Description
Three Silver SmartChlor Refills for Your FROG @ease In-Line Spa
The FROG @ease In-Line SmartChlor Replacement Chlorine Cartridge 3 Pack gives you three silver, pre-filled SmartChlor refills for hot tubs up to 600 gallons with a built-in FROG @ease In-Line holder, including Hot Spring Hot Spot models and FROG cartridge ready Hot Spring Freeflow spas. Paired with the blue FROG @ease Mineral Cartridge, each refill holds free chlorine at a low 0.5–1.0 ppm with up to 75% less chlorine than the ANSI minimum for hot tubs.
At about 3–4 weeks per cartridge, a 3-pack covers roughly two to three months of soaking. It is the easy middle ground: enough SmartChlor refills to stay ahead of every swap without stocking a shelf.
Always used together: pair SmartChlor with the FROG @ease In-Line Mineral Cartridge, the blue cartridge that goes in the top slot and is replaced every 4 months. FROG @ease needs both cartridges to sanitize your water.
A Two- to Three-Month SmartChlor Refill Supply
Each silver SmartChlor cartridge typically lasts about 3–4 weeks in an average 400-gallon hot tub, so three cartridges carry you through roughly 9–12 weeks of normal use. When the test strip says a cartridge is out, the next one is already in the cabinet.
Pair each swap with one dose of FROG Maintain non-chlorine shock and your whole sanitizing routine becomes a once-a-month calendar reminder.
Low, Steady Chlorine for Hot Tubs Up to 600 Gallons
SmartChlor is a slow-dissolving, self-regulating chlorine. It builds a chlorine reserve in the water that converts to free chlorine only when the water needs it, so levels stay at 0.5–1.0 ppm instead of spiking and crashing like granular chlorine.
The adjustable dial covers spas from 200 to 600 gallons. Set it once for your tub's volume and leave it, with no measuring and no daily dosing.
Fresh Mineral Water With Less Chlorine Smell
FROG minerals do part of the sanitizing work, which is why SmartChlor can run so low. Together they make what FROG calls Fresh Mineral Water: clear, soft-feeling water with less chlorine odor and less wear on swimsuits and covers.
SmartChlor is formulated to work with FROG minerals. Keep an active blue FROG @ease Mineral Cartridge in the top slot of the holder.
No Cyanuric Acid Build-Up Between Drains
Dichlor granules add cyanuric acid (CYA) with every dose, and in a small, hot body of water it builds up quickly, leading to cloudy, itchy water and earlier drains. SmartChlor adds no CYA, so your water stays easier to manage between fill-ups.

How to Replace Your SmartChlor Cartridge
- Balance the water first: Bring Total Alkalinity to 80–120 ppm, then pH to 7.2–7.6, and keep Total Hardness at 150–250 ppm. SmartChlor works best and lasts longest in balanced water.
- Turn the jets off: Never open the In-Line cap while the jets are running. Lift the cap, then push the holder down and turn it 1/8 turn counterclockwise to pull it out.
- Remove the spent cartridge: Drain the water out of the old silver cartridge to confirm it is empty, then discard it in the trash or recycle it where available. Do not refill or reuse it.
- Unwrap and set one new cartridge: Take one cartridge from the pack, remove the shrink wrap, hold the bottom and turn the dial to the setting for your hot tub size (see the chart below). Leave the rest sealed.
- Snap it into the holder: Snap the silver SmartChlor cartridge into the bottom slot marked "Bromine or SmartChlor," lining up the indentation with the raised area on the holder. The blue mineral cartridge stays in the top slot marked "Minerals" at setting #6.
- Lock the holder and replace the cap: Line up the holder arrow with the system arrow, push down past the tabs and turn clockwise until it stops. Tug up gently to confirm it is locked.
- Shock with FROG Maintain: Add one dose of FROG Maintain non-chlorine shock each time you change the SmartChlor cartridge, or once a month.
- Test and track: Test weekly with FROG @ease Test Strips. Replace the cartridge when the top tab is lighter than the SmartChlor Out Indicator on the bottle, and replace the mineral cartridge every 4 months.
SmartChlor Dial Setting Chart

Compatibility Notes
Before You Buy
- Made for hot tubs with the built-in FROG @ease In-Line cartridge holder (a cap on the spa's top rim) and for the FROG @ease Filter Basket System. FROG lists these models for the @ease In-Line system: Artesian Elite and Artesian Island (optional on Island Elite and South Seas), Marquis Crown (optional on Elite, Vector and Celebrity), Caldera Vacanza and Hot Spring Hot Spot. Hot Spring Freeflow Collection spas are also FROG cartridge ready.
- Not for FROG @ease Floating System dispensers, @ease+ floating systems or swim spa dispensers, which use different cartridges.
- Must be used with an active FROG @ease Mineral Cartridge. SmartChlor alone will not keep the water sanitized.
- Do not use dichlor shock. It adds cyanuric acid, which reduces SmartChlor's effectiveness. Use FROG Maintain non-chlorine shock.
- Switching from bromine? Drain and refill before starting FROG @ease. Switching from dichlor? You can convert without draining if cyanuric acid is below 80 ppm.
- Other test strips misread the SmartChlor reserve as high total chlorine. Use FROG @ease Test Strips.

