helped our pool so much! My husband has struggled the last few years to keep our above ground pool looking blue and this was the fix! Our pool has never looked better! Buy it! It’s worth it!!!

I placed this unit in my pool pump’s leaf strainer. After approximately 24 to 48 hours, all the algae was dead without the need for shock or any other treatment. However, after shocking it, the blooms ceased to reappear, and I haven’t had to shock it in the past two weeks. It's so easy to use just toss it in and let it do its thing no hassles. It's saving me so much frustration and fits perfectly for my pool size 5k gallons

Been using for a month now. My first time. Water is clear. Seems to be effective.

I would work for this company. Last year, we thought we lost our pool looking online. Everyone recommended this product. Within minutes, you could see it working I couldn’t believe my eyes. I will use this product over and over and saved my pool for the rest of the summer. We look forward to using this product every year. It’s amazing. I can’t say enough great things about it. The water balance the value for your money.
