Review: Works, without destroying your toilet - With experience over the years trying many different products, I've found that the only toilet cleaning solutions that are effective are those where the cleaning solution actually passes through the flush system (i.e., through the holes around the rim). The types that just clip onto the edge of the bowl are cute, but ineffective at actually keeping the toilet clean. There are many products sold that go in the tank which are effective at cleaning, however, they are harmful to the internal components and cause premature failure that can lead to leaks, and possibly property damage. The Fluidmaster system cleans effectively, without causing any damage to the toilet components. Its design is simple, yet genius. It consists of a small unit that connects onto the refill line, between the fill value and refill tube. The unit accepts a replaceable bleach cartridge and is completely sealed. When the toilet is flushed, water passes through the cleaning system, directly into the refill tube. This water passes through the flush holes and into the bowl, allowing the cleaning solution to be evenly distributed without any of the solution entering the tank. With this system clean water from the tank is used to flush, followed by the water with cleaning solution as the toilet refills. They claim that the bleach cartridges last approximately 3 months and I imagine that depends upon the amount of use. Unlike the bleach tablets you put directly in the tank which will continue to dissolve even without use (and thus the bleach content gets stronger and stronger), the Fluidmaster cartridges only get used when the toilet is flushed. This is by far the best cleaning system I've seen. It's simple, affordable, and effective. If you hate constantly scrubbing toilets, you may want to get this. We tried it in one of our toilets and it worked so well we bought three more. Oh, and if you're worried about remembering to change the cartridges, Fluidmaster has a website where you can sign up for reminders (and I'm sure they'll be more than happy to sell you the refills as well.) You can also get these on desertcart Subscribe and Save at a good price. That's what I did, so when they show up, I know it's time to change them. Also, as a side note, I did try buying chlorine tablets and using them instead of buying the replacement cartridges, as many others have done. While this option may be slightly less expensive, I've found that not to be a good option for several reasons. First, the chlorine smell is unbearable, even if I used only 1 tablet instead of two. Using bromine tablets would probably be better for that issue. Secondly, the chlorine tablets continue dissolving inside the cleaning system, even when the toilet is not used much. I had put 1 tablet in one of the toilets that we do not use much and after a week or so I flushed it and the smell was at toxic levels. I removed the cartridge to inspect and it had mostly dissolved and the fumes nearly killed me. The Fluidmaster refills do not seem to have this problem, as I've inspected all 4 of our toilets regularly while using them over the past year and find that those that are not used much stay intact, while those used more often dissolve faster. This is better as they remain effective for much longer in most of our toilets and I only have to replace the ones that are used more every 2-3 months. I'm not sure what's different about the tablets in the refill cartridges, but I've found it better to just buy them less often than trying to keep up with the chlorine tablets. I can say that our toilets do stay much cleaner using this system, so it has been worth the investment.
Review: Very Easy to Install--Works Great! - I just bought this Fluidmaster cleaning system to replace an older system I had that uses pellets. Although that system was a bit cheaper to run, it was hard to dispense the pellets without touching them--whereas the Fluidmaster cleaning compound comes in a sealed cartridge. This system is VERY easy to install and works great--even though I was attaching it to a non-Fluidmaster toilet valve. Here are a few things to note based on many of the reviews I read: I HAVE A NON-FLUIDMASTER TANK VALVE AND THIS CLEANING SYSTEM WAS VERY EASY TO INSTALL! 1) You have to make sure to TURN OFF THE WATER VALVE TO THE TOILET BEFORE YOU BEGIN! If you try to change ANY toilet tank part with the water still on, you WILL get sprayed. (FYI--the water shut-off valve will be at the end of the pipe coming out of the wall below the toilet tank. it will have a short hose attached to it that runs up from the valve into the bottom of the tank that connects to the tank valve. Turn it to the right to turn it off and to the left to open it.) 2) There are only two connection points for this system: A) The tube that is attached to the upper part of box is the "intake" connection. (You'll know it's the UPPER part of the box because this is also where the cleaning cartridge is installed.) This "intake" tube is attached to the nipple on the top of your tank valve--that long, skinny plastic tower that brings in the water that fills the tank and also controls how much water comes in.) B) The tube that is attached to the bottom of box is the outflow tube. It takes the water that has entered the box through the intake tube, that then flows through the cleaning cartridge, and comes out here to go into the toilet overflow tower. This second tube actually comes out of the bottom of the cleaning box and then is re-routed so it goes back up long the side of the box so it is ready to be attached to the overflow tower in the middle of the toilet tank. Without this re-routing, the outflow tube from the box would essentially be floating free in the tank. 3) It is possible that in order to ship the cleaning systems, that outflow tube that descends for the bottom of the cleaning box is drawn too tight and might be slightly pinched. To alleviate that, just pull slightly on the left side of the of that outflow tube. That left side of the tube will move down a little adding some length to the tube and eliminating any pinched areas in the tube. 4) Slip the cleaning box on to the back edge of the tank so that it is a couple inches to the right of overflow tube (that tower in the middle of the tank). 5) Attach the the free end of the cleaning box's upper intake tube to the nipple on the top of the tank valve (that long skinny tower that lets the water into the tank--the one you turned OFF the water to in step 1). (You might need to cut the rubber intake tube from the cleaning with a pair of scissors to get the length right, but once you've attached the box to the back of the tank, pull the intake tube toward toward the intake tower nipple and snip off the extra tubing. If you snip off too much, just push the cleaning box toward the intake valve tower to make up for that extra space. THIS CONNECTION WITH THE INTAKE TOWER NIPPLE WILL BE TIGHT!! IF IT WASN'T TIGHT, IT WOULD LEAK!! IT MIGHT TAKE SOME FORCE TO GET IT ON, BUT THIS IS NOT PECULIAR TO THE FLUIDMASTER SYSTEM--ANY SYSTEM WITH A TUBE--AND ALL OF THESE HAVE TUBES--WILL REQUIRE SOME FORCE. IF YOU CANNOT GET IT ON, REMOVE THE WHOLE SYSTEM FROM YOUR TOILET, TAKE IT TO A FLAT, HARD SURFACE, AND ZAP THE END OF THE RUBBER TUBE WITH SOME HOT AIR FROM A HAIR DRYER--ONLY A FEW SECONDS, OTHERWISE YOU Will MELT THE RUBBER AND HAVE TO CUT THAT MELTED PART OFF! 6) Once you have attached the box's intake tube to the water valve tower nipple, connect the box's outflow tube to the tank's overflow tower with the included clip (or, if you have another type of overflow tube other than Fluidmaster, you can attach that tube accordingly.) Don't forget to turn the stare to the toilet back on!