Why Choose the FROG @ease SmartChlor 3 Pack
The 3-pack is a popular, practical way to keep a FROG @ease In-Line spa on schedule: three silver refills, one reorder every couple of months, and low-chlorine water that feels softer and smells less like chlorine.

Frequently Asked Questions
Does this 3 pack fit Hot Spring hot tubs?
Yes, if your Hot Spring spa has the built-in FROG @ease In-Line holder. FROG lists the Hot Spring Hot Spot models, and Hot Spring Freeflow Collection spas are FROG cartridge ready. Look for the cap on the top rim of the spa.
What dial setting do I use for my hot tub size?
Match the dial to your gallons. In the In-Line holder: 1 for 200–250, 2 for 251–300, 3 for 301–450 and 4 for 451–600. Use the same setting for each cartridge in the pack unless your test strips tell you otherwise.
Do I still need the mineral cartridge?
Yes. These are SmartChlor refills only. Keep an active blue FROG @ease Mineral Cartridge in the top slot. A 3-pack usually runs out before the mineral cartridge's 4-month change.
Should I shock each time I open a new cartridge from the pack?
Yes. FROG recommends shocking with FROG Maintain non-chlorine shock right before you put in a new SmartChlor cartridge, about once a month. That clears contaminants as the old cartridge's reserve runs down, so the new one starts fresh.
How long does a 3 pack of FROG @ease SmartChlor cartridges last?
About 9–12 weeks at typical use. Each cartridge lasts about 3–4 weeks in an average 400-gallon hot tub used by two people two or three times a week with about 4 hours of filtration a day. Larger tubs, more bathers and higher dial settings use cartridges faster.
Is this 3 pack for spas up to 600 gallons?
Yes. The dial settings cover hot tubs from 200 to 600 gallons in both the In-Line holder and the Filter Basket System. Set each cartridge to match your spa's water volume.
How many mineral cartridges go with a 3 pack of SmartChlor?
One blue mineral cartridge lasts 4 months, which is longer than a 3-pack usually lasts. Most owners use four to six SmartChlor cartridges per mineral cartridge, so plan on a 3-pack plus one or two more cartridges per mineral cycle.
Why choose a 3 pack over single cartridges?
A 3-pack covers roughly 2–3 months, so you reorder about once a season instead of every few weeks, and the next cartridge is ready the moment the test strip says the current one is out.
What size hot tub will FROG @ease work in?
FROG says hot tubs from 150 to 600 gallons are a fit for FROG @ease. The In-Line dial chart covers 200 to 600 gallons on settings 1–4, so for a spa under 200 gallons, start on setting 1 and let your FROG @ease Test Strips guide any change.
How do FROG @ease Test Strips work?
They check pH, Total Alkalinity and Total Hardness, plus a SmartChlor Out Indicator on the top pad. Dip the strip, remove it with the pads facing up, shake once and compare it with the chart on the bottle. If the SmartChlor color is darker than the bottle label, the cartridge is still working. If it is lighter, swap in the next cartridge.
How long do FROG @ease Test Strips stay good?
FROG says its @ease Test Strips last about 2 years, so check the expiration date on the bottle, especially if you buy strips well ahead of time.
Why does my hot tub keep drifting high on pH and alkalinity?
FROG notes that jet aeration tends to push pH and Total Alkalinity up in hot tubs. When they run high, SmartChlor is less effective, so test regularly and bring alkalinity into 80–120 ppm before adjusting pH to 7.2–7.6.
What should I check before turning the dial up?
FROG suggests three checks: the blue mineral cartridge has been replaced within the last 4 months, the water is balanced, and the test strip shows the SmartChlor color darker than the bottle's out indicator. If all three are true, turn the dial up one setting.
How often should I test the water?
FROG recommends testing with FROG @ease Test Strips at least once a week. That quick check confirms your water balance and tells you when it is time to open the next cartridge in the pack.
Is FROG @ease more expensive than dichlor?
FROG says SmartChlor costs slightly more than dichlor but less than other systems. Owners make up some of that by shocking only once a month and using up to 75% less chlorine.
Safety Notes
Handle With Care
- Turn the jets off before opening the In-Line cap. Water can be forced out under pressure.
- SmartChlor is an oxidizer and is corrosive in concentrated form. Avoid contact with skin, eyes and clothing, and do not breathe the dust. Wear gloves and eye protection when handling a damaged cartridge.
- Never mix with other chemicals, especially other chlorine products, bleach, ammonia or alkalis. Keep cartridges dry until use, since contact with water outside the spa can release toxic gas.
- Store unused cartridges sealed in a cool, dry, well-ventilated place below 125°F, away from combustible materials, and out of reach of children and pets.
- Drain spent cartridges before disposal and do not reuse them. Read the full label and the Safety Data Sheet below before use.
