BIOION Toilet Flush Block: FAQ

How long does the block last?
One block will last approximately 2 months under normal usage (around 10 flushes per day). Actual lifespan may vary depending on water quality and temperature.
Is the blue color a disinfectant agent?
No. The blue color is purely a visual indicator so you know the block is active. The actual cleaning and disinfecting agents are distinct from the dye.
Does it cause stains in the toilet bowl?
No, it does not stain the toilet bowl. The color dissolves completely with every flush and leaves no residue or permanent marks on porcelain.
How can we know when it's time to replace it?
When the water stops turning blue, it’s time for a replacement. As the color fades from deep blue to clear, the active cleaning ingredients are running out.
Does it harm the microorganisms in the toilet's wastewater system?
No. When used as directed, the formula is septic-safe and biodegradable. It will not disrupt the beneficial microorganisms in your wastewater or septic system.
