King Technology FROG Serene Bromine Cartridge
Softer water, up to 50% less bromine.
The King Technology FROG Serene Bromine Cartridge (MPN 01-14-3824, SKU PST-01143824) is the pre-filled bromine refill that keeps your hot tub clear and sanitized with far less effort than loose tablets. It snaps into the FROG Serene holder alongside the mineral cartridge, so FROG minerals handle part of the work and you run up to 50% less bromine than a standard bromine spa. Bromine dissolves slowly and steadily in hot water, so your reading stays even and the water feels silky instead of harsh.
Why PST Customers Pick This
Steady Bromine Release
Pre-filled with 150 grams of bromine that dissolves gradually in hot water, so your sanitizer level holds even instead of spiking and crashing like hand-dosed tablets.
Up To 50% Less Bromine
Pairs with the FROG mineral cartridge, which destroys bacteria on its own, so you sanitize with roughly half the bromine of a standard bromine-only spa.
Softer, Clearer Water
The mineral-plus-low-bromine approach leaves water feeling silky and looking crystal clear, with far less of the heavy chemical odor bromine spas are known for.
Swaps In Under A Minute
Twist the holder open, drop in the fresh cartridge, twist it closed. No measuring, no test-and-add guesswork, no floating tablets to fish out.
Floating Or In-Line
The same 01-14-3824 cartridge fits both the FROG Serene floating holder and the FROG Serene in-line cap built into many spa plumbing systems.
Adjustable Dial Control
Set the release dial on the FROG holder to match your spa size and bather load, then let the cartridge meter bromine automatically between refills.
Handling Warning
This cartridge contains a concentrated bromine sanitizer. Handle it dry, never mix it with chlorine products, other spa chemicals, or any acid, and never pre-dissolve it in a bucket, mixing bromine with other chemicals can release toxic gas or cause a fire. Keep it sealed, cool, and out of reach of children and pets until you load it into the FROG holder, and wash your hands after handling.

Frequently Asked Questions
Does this bromine cartridge work in both the floating and the in-line FROG Serene system?
Yes. The 01-14-3824 bromine cartridge is the same part for both setups. It snaps into the FROG Serene floating holder that drifts in the water, and it also drops into the in-line cap that Marquis, Caldera, and Hot Springs (and others) build into the spa's plumbing at the factory. Same cartridge, either system.
Do I still need the FROG mineral cartridge, or is bromine enough on its own?
You need both for the system to work as designed. The mineral cartridge kills a portion of the bacteria on its own, which is exactly why you can run up to 50% less bromine. Running bromine alone gives up that benefit. The mineral cartridge lasts about four months (replace it when you drain and refill the spa), while this bromine cartridge is replaced every 2 to 4 weeks.
How long does one bromine cartridge last?
Plan on 2 to 4 weeks per cartridge. The exact life depends on your water volume, how many people use the spa, and how often. Set the dial on the FROG holder lower for a smaller or lightly used tub to stretch each cartridge, and higher for a large or heavily used one. Always keep bromine in your target range with a test strip.
How much bromine does this hold and what does the dial do?
Each cartridge is pre-filled with 150 grams of bromine. The adjustable dial on the FROG holder controls how much water flows past the cartridge, which sets how fast bromine releases. Dial it to match your spa size and bather load once, then let the cartridge meter the bromine for you between refills.
Can I set this up myself?
Yes, no tools required. Twist the FROG holder open, seat the fresh bromine cartridge next to the mineral cartridge, twist it closed, and set the dial. The whole swap takes under a minute. Handle the cartridge dry and never combine it with chlorine or other chemicals. Test your water after the first day and adjust the dial as needed.

Let customers speak for us
The process was smooth and lights arived as expected. Everything test out in good working order.
Needed to replace the control overlay on our Nordic Impulse hot tub, but could not find out the make or model number of the actual control panel on our tub. By taking measurements and photos or our actual control panel button positions and functions, I was able to narrow down the options. I ordered this overlay as the button positions seemed to be in the right positions, even though the overall size was smaller than the control panel. The overlay works, in that all buttons and functions are in the right place, and the overlay seems to have adhered well to the panel. It is not a perfect match, as it is smaller overall than it should be. But I am happy with the result and will buy an additional identical overlay as a backup in case this one, too, deteriorates at some point. Took a lot of detecting, but the result is successful!
This costume is legit. It has the sparkle, glittery sheen to it like the one used on screen! Very happy with it!!
Excellent service!
PST was great at communicating the status of my order throughout the various stages. I actually did encounter a shipment issue and they handled it without issue. I will be doing business again with them.

as described, fast shipping
My wife has RA and is always uncomfortable. Our hot tub heater failed and all the local shops were not able to assist until November. I was able to order an exact replacement part which was delivered within 3 days the hot tub was up and functioning in three days. I was very impressed with the quality and service.
Good quality just ordered wrong size and also need thicker cover
Fit perfectly, and fast shipping
Super fast shipping and reliable product !
I accidentally broke the original knob by tightening it too much. This was a perfect fit and works 100%. Fast delivery too!
Swapped out broken heater (lasted about 6 years) for this one. The instructions are for the electronics, not for the plumbing. You must get everything perfectly aligned or the plumbing may leak. I needed to loosen the electronics box to get the plumbing perfectly aligned. I have hot water again.
Great prices, fast shipping, great products
Haven't received yet but I'm sure it'll be great
