PoolRx+ Mineral Algaecide Unit

Can't say enough about this product and how it has eliminated my algae problem. It's nice to brush my pool walls without seeing green debris coming off the side walls. I could never keep up with the brushing. I could see the results in a few days in my skimmers and on the Polaris pool sweep bag - No more green tinge. Luckily, my pool is dark blue, so any possibility of staining my plaster will not be an issue. I have a large pool, so I got the item with the booster. Both were easy to apply; I just placed them in my skimmer as directed. Received in nice, sturdy packaging.
