How long it lasts
Flush Frog holds up to five standard 3-inch bromine (BCDMH) tablets. Load one tablet you buy separately; replace it when it’s gone. Each tablet can last up to one year depending on flush frequency and water conditions, providing up to approximately five years between full reloads. We do not sell tablets. Which cleaning tablets work with Flush Frog?

Three reasons

Fights rings every flush. Cleaner rides the bowl-refill path — where the ring forms.

Spares the tank reservoir. Unlike tank tablets, dosing is not sitting in standing tank water.

Fast install. Load, clip, connect — about three minutes, no tools.
How it works

Clip on the overflow pipe. Move the refill tube from the fill valve into Flush Frog. Every flush sends cleaner into the bowl — not into standing tank water.
Vs tank tablets

Tank tablets dissolve in the reservoir. Flush Frog uses the toilet’s existing bowl-refill stream instead — so cleaner goes where the ring forms.
Will it fit

Lift the lid. Do you see an overflow pipe and a refill tube you can redirect? Fits most standard 2-piece gravity toilets. Often no: pressure-assist, some one-piece, RV, some compact layouts. Don’t force tank parts. See if it fits.
What’s in the box

The clip-on dispenser only. No tablet. No tools. 1 Pack = one dispenser. 4 Pack = four dispensers.
Guarantee

30 days, including no-fit. If bowl maintenance isn’t easier, you get the purchase price back. Return shipping is not free.
How to install

About three minutes. No tools.

  1. Load one 3-inch bromine (BCDMH) tablet you buy separately (details above).
  2. Clip on the overflow pipe.
  3. Move the refill tube into Flush Frog.
  4. Lid on and flush once.
Prevention vs removal

Scrub what’s already there once. Then every flush fights it coming back. Prevention, not magic erase. Flush Frog is not a one-and-done stain eraser.
Shipping
