poolrxspa Unit 400-1,000 gallons

These are a must have for pools....if you know you know

Item arrived on time and in condition described. The pool guy thinks this is an excellent product.

Ive had my pool for years and the list thing kept it clear the entire summer. I will absolutely use this every year. I couldn’t believe how clear my water stayed.

Works as promised. Places in pool and next day clear water. Stayed clear for the promised time. Would purchase again.

My water-fall pond (without fish or plants) is 450 gallons.The instructions state to place the metal diffuser in a high-flow area like a skimmer or pump basket. Since I have no skimmer, I placed it at the bottom of my pump vault where water is sucked in for distribution.After a day the water seemed slightly cloudy so I checked on the device. I reached down into the cloudy vault, felt around and found the object, lifting it to the surface. In the process, a lot of concentrated blue water dumped out. The object apparently wasn't receiving enough water flow to distribute the metals.I moved the diffuser (which, by website, rejuvenates the electrical charge on the metals when the ions pass through the caged unit) to a visible area where I could see current.The device appears to be working well over the 2 weeks it's been in use. I have lightly, green-tinged foam (edges) that collects at the end of the last stream bed, where the water drops down to a rock-covered underground reservoir. No visible algae growth is apparent anywhere. However, I had a yellow-mustard algae outbreak last year and despite repeated treatments, is still present in the typical sand/dirt appearance. This algae hasn't "grown out" into a vegetative state but I had hoped that the algicide would have killed and eliminated the sandy-appearing algae spores. I'm speculating that this algicide is mostly a preventative agent (against mass reproduction that leads to vegetative growth).Note- value and longevity rating is based on company spec. It may provide a one-time, "drop into the water" convenience but most water features require some form of attendance weekly (or bi-weekly) so an algicide that is applied at the same time and works just as efficiently would prove to be a better value for the money.The website has a FAQ section but some of the answers are incomplete sentences, as if the answer exceeded the available space and therefore wasn't displayed. The website also lacked a more complete description of how the product works. That may not be a huge deal for most people UNLESS they are planning to put any form of life into their water feature. Since most companies selling a product are only interested in telling you what THEY want you to know, to buy the product, the information is biased to one side-the seller. I suggest every consumer do their due diligence in researching the company, product and mechanism to get a more complete picture before buying.

I guess this is some kind of upgraded version but it’s not good. Floats in the pool vs being placed inside the filter basket or inside the filter cartridge. That kind worked fantastically last summer and I had no issues. It was a life saver. This floating version doesn’t work AT ALL. There is literally algae growing ON the product. And I have non stop algae growing at my water line all the way around the pool. I have a small pool that is only 880 gallons and I clean my filter daily and replace every 2 weeks unless it’s needed sooner. I’m already on my 4th filter and I bought this a month ago. I have added the recommended amount of chlorine that the manufacturer says is needed which is a small amount and I skim and scrub my pool every single day and it still is just a constant battle. I wish I could just buy the same unit as last year but it isn’t available any more I guess. How disgusting because the little filter cartridge sized one was such a miracle and now we can’t even use our pool because it’s so gross every day. I am returning today for a refund.

Living in Florida tends to give us tons of pollen all year round. I fought for 6 months to get the pool clear and used hundreds of dollars in chemicals. We added this to the filter of our above ground pool. Within a day we noticed a difference. By the end of the week, the pool was about 75% better than it had been all year. By the end of the month it looked like a showroom pool! Wish I knew about this earlier! Would have saved hundreds of dollars!

Too small for the price
