Fluidmaster 8300 Flush 'n Sparkle Automatic Toilet Bowl Cleaning System with Bleach Cartridge, 1 Count (Pack of 1) ( Packaging May Vary)

What an easy hook up. Took me 3 minutes per toilet to install these units. They wok perfectly when you flush the toilet. Allows the bleach to coat and sit in the bowl to help with cleaning and sanitizing. I used my hot tub chlorine tests strips to measure the amount of chlorine in the bowl after a flush and it read 3 PPM’s which is ideal for sanitizing. Some people state in the reviews it had a huge chlorine sent. Thats really dependent upon your nose. lol. I didn’t notice a severe smell of chlorine. It was subtle Love these units. Keeps the bowl fresh. I still do a deep clean as needed and for sure once a week but these help between cleanings. Love them.

I have these installed on all three toilets in my house. Each toilet has a different type of flushing mechanism but the Flush 'n Sparkle installed easily on all of them in a minute or so. Most importantly, the product works. Toilets stay clean for months. I find that the cartridges last longer than the prescribed three months; I guess it depends on how often you flush. I'm happy about that because it helps control the cost. You may notice a slight chlorine smell, which doesn't bother me, but I thought I'd mention it.

This really does keep biofilms from forming on the submerged parts of the bowl. Only the water going into the bowl from the bottom ends up with bleach in it, so the upper, non-submerged parts of the bowl never get treated. You can decide if that's import to you. This unit installs between the toilet flush valve and the overflow tube in the toilet tank. That means a few things: 1) Installation involves opening the tank and routing some tubes, via pushing tubes onto nipples. It's pretty simple. 2) The bleachy water goes right into the bowl, never sitting in the tank degrading the rubber parts. That's a good thing. 3) Water from the flush valve now takes a longer path to get from the flush valve to the overflow tube to the bowl. That means that the bowl will refill more slowly compared to the tank filling and turning off the flush valve. That means that the water level in the bowl is likely to be lower after this unit is installed. That may be a bad thing for some users. A little math shows that the amount of bleach introduced into a septic tank is small compared to something like doing laundry with bleach. Certainly, we've seen no problems with our septic, even after using this product for a while.

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 Amazon 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.

I purchased this product in December, but didn't get around to trying it out until last week. I noticed right away the fumes were fairly strong but I thought it might dilute or calm down in a few days so I just kept the bathroom door shut with the fan on. I installed this in the bathroom across the hall from my bedroom where I work from home. Yesterday on my 30 minute lunch break, I left my bedroom door open on accident and someone in my family used the bathroom and didn't close the door all the way a few minutes after I went on my lunch break. When I came back from my 30 minute lunch break, my bedroom was so filled with fumes that my eyes hurt, my chest hurt, and I was coughing a little after 15 minutes of being in my room. I don't have the greatest sense of smell and I have allergies so it took me a few to realize what was bothering me. I opened the bedroom window and put on my fan to clear the bedroom out, took 3 showers scrubbing myself with rough cleaning rags to finally stop smelling like the bleach, although my hair still smells whenever I move my hair(shaking my head or scratching it, because my scalp itches too). I slept last night with my head near the open window. Thank goodness I did, because I woke up with my lungs still bothering me and my stomach hurting a bit, if I had left the window closed I'm nervous that I might not have woken up. I worked for a couple of hours but apparently the corner my desk is in did not air out enough, because my lungs started burning and my nostrils started hurting. I am currently sitting in my other bathroom with the shower on giving myself a steam treatment per advice from Poison Control, when I breathe deeply and exhale I taste chemicals on my tongue and my lungs, nostrils, and stomach are still bothering me. I am going to wash everything soft in my room, I think the fabrics are holding in the smell. But please be aware that ONLY 30 MINUTES OF COLLECTED FUMES has caused me all these problems. Ps. I have stomach issues and a low flow toilet so I while I knew there would be some fumes from the product, I was willing to try anything to avoid having to scrub the bowl all the time, plus most reviews said the fumes were minimal. The product did help keep the bowl clean for the week it was installed.

