Each unit lasts up to 6 months, reducing chemical use by enhancing chlorine efficiency. Easy to use by placing in the pump or skimmer basket, PoolRx simplifies pool maintenance and is ideal for both residential and saltwater pools. ## Description The 4pack of PoolRx Blue Units is just that. 4 individual units, each PoolRx Blue Unit supports 7, 500 - 20, 000 gallon pools. PoolRx is an easy to use algaecide that reduces chemical demand, improves water quality, lasts for up to 6 months, and really works! PoolRx contains a proprietary blend of minerals that continuously and effectively eliminates algae. Simply pick the correct sized PoolRx unit based on total gallons, clean your filter first, then, drop the PoolRx unit into the pump basket or skimmer. The specially treated alloy cylinder is packed with the PoolRx mineral formulation. These minerals immediately dissolve out of the cylinder and form a stable residual throughout the pool water for up to 6 months. The minerals eliminate the algae while freeing up low levels of chlorine to be more active and productive in the water. During the pools filtration process the minerals are rejuvenated every time they return and pass through the cylinder. PoolRx works synergistically with a constant low level of chlorine. Residential (0. 5-1. 0ppm); Commercial (1. 0-5. 5ppm) If needed, a PoolRx Booster The (part# 102001) can be added for longer seasons, larger pools or tough condition. The PoolRx unit is effective in rejuvenating minerals for up to 1 year in the water, so start with a new PoolRx unit at the beginning of each season for best results. PoolRx has been simplifying pool and spa care since 1994 and can support any size body of water. PoolRx is also ideal for Salt Pools. ## Features - Simply place in pump basket or skimmer basket - Eliminates all types of Algae - Reduces Chemicals - Effective for up to 6 months - Simplifies Pool and Spa Care ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00K65T1CW | | Best Sellers Rank | #3,644 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #12 in Swimming Pool Algaecides | | Brand Name | poolrx | | Customer Reviews | 4.5 4.5 out of 5 stars (9,964) | | Included Components | PoolRx 4pack of Blue Units, each supports 7,500-20,000 gallons, and directions for use | | Item Form | Tablet | | Item Type Name | Swimming Pool Algaecide | | Item Weight | 13.1 ounces | | Manufacturer | PoolRx | | Manufacturer Part Number | 101003 | | Model Number | 101003 | | Number of Items | 4 | | Number of Packs | 4 | | Package Size Name | 4 Pack | | Product Benefits | Controls Algae | | UPC | 705532371023 700553010036 | | Unit Count | 4 Count | ## Product Details - **Brand:** poolrx - **Item Form:** Tablet - **Item Weight:** 13.1 ounces - **Product Benefits:** Controls Algae - **UPC:** 705532371023 700553010036 ## Images ![PoolRx 101003 4-Pack Blue Units Swimming Pool Algaecide, 4 Pack - Image 1](https://m.media-amazon.com/images/I/61PQLL+9hYL.jpg) ![PoolRx 101003 4-Pack Blue Units Swimming Pool Algaecide, 4 Pack - Image 2](https://m.media-amazon.com/images/I/41BTVeGnC5L.jpg) ![PoolRx 101003 4-Pack Blue Units Swimming Pool Algaecide, 4 Pack - Image 3](https://m.media-amazon.com/images/I/41tlp7SeawL.jpg) ![PoolRx 101003 4-Pack Blue Units Swimming Pool Algaecide, 4 Pack - Image 4](https://m.media-amazon.com/images/I/51lJW-rReGL.jpg) ![PoolRx 101003 4-Pack Blue Units Swimming Pool Algaecide, 4 Pack - Image 5](https://m.media-amazon.com/images/I/41IuUr05qRL.jpg) ## Available Options This product comes in different **Pattern, Size** options. ## Frequently Bought Together - Pool RX 101003 Swimming Pool Algaecide, 4 Pack, Blue - PoolRX+ Pool Unit 20k-30k gallons (4-Pack) - PoolRx Booster Minerals for Pool, 7500 to 20000 gallons,4 Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/61103687-poolrx-101003-4-pack-blue-units-swimming-pool-algaecide-4](https://www.desertcart.com.br/products/61103687-poolrx-101003-4-pack-blue-units-swimming-pool-algaecide-4) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-09-30*