## Questions & Answers

**Q: What is the difference betwee the Fluid Master Flush and Sparkle 8100 and 8300P8 models?**
A: 8300 is bleach only.  The description for 8100 blue cartridge says that in addition to the bleach, it is a Surfactant-based cleaning agent which reduces spread of viruses and bacteria.  The 8200 green cartridge is for septic tanks where bleach shouldn't be used.

**Q: Is the cartridge supposed to sit above or below the water line of the tank, or doees it matter?**
A: Thank you for your question concerning 8300P8 Flush “n” Sparkle Bleach Kit. The housing unit that the cartridge is inserted into is a sealed container and can get wet. The housing unit in most cases is located above the water line however it can be partially submerged. For additional questions on any Fluidmaster product please contact us at your earliest convenience. Fluidmaster’s Technical Service Department is available Monday through Friday from 5:30 AM through 5:00 PM Pacific Standard Time. Contact options include: Chat www.fluidmaster.com/support E-Mail techsupport@fluidmaster.com and Toll Free 800-631-2011.

**Q: Is this product safe for septic systems?  I mean, will it kill all the good bacteria in the septic tank?**
A: It's fine. We use bleach in way higher quantity in the washing machine with no issues. Your septic tank is a few hundred gallons of poo. That little amount will do nothing.

**Q: Is the cartride supposed to sit above or below the water line of the tank, or does it even matter?**
A: It does not matter. The cartridge gets water directly from the toilet float valve. There are two tubes to the cartridge system, input and output, water is pushed into the cartridge system circles around the cleaning tablet and out through the output line into the flapper and to the toilet bowl.

### ⭐⭐⭐⭐ Best cleaner I've ever had!! Works like a charm!!
*by A***M on August 4, 2017*

Have always used the drop in tank tablet cleaners but decided to give this one a try. Was fairly easy to set up and install although very much depends on the kind of system you have in your tank so research that first. I had to use a different hose for part of it because the one provided was just too short based on how I had to hang the system and where the connections were. After figuring all that out which only took a few minutes everything worked perfectly. Some have said they smell chlorine a lot from this unit, I myself did not at first. After a few days you sometimes might catch a very slight hint of it for a second or two and that's it. Nothing horrible whatsoever. It works like a charm and kept the Bowl cleaner than anything else I had ever tried. The only downside I can see from this, depending on your point of view, is the cost. You do have to replace the filter and it is fairly inexpensive but maybe not over time. As many have mentioned there is a way to alter the unit so that you can use much cheaper replacement tablets without having to get a whole new filter. It is solely because of this reason that I give it 4 stars instead of 5.
