poolrxPool Unit #101066 6 Month Algaecide Treats 20k-30k gallons, Black

Every spring, I make it a point to purchase this product as part of my routine to prepare for the warmer months ahead. It effectively combats algae growth while ensuring that the chemical balance of my pool water remains optimal. I’ve found that it not only keeps the water clear and sparkling but also maintains a safe swimming environment for my family and friends. Although it may be on the pricier side, I truly believe the benefits it provides are well worth the investment, resulting in a refreshing and enjoyable swimming experience all season long.

I love this product. It eliminates algae. I highly recommend this. It says they last 6 months but I have had one last that long. I went through 2 of them last summer. Which is still way cheaper that all the shock and other chemicals I was using every week and still fight an algae problem. The first one lasted about 2 months. The second one last through the winter.When I opened the pool this year I still had a fairly new one that I used at the end if the summer. I saved it and used it to open my pool this year. My pool was so green that you could not see the bottom. I opened the pool but didn’t have time to shock it or do anything. I stuck the pool RX on the skimmer to see if it would help at all. 1 week later my pool was clear with zero shock used. That blew my mind. I thought it was just a preventative but it killed all the algae and cleared the pool up.My water started getting green again a month later so I shocked it and bought this Pool RX to start the new pool season.I still use a chlorine tab floater but I don’t shock the pool but maybe once a month now. I only do that because people say I should. But my water is crystal clear. Just try it. I think you will be impressed. But you will likely need two of the to complete the pool season. But it is worth it because the maintenance is down to basically just vacuuming once a week.

Works great!! Highly effective at minimizing algae growth while significantly reducing chemical usage.

To be honest, I was putting off purchasing this, I thought it was a gimmick but I figured I’d have nothing to lose being I was unable to get my pool water as clear as it should be. What an amazing product, after about two days my water is crystal clear. I still have some mustard algae laying on the bottom seams of the pool but I’ll just put my filter on waste and vacuum it out, it doesn’t seem to kill the mustard algae all that well but no complaints here. I will be purchasing this product every season.

The Pool RX-Black works well... It is expensive ($90/unit-good for a 25-30K gallon pool) and in the CA summer heat may not last the full advertized 6 mos effective life. It also requires that you keep your pool chemistry balanced (free Chlorine levels, pH, Alkalinity, Ca Hardness). I have tried a number of other liquid algicides with mostly marginal to poor results - they are all expensive, especially if you have to keep adding more because they aren't doing an effective job and you have to do extensive cleaning to keep the algae off the bottom and sides of the pool. The Pool RX unit just sits in the skimmer or pre-filter basket and controls both black and yellow algae (good pool chemistry is important). If I got the full 6 mos of effective control with one unit, I would have given Pool RX 5 stars.

This is hands down on of the best things you can buy to keep your pool clean and clear. I love this hidden gem. If you want a lot less work and a lot less chemicals in your pool then buy these...

This is a great product! I stopped buying chemicals every week since I started using PoolRX. No more algae in my pool.

This is a game changer!!! I’m not one to write a review but this is well worth it!! Our pool is crystal clear
