I bought this in Dec 2016 and am now replacing the anode. My pool has never looked better!!

This works like a charm but you'll need to purchase the floating case and coil that holds the copper anode. So simply to use and does exactly what it says it'll do.

Have a 74,000 gallon pool & 3 of them solved my problem, just love that I am not using the vast amount of chlorine I was & the clarity of the water is perfect.

We have been using this product for 3 years in our inground pool and it works unbelievably well! We no longer use chlorine with the exception of occasional shock.

While this product does work, the copper it adds to the water will give a green tint to those with light blonde hair... Source: the unhappy wife with newly green hair.

After 3 months of use in hot and humid Florida my pool is pristine. I hated my pool before this product. I can see why I have never seen this in pool stores it would decrease their business. Wish I had come across this years ago.

Works fabulous

Second summer with this bad boy. Our pool is looking beautiful. Chlorine is nearly impossible to come across now Adays. These work, that's it

These are amazing

This item is Not As Advertised. It's a copper bar that the AD says to float in the pool; and the AD shows a "housing unit" that holds the bar. The bar is quite heavy and is NOT going to float by itself. I received the bar in a plain brown cardboard holder, NO instructions and No indication of the floating housing is following. I do not see how this is supposed to work; I want my money back.
