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.

PoolRx Pool Unit #101001 6 Month Algaecide Treats 7.5k - 20k gallons
The blue Pool Rx pool unit is an EPA Registered, NSF/ANSI 50 Certified, swimming pool algaecide supporting 7.5k-20K gallons of water.
The Pool Rx pool unit contains a proprietary blend of minerals that continuously and effectively eliminate algae. The specially treated alloy cylinder is packed with Pool Rx granular formulation. These minerals immediately dissolve out of the cylinder and form a stable residual throughout the pool water. The minerals eliminate the algae while freeing up low levels of chlorine to be more active and productive in the water. During the pool's filtration process the minerals are rejuvenated every time they return and pass through the cylinder.
The granular minerals are lost from algae kill, backwashing, splash out and filter cleaning. The harder the minerals work and the tougher the conditions, the shorter their lifespan. PoolRx works synergistically with a constant low level of chlorine. Residential (0.5 - 1.0 ppm) Commercial (1.0 - 5.0 ppm).
Replace the Pool Rx pool unit at the beginning of each season for best results. Pool Rx is ideal for use with Chlorine, Salt, UV or Ozone systems. Supporting any size body of water, Pool Rx+ is perfect for both Residential and Commercial pools.

Miracle gadget
This product is amazing. I put it into my pool pumb and it started to work right away. After two to three hours I could tell the difference already. After a day or two the pool water was crystal clear. I had never been able to get this done with just shock, chlorine and PH. I put this gadget now in my skimmer and prefer to leave it there to allow the pool pump to be free and clear. It works there just as fine. I put it in Monday and today is Sunday. A whole week and so far had not added any additional chemicals. My pool is a 12.000 Gallon pool, but this works great in bigger pools as well up to 20K Gallon. if you have a bigger pool just place two in the basket. Great product and worth the money and more. I highly recommend Pool RX 101001. Lets see how long it lasts...I am hopeful.
