Which cleaning tablets work with Flush Frog?

Flush Frog is designed around a compatible 3-inch BCDMH bromine tablet. The cleaning tablet is sold separately; Flush Frog sells the dispenser.

Where to buy compatible 3-inch Bromine (BCDMH) tablets

Standard 3-inch pool/spa bromine tablets (BCDMH) fit Flush Frog. Cleaning tablets are sold separately. Always confirm the product label identifies the tablet as bromine/BCDMH, follow the manufacturer’s handling instructions, and never mix toilet-cleaning chemicals.

Retailer links are provided for convenience; tablets are sold separately. Availability and formulations can change, so verify size and BCDMH chemistry before buying.

What does BCDMH mean?

BCDMH is shorthand for bromochloro-5,5-dimethylhydantoin, a solid halogen-releasing chemistry used in some water-treatment products. You do not need to memorize the name. You do need to read the product label.

What to check before buying a tablet

  • The product is the compatible size and form specified for the dispenser.
  • The label permits the intended use and provides clear handling instructions.
  • You understand its storage, ventilation, first-aid, and disposal warnings.
  • You are not combining it with another toilet-cleaning chemical.

How long will a tablet last?

Tablet life is a system result, not just a tablet specification. It can change with how often the toilet is flushed, how much refill water passes through the dispenser, water temperature and chemistry, tablet formulation, and how the dispenser is loaded.

For that reason, treat exact calendar-life claims as estimates rather than guarantees. Replace the tablet when it is depleted and follow the tablet manufacturer’s instructions.

Can I load more than one?

The dispenser has capacity for multiple compatible tablets, but more chemistry is not automatically better. Start with the product instructions, do not exceed the intended loading, and evaluate your actual toilet rather than chasing maximum concentration.

The most important chemistry rule

Never mix toilet-cleaning products. Acids, chlorine-releasing cleaners, and other oxidizing or reducing chemicals can react dangerously when combined. Do not pour another cleaner into the tank, bowl, or dispenser unless the product labels explicitly permit that combination.

What about septic systems?

The Flush Frog dispenser itself does not make a cleaning chemistry “septic-safe.” If you have a septic system, follow the tablet manufacturer’s label, your septic-system guidance, and applicable local recommendations. If a label does not clearly address your intended use, choose a product that does or ask the manufacturer.

Why the tablet is separate

The dispenser is reusable hardware. Keeping the chemistry separate means you can read and choose the cleaning product’s own label rather than relying on a vague proprietary refill cartridge.
