Review: Works with Fluidmaster Flush & Sparkle. - Works with Fluidmaster Flush & Sparkle. If you're tired of spending so much money on refills for your fluidmaster toilet cleaning system then use these tablets instead of replacing the entire cartridge. The bottom cap pops off and 4 of these tablets fit perfectly inside. It does have a chlorine odor but it's not too strong and to be honest, that's the only way of knowing it's working without taking off the tank lid. I haven't used this long enough to see how long it lasts but it's certainly way cheaper than new cartridges. You may have to replace the cartrige o-ring or at least lube it so that it last longer.

### ⭐⭐⭐⭐⭐ Can use these for Fluidmaster Flush n' Sparkle toilet bowl cleaner
*by R***N on April 8, 2025*

Fluidmaster Flush n' Sparkle is a great product for keeping your toilet bowl sanitized -- it releases chlorine into the water with each flush, but without chlorinating the water in the tank which can cause degradation of seals and other parts. Unfortunately, Fluidmaster charges a hefty price for every single refill (needed about every 6 weeks in my experience). Instead, you can refill the Fluidmaster cylinder with 3 of these tablets at a fraction of their cost. You just have to pry the bottom cap off of the cylinder, which is admittedly difficult but worth the effort. I use a screwdriver tip to pry and push the cap off. I removed the foam rubber spacer that's in the Fluidmaster cylinder (not sure what its purpose is), and the cleaning system works just great.
