## Customer Reviews

### ⭐⭐⭐⭐⭐ Offline chlorine feeder
*by C***Y on June 1, 2025*

Great product 👌 strongly recommend

### ⭐⭐⭐⭐⭐ got chlorine up ,nothing in pool floating around
*by V***T on July 15, 2025*

finally got my chlorine lever up and correct after 2 days ,easy install

### ⭐⭐⭐⭐⭐ Install is even easier than the videos make it look
*by W***L on July 19, 2024*

My old in-line chlorinator cracked, and the tech opening my pool charged me a small amount to take it out and put a straight pipe in. Recommended I get an off line chlorinator as they work well and are easily replaced if you have an issue. Initially got a quote from a pool service vendor, but was pretty high ($450). Most of the install videos look pretty straightforward, so I figured I'd buy this one and DIY. Was even easier than the videos made it look. Recommendation, start with the flow setting about the mid point and adjust. I started with higher flow, and ran through 9 or 10 discs in a few days. Mid point made the pucks last longer (about a week), and the pool looks great.
