poolrxpool unit 7.5k-20k gallons

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.

I’ve been using Pool RX in my saltwater pool for a month, and the results have been fantastic! This little blue mineral pod has made a noticeable difference in water clarity and algae control. My pool stays cleaner longer, and I’ve been able to reduce chlorine usage without sacrificing water quality.Installation was super easy—just drop it in the pool pump basket, and it does its job. I’ve had no issues with scaling and cloudy water since using it. Highly recommend **Pool RX** to any saltwater pool owner looking for a simple, effective way to maintain crystal-clear water with less hassle!5/5 stars – A game-changer for pool maintenance!

We have been very frustrated with black algie growth as well as mustard algie so hard to get rid of. I decided to try this. I put in the skimmer basket and hoped for the best. After 4 days of running the filter with this cartridge in the skimmer what a difference. My pool is super clear and I can see the stains slowly disappearing . I am grateful for this product. We live in florida so with temps and humidity its extremely difficult to sometimes get this pool right. So far so good. The water is so clear too. Thank you for this miracle worker.

Mine didn't seem to work as fast as advertised, but this product WORKS! My pool looked worse than shreks swamp, black mold etc which i have been struggling to get rid of. Directions were simple enough, made sure my numbers were where they needed to be. I have a cartridge filter so I followed the instructions for my setup. And within a week my pool was saved!Hardest part was probably being diligent in cleaning my filters every other day. But as long as you do that, product worked like a charm and I'm definitely buying more for future seasons!

Every season I buy this for our pool. We have an above ground 20k gallon pool and this cuts down on algae 100% i only ever have to keep chlorine in the pool and clarifier sometimes. I will still do algaecide every now and then just to assist but that’s it. It’s worth the money!

My pool was cloudy for well over a week. Nothing was getting it clear and I was on top of everything. I set this up in the skimmer basket and within 2 days it was 90% more clear! BUT it appears that this little guy is too large for my skimmer because it doesn't seem to suck debris as well with this inside the basket (our pool has a very small 6" basket). So overall this seems to have worked very well but ultimately i have to figure out a different way to do it because is wasn't cleaning out the debris. For $50, I would still recommend this.

I don’t have high expectations for pool algaecide products. Before ordering this I used an entire gallon of a product made by that big bleach company that also makes pool products, and that didn’t work. So, I bit the bullet and paid for this pricier option. Well after two days my mustard algae was dead. I brushed and vacuumed the pool, then changed the filters and the algae has not come back. I would buy this product again. If you are on the fence, just get it. It works.

I will reorder, but I'm going to try the version that treats 2-5k gallons to see if this corrects the film it leaves on water surface.PROS:• I haven't had an ounce of algae all year. Crystal clear water.• It lasted longer than 6 months.• Cuts down on amount of chlorine needed each week, having to purchase and add additional chemicals weekly, and overall maintenance time.CONS:• In undisturbed water, a film develops on top of water. Film on apparent for first 3 months. This can be skimmed off with net with small mesh.• Blue film also collects in paper filter, but can be sprayed out with a hose.• If pH & Chlorine get out of balance, it left brown stains on my pool liner. Once pool is balanced, they disappear. For stubborn stains, place a chlorine tablet on stain for a minute or two, stain disappears.
