    • Easiest pool season yet with PoolRX
Style: Single Unit
We've had pools for 5 years and this year has been the easiest for chemicals and cleaning with PoolRx. I was hopeful it would help as we have struggled with algae in the Texas heat. This has surpassed my expectation. The water is clear and clean for the past month with minimal chlorine - 1 regular chlorine tab a week for our 6,000 gallons. The Orange/white plastic ball sits in the skimmer, so easy to use. I did follow the directions and ran the sand filter on recirculate for awhile first, and then have been filtering/backwashing/rinsing as normal. Time will tell how long it lasts but based on others reviews it should last the season. I think it is worth what I paid for it, around $50. I would have already bought that much chlorine for shock based on last year. I will try to update at the end of the season with thoughts. ... show more

    • Magic!!

I don’t understand how this works but it is literally magic! We have a smaller 12ft above ground pool that constantly has algae growth on the sides and in the tubing. We are in FL so the constant rain and heat evaporating the chlorine don’t help. I plopped this thing in my strainer basket, and within a few days the algae that had accumulated in the tubing was GONE…I was shocked and within a week all the stubborn algae on the sides was dead and I was able to vacuum it up from the bottom. It’s been another week and my pool is CRYSTAL clear with minimal chlorine tablets. Absolutely amazing, I will buy this year after year!! ... show more

    • Pool Rx gained a new customer.
Style: Single Unit
I have an 18x48 Coleman above ground pool with an Intex salt and sand pump. Added five 40 lb bags of salt and the orange Pool Rx in the skimmer for the pump. Pool has been up for two weeks with rainstorms and showers almost daily. Pool water is still clear as the day I filled it. Routine maintenance to remove bugs and leaves as well as vacuuming with an Intex vacuum. During the past few years, our pool has turned cloudy and/or green within a few weeks of setting up the pool due to a magnolia tree nearby and rain showers or storms May through July. So far, Pool Rx has kept me from having to use any chemicals. ... show more

    • Works like it should
Style: Single Unit
It works as advertised. I expected there to be more of it, but it worked well for how much there was. My husband said it was okay, but he probably wouldn't buy it again as there are cheaper options.
