Coleman SaluSpa Chlorine Tablets – Premium Spa Sanitizer
Our Coleman SaluSpa chlorine tablets are engineered specifically for inflatable hot tub systems, delivering consistent sanitization without the guesswork. Each tablet dissolves slowly in your spa's filter system, releasing a steady stream of chlorine that kills bacteria, prevents algae growth, and keeps water crystal clear between filter cycles.
We formulated these tablets to work seamlessly with SaluSpa's water chemistry, so you spend less time testing and adjusting. The slow-release design means fewer additions per week, and the compact size fits perfectly in floating dispensers or inline feeders. Whether you're maintaining your spa for daily relaxation or preparing for weekend guests, these tablets give you reliable protection without the harsh chemical smell that comes from shock treatments.
What makes these chlorine tablets different
How SaluSpa Chlorine Tablets Work
Chlorine tablets use a compressed trichlor formula that dissolves gradually when exposed to water flow in your spa’s filtration system. As each tablet breaks down over several days, it releases hypochlorous acid—the active sanitizing agent that destroys bacteria, viruses, and organic contaminants before they can multiply in warm spa water.
Unlike liquid chlorine or granular shock treatments that spike chlorine levels and dissipate quickly, our tablet formula maintains a steady 1.5-3.0 ppm free chlorine concentration throughout the week. This consistency prevents the chlorine demand spikes that lead to cloudy water and algae blooms. The stabilized formula includes cyanuric acid to shield active chlorine from UV breakdown, making these tablets especially effective in outdoor spa installations where sunlight would otherwise degrade sanitizer within hours.
Dosage and Application Instructions
For Coleman SaluSpa models with 177-290 gallon capacity, we recommend starting with one tablet in a floating dispenser or inline feeder. Test your water after 24 hours—you’re targeting 1.5-3.0 ppm free chlorine on your test strip. If levels fall below 1.5 ppm, add a second tablet or adjust your dispenser’s flow rate.
Dispenser Placement
Place floating dispensers in an area with good water circulation, away from the spa’s seating zones. Never place tablets directly in the filter housing or let them rest on the spa floor, as concentrated chlorine will damage vinyl and plastic surfaces. For inline feeders installed in the plumbing line, follow the manufacturer’s flow rate settings—typically one tablet per week for moderate use (3-5 sessions) or two tablets for heavy use (daily soaking).
Water Chemistry and Compatibility
Chlorine tablets work best when your spa’s pH sits between 7.2-7.6 and total alkalinity measures 80-120 ppm. Outside these ranges, chlorine becomes less effective—low pH causes rapid chlorine loss, while high pH reduces sanitizing power even when test strips show adequate chlorine levels.
Test your water chemistry twice per week using a reliable test kit or strips. If pH drifts high, add a small amount of pH decreaser before your next tablet. If alkalinity drops, dissolve alkalinity increaser in a bucket of spa water and pour it slowly around the perimeter. Our tablets are compatible with bromine systems, but we don’t recommend mixing sanitizers—choose one method and maintain it consistently.

Common Questions About SaluSpa Chlorine Tablets
For most Coleman SaluSpa models (177-290 gallons), start with one tablet in a floating dispenser or inline feeder. Test your water after 24 hours and adjust based on your free chlorine reading.
If you're below 1.5 ppm, add a second tablet or increase dispenser flow. Heavy use (daily soaking with multiple people) typically requires two tablets per week, while moderate use (3-4 sessions) stays balanced with one tablet. Always test twice weekly and adjust based on actual readings rather than a fixed schedule.
Yes, our chlorine tablets work in any inflatable or portable spa system that uses standard 1-inch trichlor tablets. The formulation is compatible with most brands' water chemistry requirements.
However, we've optimized the stabilizer ratio specifically for Coleman SaluSpa's filter flow rates and water volumes. If you're using a different brand, start with our recommended dosage and adjust based on your test results. Always follow your spa manufacturer's water capacity guidelines when calculating initial tablet quantity.
Yes, shock treatment every 1-2 weeks is essential even with regular tablet use. Chlorine tablets maintain baseline sanitization, but they don't oxidize dissolved organics from body oils, lotions, and cosmetics that accumulate over time.
Shocking breaks down these contaminants and eliminates chloramines that cause cloudy water and odor. Remove floating dispensers before adding shock, wait 15 minutes, then return them. The combination of steady tablet chlorination and periodic shocking keeps water exceptionally clear between drain-and-refill cycles.
A strong chlorine odor actually indicates too little free chlorine, not too much. That smell comes from chloramines—compounds that form when chlorine binds to nitrogen from sweat and urine.
Test your free chlorine level first. If it's below 1.5 ppm, add another tablet to bring levels up. If chlorine reads normal but odor persists, shock the spa with non-chlorine oxidizer to break the chloramine bonds. Once cleared, maintain proper tablet levels to prevent chloramine buildup from recurring.
When stored properly in the original sealed container, our chlorine tablets maintain full potency for 3-5 years. Keep the container tightly closed in a cool, dry location away from direct sunlight and moisture.
Never store near other pool chemicals, especially calcium hypochlorite shock, as contact between incompatible chemicals can produce dangerous reactions. If tablets develop a strong ammonia smell or crumble easily, they've absorbed moisture and should be replaced. Always check the manufacture date on the container and use oldest inventory first.
No, never place tablets directly in the filter housing or let them rest on the spa floor. Concentrated chlorine in direct contact with vinyl, plastic, or filter media causes permanent damage including bleaching, cracking, and deterioration.
Always use a floating dispenser or inline feeder designed for tablet distribution. These devices release chlorine gradually through controlled water flow, protecting your spa surfaces while maintaining proper sanitization. Place floating dispensers in areas with good circulation, away from seating zones where concentrated chlorine could irritate skin.
Trichlor tablets dissolve slowly over 5-7 days, maintaining steady chlorine levels with minimal effort. Granular chlorine dissolves immediately, causing chlorine spikes followed by rapid decline as it dissipates.
Tablets contain stabilizer (cyanuric acid) to resist UV breakdown, making them ideal for outdoor spas. Granular chlorine has no stabilizer and burns off quickly in sunlight. For routine maintenance, tablets provide more consistent results. Reserve granular chlorine for shock treatments when you need to raise levels quickly or oxidize heavy organic loads after parties or storms.
