8300 Flush 'n Sparkle Automatic Toilet Bowl Cleaning System with Bleach Cartridge

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

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.

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.
