Review: Best algae treatment ever
Review: I’ve been using the PoolRX+ in our 15,000-gallon pool for the past few months, and it has truly been a transformative experience. For years, we struggled with relentless algae problems every summer, which made maintaining our pool a frustrating and labor-intensive task. Thankfully, the PoolRX+ has completely changed that. Installation was a breeze. I started by cleaning the pool filters thoroughly, which is crucial for optimal performance. Once the filters were clean, I simply installed the PoolRX+ unit into our pool filter system. It was as straightforward as promised—no extra tools or complicated procedures required. The results have been nothing short of amazing. Since adding the PoolRX+, our pool has stayed consistently clear, and algae has become a thing of the past. It’s remarkable how much easier pool maintenance has become. What used to be a major chore has turned into a quick and effortless task. We’ve also noticed a significant reduction in the amount of chemicals we need to use. The PoolRX+ effectively reduces the need for heavy chemical treatments, which not only saves us money but also creates a safer environment for our family. With the PoolRX+, our pool water remains clean and balanced with far fewer chemicals, which is a huge plus. The unit has proven to be durable and reliable, lasting between 5 to 6 months before needing replacement. This longevity ensures that we get through the entire summer season without any interruptions or additional purchases. One thing to note is that the PoolRX+ raises the copper levels in the water. While this is a natural outcome and not a major concern, it’s worth being aware of. The benefits far outweigh this minor issue, as the copper helps in maintaining algae-free water. In summary, the PoolRX+ has been an absolute game-changer for us. It has drastically improved our pool maintenance routine and allowed us to enjoy a clean, algae-free pool with minimal effort. I highly recommend the PoolRX+ to anyone dealing with algae issues or looking to simplify their pool care. It’s a fantastic investment that delivers impressive results!

## Questions & Answers

**Q: Has anyone else had a problem after using this product with it turning your blonde hair green.**
A: According to the Pool RX website, if hair turns green it’s because the chlorine is too high and reacting with the minerals in pool RX.  Recommend chlorine level while using pool RX is 1 to 1.5 ppm.  Not the normal 2 to 3 ppm recommendation for a residential pool.  Hope that helps

**Q: Does it work for black algae**
A: I use no algaecide now and my water is crystal clear. A properly maintained pool will not be susceptible to algae blooms. I use only chlorine, acid, base, and stabilizer. If you live in an area with high phosphates, you may wish to add some Phosfree+ to eliminate excess amounts as they are food for algae. Go to troublefreepool's website (100% free and an awesome community) to learn about your water chemistry and the proper methods/tools to test it. They also have chemical calculators and forums for resolving issues (e.g. algae blooms, cloudy water, etc). Good luck

**Q: This stained my inground pool with dark gray stains. UGLY!  Are they "metal" stains?  What would be the best STAIN REMOVER to buy to remove them?**
A: For this staining you need to have a professional to analyze your pool water. I did not have stains as a result of Pool RX. But my water is clear and no algae  so far.

**Q: I purchased in March, worked great when weather was not hot, now it’s not helping at all. Pool is green and it’s cloudy too. How long should it last?**
A: If your pool had a lot to clean up I think it doesn’t last as long. Also did you clean your filter when you put in the pool RX? My first one didn’t last as long so I got the poll RX plus. It’s been doing a great job. Also the pool gallons or size effects the longevity.

### ⭐⭐⭐⭐⭐ Review
*by H***Y on 3 April 2025*

I've been using this PoolRx device for almost a year and a half. It is ABSOLUTELY BRILLIANT!! Prior to this, I was using a floating Solar Shock unit which I purchased online from Costco. The Solar Shock worked well, but required weekly copper rod cleaning that was a PITA!!! It was messy, requiring you to scrape the copper rod with a wire brush, and soak the screen filter housing in CLR to keep it from getting completely calcified from hard water. During a calcium build-up cleaning by a professional company, I inquired about their weekly pool service (just to see what it would cost). When i got the quote from them, I noticed that they required that you have a PoolRx unit in order for them to honor the price they quoted. I had never heard of it, so I did a quick search and found that it's basically a MUCH BETTER version of the Solar Shock unit. You stick this item inside the pump basket. When your pool pump runs for normal cleaning, the chemicals inside this device disperse into your pool (it's invisible...no noticeable chemical smells or color). As these chemicals pass back through the pump basket, they interact with the copper rod located on the inside of the device and it actively keeps algae from growing in your pool. You still need to maintain some chlorine in your pool, but it has literally cut my chlorine usage IN HALF during the summer months in AZ. I went from 4+ chlorine tabs per week (in the 110+ degree summer months) down to 2. In the winter months, I use about 1 chlorine tablet every 2 weeks. I also have a unique "water wall" that acts like a high-end spa where water flows down the wall and creates a unique ambiance. The top of this water wall has a trough that stores a lot of water and during the summer months, that water can get NASTY in a hurry. I run the pump for this twice a day during the summer months to cycle the water, but with this PoolRx unit, a couple chlorine tabs and weekly shock treatments (necessary for my setup) my pool is crystal clear with absolutely no algae build-up (even when the water temps reach the 90s). Several summers back, even with the Solar Shock unit, I could not get the algae under control and eventually had to drain the pool, get it acid washed and start over. Take it from someone who has to maintain a pool in AZ, this thing WORKS! You need to add the refill chemicals every 4 to 6 months to keep everything working and you need to replace the whole PoolRx unit every year because the copper rod dissolves over time. For peace of mind knowing I won't have algae, the cost savings of 1/2 the chlorine usage, and it doesn't require maintenance...this thing is absolutely getting 5 stars from me. Hope this review helps.
