King Technology FROG Serene Mineral Cartridge
Four months of soft, fresh spa water.
The King Technology FROG Serene Mineral Cartridge (MPN 01-14-3812, SKU PST-01143812) drops a patented blend of silver and zinc minerals into your hot tub to kill bacteria naturally and hold your water crystal clear. Pair it with a FROG bromine cartridge and you cut your bromine use by up to 50%, so your spa smells cleaner and feels silkier. One prefilled cartridge runs a full four months, then you snap in a fresh one in under a minute.
Why PST Customers Pick This
Silver + Zinc Minerals
A patented FROG mineral blend uses silver and zinc to destroy bacteria and control algae the natural way, so your spa water stays fresh between drains.
Up To 50% Less Bromine
Run the mineral cartridge alongside a FROG bromine cartridge and the minerals do half the sanitizing work, cutting bromine consumption by up to 50%.
Silky, Balanced Water
Conditions your water for a softer, more comfortable soak while helping hold pH steady, so you spend less time chasing chemistry.
Fits Serene and @ease
Snaps into FROG Serene In-Line Systems and FROG @ease Floating Systems that use the reusable Serene mineral holder.
One-Minute Swap
Prefilled and sealed from the factory. Twist out the old cartridge, snap in the new one, and you are done in under a minute, no measuring or mixing.
Sized 150 To 600 Gallons
Rated for hot tubs and spas from 150 to 600 gallons, covering the vast majority of residential portable spas.
Handling Notice
This cartridge contains active sanitizing minerals. Do not open, crush, or empty the cartridge, and keep it away from children and pets. Do not mix its contents with other spa chemicals, shock, or bromine tablets outside the holder, since concentrated oxidizers can react and release fumes. Store it sealed in a cool, dry place and replace it after about four months or whenever you drain and refill the spa, because a spent mineral cartridge no longer sanitizes your water.

Frequently Asked Questions
How long does the FROG Serene mineral cartridge last?
The mineral cartridge lasts about four months, or until you drain and refill your spa, whichever comes first. Write the install date on the cartridge with a marker so you know when it is due. Once the minerals are spent the cartridge stops sanitizing, so replace it on schedule even if it still looks fine.
Does this cartridge replace bromine or chlorine entirely?
No. The FROG Serene mineral cartridge is designed to work with a FROG bromine cartridge, not instead of one. The minerals destroy bacteria so you need up to 50% less bromine, but you still run a low level of bromine for a complete sanitizing system. Running minerals alone will not keep spa water fully sanitized.
Will this fit my spa's FROG system?
This mineral cartridge fits FROG Serene In-Line Systems (the built-in cap-and-basket setup found on many Marquis, Caldera, and Hot Spring spas) and FROG @ease Floating Systems that use the reusable Serene mineral holder. It is rated for spas from 150 to 600 gallons. If your holder is stamped for the Serene mineral cartridge, this is the correct refill.
Can I install this myself?
Yes. No tools and no chemistry knowledge are needed. Open your FROG holder or in-line cap, twist out the old mineral cartridge, snap this prefilled one into place, and reset it in the water. The whole swap takes under a minute. Rinse your hands after handling and keep the cartridge sealed until you are ready to install it.
What is the difference between the mineral cartridge and the bromine cartridge?
The mineral cartridge (this item, 01-14-3812) holds silver and zinc minerals and lasts about four months. The bromine cartridge is a separate blue-capped cartridge that dispenses bromine and typically lasts two to four weeks depending on spa size and use. A complete FROG Serene setup runs both together in the same holder or in-line basket.
