Fluidmaster 8102P8 Flush 'n Sparkle Automatic Toilet Bowl Cleaning System Refills, Blue 2-Pack, Upgraded Version

Great product

when I bought the system it came with a clear bleach cartridge. It worked so great that I bought one for my sister who's selling her condo. It worked so well, I bought replacement cartridges. The replacement was blue bleach. Terrible!!!! It swelled up and clogged the system after a couple of flushes. I eventually threw them away. I don't see replacement cartridges with clear bleach, only the blue. Bad business, unless the company starts coming out with the clear replacement cartridges ill be buying the tablets for the bowl.

Purchased this from Amazon US as they are not available in Australia even tho Fluidmaster toilet cistern spares are,I spoke with Fluidmaster here in Australia told him i had a Coroma float in my cistern and he told me how to make it work for the Fluidmaster device. It works as is described in the brochure/ add but the colour/cleaner cartridge seems to clog up and doesn't allow the product to dispense. Searching through my shed i found a Fluidmaster valve and float assembly purchased as a replacement along time back but never got around to using it, I will install this in my cistern although the operation appears to be the same hookup as the Coroma float, If it works I will modify this review to reflect same.

I have been using the Fluidmaster Flush 'n Sparkle Cleaning system for about four years to help control black mold and mildew that tends to grow under the rim and in the bowl. The chlorine bleach cartridges have definitely helped control the excessive mold and mildew buildup but I still needed to manually clean the bowl every week or two to keep the problem under control. I recently decided to try out the blue cartridges to see how well they worked and see if there was any difference. To my surprise it seems as though the blue detergent cartridges are doing a better job at controlling the mildew under the rim of my toilet than the white chlorine cartridges were. My water supply tends to be heavy in minerals (particularly calcium) and it is treated strongly with chlorine/chloramine. It seems both the white and blue cartridge work well but their effectiveness might depend on how chlorinated your water supply already is and what type of growth or deposits you are getting in your toilet bowl.Conclusion: I recommend that users of the Fluidmaster system test both types or try alternating both types of cleaning cartridges and see which works best for your particular situation. As a plus the blue detergent cartridges are less expensive but unfortunately they do need to be replaced more often than the bleach ones which for me last up to four months. I would also suggest installing a fill valve with a system to control the flow of wasted excess water from overfilling the bowl. I am using the HydroClean HC660 fill valve with a built in water bowl overflow control but Fluidmaster also sells a good system that can be added on to an existing fill valve and adapted with an adjustable pinch roller with pressure clamps that slide on tubing between the fill valve and the Flush and Sparkle system (or use the complete kit, Fluidmaster 400ARHR High Performance Toilet Fill Valve). These help control how much water flows through the cartridge cleaning system so that your cleaner and water mixture doesn't just flow down the drain along with excess wasted water.

Love these but a bit expensive for just 2 refills.
