So, I've had a chance to use this product for a while and write a proper review. I have an inground vinyl lined pool of about 25,000 gallons. For 32 years I have had issues dealing with algae. I was tired of spending a $100 on a gallon of algaecide at Leslie's that was barely effective and would still get some algae. I saw Pool Rix and decided to give it a try. The description states that it will last up to 6 months. Our summers are brutal with a lot of days over 100 degrees and decided if this controlled algae for at least three months I would be very pleased. Yesterday was the three month period and I have not seen a speck of algae since I started using Pool Rx. That has never happened in 32 years. I am very pleased how this has worked in my pool. As an added benefit I am using far less chlorine in the pool. With dichlor costing $300 for 50 lbs, this product is paying for itself. I even bought the booster but haven't had to use it yet. I would highly recommend this for anyone's pool.

We purchased one of these in March when we bought a house with a pool for the first time. Our pool remained crystal clear and clean all summer. We have now reached the end of August, 5 months, and started noticing some algae and cloudiness, even though we shocked and maintained the chlorine. I realized the PoolRX was likely at the end of its life, so we ordered another one and installed as soon as it arrived. The pool cleared up overnight, the algae brushed off the walls and the pool looks crystal clear again! Excellent product! Highly recommend. For reference we have a 30K gallon pool and live in North Texas.

This product works really well! Since adding it to my pool, I haven’t had any issues with algae at all. It’s easy to use, lasts for months, and keeps the water clear without constant maintenance. Definitely worth it for reliable algae prevention and peace of mind.

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.

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.

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.

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.