I am writing a review of three toilet cleaning systems I've bought here on amazon: Fluidmaster : Uses a cartridge containing a chlorine based tablet. Cartridge is not meant to be refilled. Chlorine odor noticeable in the bathroom. Cartridge can be modified (I used a dremel) so it is easily refilled. NeverScrub : Uses a cartridge containing a chlorine based crystal. Cartridge is not meant to be refilled. Chlorine odor noticeable in the bathroom. Kaboom : Does not use a cartridge. Bromine tablet refill inserts directly by unscrewing a cap. No odor noticeable in the bathroom. All three of these systems work the same way and all are really easy to install. All of them put a toilet cleaning chemical (tablets or crystals) in-line between the water fill valve and the toilet bowl fill pipe. All of them prevent the chemical from getting into the tank water (so there is no damage to the plastic parts in the tank). All sell refills for their systems. All keep the toilet bowl equally clean for about 1-3 months depending on how often it is flushed. Amazon also sells Pool/Spa Cleaning Chlorine and Bromine tablets, which as far as I can tell do just as good a job keeping the toilets clean as the refills but at a fraction of the cost. I have tried all of the following, each of which provide enough tablets to keep all the toilets in the house clean for 10 years and they are all very cheap: Kem-Tek 177 : The tablets fit well in the dremel-tool modified Fluidmaster cartridges. The tablets fit well in the Kaboom. The bathroom has a slight chlorine odor. Spa-Kem 267 : The tablets are too large to fit in the Fluidmaster cartridges. The tablets fit well in the Kaboom. No odor. Tropi Clear : The tablets fit well in the dremel-tool modified Fluidmaster cartridges. The tablets fit well in the Kaboom. No odor. Chlorine and Bromine are fairly equal in cleaning ability. Chlorine has that chlorine odor. Bromine is broken down by sunlight. Which is why, on a sunny day, outdoor pools use chlorine. But at night, or indoors, or on a cloudy day, they use bromine since there is no smell. Summary. The Fluidmaster system works but the cartridges are expensive. To refill the cartridges easily requires a small modification with a dremel tool. The cartridge is too small for any tablets larger than 1 inch in diameter. The NeverScrub system also works but the cartridges are expensive. What I am using is the Kaboom system with the bromine tablets (either the Tropi Clear or the Spa-Kem 267 ) as they have no odor and clean just as well as the chlorine tablets.

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!

This item works! It helps to break up water chemicals enough that they don't leave the "black water ring"

Too expensive - specially the refill, but works like wonder. This is not suitable for use in Indian Flush system as the overflow pipe is usually not available and I had to modify the same to get it working.

Muy buen producto facil de instalar

Bought two one for upstairs and one downstairs all the water runs though the tablets and helps keep the toilet clean. This is not a replacement for cleaning your toilet, you still need to clean it.

This kit is not readily available in Canada, but fortunately Amazon vendors sell it at a reasonable markup (considering it is shipped from the USA). It's an excellent automatic toilet cleaning system as it does not damage the rubber seals in your tank with chlorine (my Toto tank actually has an explicit warning stating not to use chlorine cleaners). It "splices" inline with fill hose so that the bleach solution bypasses the tank altogether (via the overflow tube) and fills your bowl after each flush while the tank is refilling. Installation is very simple, and the bracket is plastic so you can trim it to fit your tank if necessary. Ensure your tank lid seats fully to reduce flushing and filling noise. It functions as intended but I cannot assess effectiveness yet - I am hoping it either stops or slows the growth of the pink bacteria ring. There is a faint chlorine smell when you first lift the lid, but nothing too offensive IMO. The water level in my bowl has not changed. 3 month update: True to their word, the original chlorine tablets have completely dissolved after 3 months. This is on the primary toilet for two adults. I have not had to clean my toilet for the same period, and there is no pink bacterial growth whatsoever. This is an excellent upgrade as I was cleaning our toilet every 2-3 weeks due to the ring of pink bacteria. Refills: The replacement cartridges are not readily available in Canada but you can replace the tablets yourself with 1" tablets. To gain access, you can pry the bottom cap up off the cartridge with a folding utility knife and tap or pull the cap off. The original cartridge contains three 26x16mm (ie 1”) tablets and each weighs 11-12g (~34g net weight). The tablets contain DCDMH, boric acid and chlorine per the package label. However, the SDS for the refills indicate that the tablets used to contain 7-13% chlorine (89415-87-2), 40-70% BCDMH (16079-88-2) and 15-40% DCDMH (118-52-5). Fluidmaster likely originally used this chlorine-bromine blend because pure chlorine may be too acidic and/or odorous, but switched to chlorine only tablets due to costs? Regardless, for cheap refills, I purchased Azur Spa bromo tabs (~$50/1.8kg or 60c each). These tablets are 30x18mm (1.2") and weigh 20g. To fit these into the cleaner, cut the "lid" off the cartridge, remove the foam piece, and drop three tablets directly into the holder (instead of refilling the cartridge) - see photos. You now have 60g of bromine (compared to 34g of chlorine) that should last longer, be less acidic and smell less. Flow has not been restricted and there does not appear to be any downsides to this, but I will provide an update if that changes. Hope this helps.

Great product, keeps the toilet clean a longer period of time. However, the bleach refills are very expensive, twice the price, compared to the blue refills. And currently only one seller has them.
