## Description

PoolRx Pool Unit #101001 6 Month Algaecide Blue Treats 7.5k-20k gallons, Single

Review: It works super fast too! - UPDATE AFTER JUST OVER A MONTH: This is worth every single penny spent! Two days after I put this in my pool was completely algea free and has remained so. We have had very high temps and humidity (in the 100's) for the last month and my water has been clearer than when I filled it up when it was brand new. I did notice my pump was acting wonky after 5 days so I had to backwash which I was afraid would mess up the progress but it was fine (you're not supposed to backwash for 2 weeks after dropping it in). I did move it to the pump basket after that and no more issues. I have backwashed once since then. I put in one arm and hammer tablet and one chlorine tablet (clorox Xtra blue) once a week and my levels are always perfect. I haven't shocked my pool at all since adding this ball, the amount of money I'm saving on chemicals has made this ball very cost effective! I did notice this morning my pool isn't as clear as it has been and it's time for me to change out the ball. Probably didn't last as long because I backwashed after the first 5 days but I'm not complaining. I'll switch it out and enjoy another 5 weeks or so of a virtually maintenance free pool. Do not hesitate to order this! I didn't take a before picture but I swear this thing is a miracle worker! We put up a 17'x48" summerwaves pool last year and everything was great for 3 weeks. Then the yellow algea appeared. I triple shocked, vacuumed, brushed, over and over and over for weeks but the algea would never fully go away. The water would just be cloudy all the time. I kept my water balanced and just couldn't get it clear no matter what I tried. I finally drained it halfway and refilled, that helped for the last few months of summer but still, it never got really clear again. So this year I emptied the pool, gave it a good scrub and then started over. I had done my research and figured I knew what I did wrong. Things were great this season, opening the pool in May and for two months my water was perfect. Then we had the typical extreme heat and high humidity come in for a week, bam, yellow algea. I was frustrated. I gave it a good scrub and vacuum, and a quadruple shock. Two days later and zero difference. I saw this little thing, even though pricey, based on reviews I had to try it. It came in yesterday and I brushed the walls and floor, backwashed my sand filter and dropped this suckered in the bottom of the skimmer (I have a skimmer/pump that came with the pool and is not turned on, it's connected to the sand filter so putting it in the bottom of the skimmer is the same as putting it in the pump basket for reference). That was at 5pm yesterday. My pool had tons of yellow algea everywhere and the vacuum would only stir it up so I was hoping for a miracle. At 9am this morning I came outside and the pool is almost completely free of the yellow algea! I have a few small spots by the steps that I will see if the vaccum can get and if not I'll just brush it into the water to let the pump filter it out. This is so worth the money! I don't know how high my chlorine is because we have a tropical storm today and I really can't get out to mess with the pool but as of now, if it's too high and won't budge I am perfectly fine with draining some of the water to get rid of that, at least I know for sure algea won't be my problem in the future! If anything changes I will definitely update this review.
Review: Great little helper for keeping the pool crystal clear! - I’ve been using the blue PoolRx unit for one season now, and it’s honestly become one of my favorite pool maintenance tools. I just drop it in the pump basket at the beginning of the season and let it do its thing — it helps keep algae away and really seems to take the pressure off my chlorine. My pool is around 8k gallons, and this unit is rated perfectly for that size. Once it’s in, the water stays noticeably clearer with fewer chemical adjustments. I’ve also been able to keep my chlorine levels on the lower end (which is great for the wallet and our skin). I love that it lasts a solid 6 months — though if you’ve got a lot of splash-out or backwashing, it might wear out sooner. Super easy to use, no measuring or mixing, just drop it in. I make sure to replace it every season like they recommend, and so far, no algae issues at all. Highly recommend for anyone who wants to simplify pool care.

## Questions & Answers

**Q: How long after I drop the pool rx in the skimmer basket should I take it out?  Or do you leave it in permanently?**
A: The PoolRx unit has a effective life of 12 months in the water. After the first 4-6 months you will need to add 1 PoolRx booster (#102001) per 20k gallons for the product to continue to work for the remaining life span of the unit.

So NO absolutely do not remove the unit from the skimmer. It needs to remain in the pool for the minerals to continue to work.

**Q: can you use in lieu of filter cartridge? Pressure issues with cartridge hoping to use this instead.**
A: No you cannot, this product is not a replacement for filter medium you still need a cartridge in your filter. Is the pressure issue you are referring to related to install of PoolRx or is it a ongoing issue? If it is related to install of PoolRx remember you always need to clean or backwash your filter prior to install of PoolRx unit or Booster and keep the pump running for at least 6-8 hours upon install. In some instances you may still experience a rise in pressure for several hours after install while the PoolRx minerals dissolve into solutiom. Once the minerals have dissolved your pressure will return to normal level.

**Q: The tds (total dissolved solids) level is too high & i was told to drain the pool. does poolrx still works at high tds without draining?**
A: If your TDS level is 4,000 ppm or more you will need drain your pool and re-fill to lower your TDS level. This will allow PoolRx to work properly.

**Q: Have a pool 25'x 50' about 45,000 gallon how many PoolRx blue do I need ?**
A: I would say 2-3 as mine is 15000 gallons and needed 1.

### ⭐⭐⭐⭐⭐ Absolutely AWESOME!!
*by D***E on August 16, 2023*

This has been the BEST pool season ever!!! I can’t believe how much money in chemicals I saved using the Pool RX!!!! I waited to write a review as I was very skeptical if this was going to really work. I’ve had it in my pool for 3 months and can’t believe how AWESOME the Pool RX works!! I live in Michigan, get lots of rain and fight with algae every year. After reading the reviews, doing research I bit the bullet hoping to save money on algicide and chemicals. The instructions said do not backwash the filter for 2 weeks after the product dissolved. I have to say, there is no way I have ever gone 2 weeks without backwashing but I’ll be darned, I didn’t have to and the algae was gone and my water has never been so crystal clear!!! I have 18,000 gallons in my pool and the research says you don’t have to shock your water weekly. Again, I thought that was impossible! I did shocked my pool 14 days after added Pool RX - only because I was scared my water would turn cloudy or green even though it was crystal clear. I had to close my floating chlorine thingy because the chlorine levels were so high - which again surprised me because they say you’ll use less chlorine and that was so true!! As the end of the season is approaching, I’ve only shocked my pool 3 times this season, used a fraction of the chlorine tabs I always used and can’t believe my water is crystal clear! I’ve always had to add phosphate remover every year and the instructions stated you won’t have to add any and again, I didn’t!! I can’t believe I’ve only had to spend $75.00 for the Pool RX, have used 6 gallons of liquid chlorine (which I got an awesome sale price of $3.00 a gallon) and approximately 16 of the 3” chlorine tablets so far this season!!! I absolutely LOVE this product, have recommended to everyone of my pool friends and will definitely use this every year here out!!! Thank you Piol RX!!!
