SpaPure Brominating Tabs, 2 lb Bromine Tablets for Spas and Hot Tubs
Hot water sanitizing that keeps working.
SpaPure Brominating Tabs (MPN C002510-CS20B2, PST SKU PST-SPA2510CS20B2) is a 2 pound bottle of 1 inch, slow dissolving bromine tablets built for spas and hot tubs. Chlorine does the job in a cool pool, but hot and heavily used water is where bromine pulls ahead, because it keeps sanitizing regardless of conditions, stays effective across the pH range your spa actually drifts through, and runs a lower odor than chlorine maintenance. Load the tabs into a floating dispenser or an inline brominator, hold a 2 to 4 ppm bromine residual, and each tablet feeds down over days instead of dumping its whole load at once.
Why PST Customers Pick This
Works At Any pH
Unlike chlorine, bromine stays effective regardless of where your pH sits. You are not chasing a narrow window to keep the sanitizer working, which is the single biggest reason bromine wins in spas.
Built For Hot, Busy Water
Warm, heavily used water burns through sanitizer fast. Bromine holds a working residual in exactly those conditions, so a full hot tub on a Saturday night does not strip your protection by Sunday.
Slow Dissolving, Long Lasting
The 1 inch compressed tablets release evenly over days rather than flashing off in one hit. That means fewer trips to the spa side and a residual that holds between checks.
Lower Odor Than Chlorine
Bromine maintenance carries noticeably less of the sharp smell people associate with chlorine, which matters most on indoor spas and covered hot tubs where the air has nowhere to go.
Fits Standard Spa Feeders
The 1 inch tab size drops straight into most floating dispensers and inline brominators. A dispenser is the recommended way to run these so the feed rate stays controlled.
Made In The USA
SpaPure is a Haviland Consumer Products brand, manufactured in the United States with more than 55 years of pool and spa chemistry behind the line.
Chemical Handling
Never mix Brominating Tabs with chlorine tablets, other sanitizers, or any other spa chemical, in a dispenser or anywhere else. Combining halogen products can generate heat and toxic gas and has started fires in dry storage. Use a clean, dedicated dispenser, keep the bottle sealed in a cool dry place away from other chemicals, and read the full product label and Safety Data Sheet before handling.

Frequently Asked Questions
Why run bromine instead of chlorine in a spa?
Three reasons, and they all come from the fact that a spa is hot, small, and heavily loaded. Bromine keeps sanitizing regardless of water conditions, it stays effective regardless of the pH level rather than falling off when pH drifts high, and it carries a lower odor than chlorine maintenance. Chlorine is a fine spa sanitizer, bromine is the better one for warm, heavily used water.
How many tablets does my spa need?
Enough to hold 2 to 4 ppm of bromine, then adjust from there. The actual tablet count varies with your spa make and model, how often it gets used, and the residual you want to carry, so treat the first fill as a calibration run. Start on the low side, test after 24 hours, and add tabs to the dispenser until the reading holds steady in that 2 to 4 ppm band.
Which SpaPure Brominating Tabs size should I order?
This listing is the 2 lb bottle, part C002510-CS20B2. SpaPure runs the same 1 inch tablet in a smaller 1.5 lb bottle and a larger 4 lb bottle, and the chemistry is identical across all three, only the bottle size changes. Pick the 2 lb if you run a standard residential spa year round, and step up to the 4 lb if you are covering a larger spa or a heavily used one.
Do I need a dispenser, or can I drop tabs straight in the water?
Use a dispenser. A floating dispenser or an inline brominator is the recommended method, and it is what keeps the feed rate controlled and the residual steady. Loose tablets sitting on an acrylic shell or against a filter can bleach and damage the surface as they dissolve, so keep them contained. Adding tabs to a dispenser is straightforward homeowner work, no tools and no service call required.
How do I start a fresh spa fill on bromine?
Build the bank first, then feed it. Start the spa with SpaPure Brom Bank (PST SKU PST-SPA3402CS40P) or SpaPure Sodium Bromide (PST SKU PST-SPA3731CS20X2) to establish the bromide reserve, then introduce Brominating Tabs to bring the spa up to a 2 to 4 ppm bromine reading and hold it there. Skipping the bank step is why a fresh fill can feel slow to come up on bromine.

Let customers speak for us
Exactly what I needed.
Perfect fit ! Thanks for the great quality product and fast shipping!
Fit perfect
after 2 other suppliers failed to understand the part PST Pool Suppliers filled my order and took time to explained the part to me to insure it was what I wanted and I received it in short time
Fast delivery and exactly what i needed!
This was a game changer to be able to purchase the piece that was broken on our pool vacuum and not have to buy an entire new unit when it was still working fine otherwise. Website was easy to navigate and secure for payment. Shipping took a little longer than what was offered on another website, but otherwise our experience was great and our vacuum is uo and running again thankfully!!
The part came and was exact match and so far has been working great . Just wish you guys offered different shipping options because it took a week to get it .
Spa came with this. But swim portion did not. Now it does. Highly recommend for remote control.
The bulb was lost in transit and PST reached out proactively to ask if I wanted a replacement shipped out!
Helpful and responsive when USPS was delayed.
part was an exact fit for my old spa, price was great thanks
Fast shipping and great customer support. I appreciate all of the help in getting my spa up and working.
The cord worked perfectly when I upgraded my older Balboa spa and pump.
I had a leak in which water was leaking out to the waste line. I could hear the water trickling in the waste line. The spider gasket in this kit resolved the issue.
Shipping and delivery were quick. Would definitely order again from PST.
Fit perfectly and works great.
