Title: I got the blues
Review: This product is made by a company which also makes a similar cartridge in bleach. There is no comparison between their performance. They are designed to keep your toilet bowl clean by dispensing a measured amount of cleaner with each flush. The bleach cartridge keeps the bowl clean for weeks, the blue one keeps the water blue, and that's about it. A third product is made for septic tanks.
