To keep the toilet water looking beautiful, we use special "Sea Freshness" flush tablets. They're dropped directly into the tank and gradually dissolve, disinfecting and tinting the water blue. They also clean hard-to-reach areas, providing hygienic freshness with every flush, and preventing limescale and rust deposits. Depending on how often you flush, one tablet lasts 5-7 days!
There are also "Pine Freshness" tablets, but they produce a color reminiscent of "urine," so we don't use them.
