Pool FROG Bac Pac Cartridge - 3 pack

Bac Pac 3 Pack: Weeks of Clear, Low-Chlorine Water With Spares Ready

A Pool FROG pool stays clear, fresh and comfortable because the minerals and a low, steady dose of chlorine work as a team. This 3 pack keeps the chlorine side of that team stocked, giving you weeks of clean water with up to 50% less chlorine* and no scramble when a pac runs out.

Every Bac Pac is prefilled and sealed, so there's nothing to measure, scoop or touch. Swap one in, set the dial once, and the pool largely takes care of itself, leaving you more time to swim and less time testing and dosing.

The box holds three 2.2 lb trichlor pacs for the Pool FROG Model 5400 in-ground or Model 6100 above-ground cycler. At the typical 2–3 weeks per pac, they cover about 6–9 weeks, which is a good fit for opening the pool or a shorter season.

Before You Buy

• Fits the Pool FROG Model 5400 in-ground cycler (in-line or off-line) for pools of 7,000–40,000 gallons.
• Fits the Pool FROG Model 6100 above-ground cycler for pools up to 25,000 gallons.
• Sits inside the Pool FROG Mineral Reservoir, which is replaced every 6 months or one season.
• Does not fit Pool FROG XL PRO (it uses the Pac 540C), Flippin' FROG, FROG Leap, FROG Pool Tender or any hot tub system.
• Use only Bac Pacs in the cycler. Never load loose trichlor, fast-dissolving tablets, bleach or calcium hypochlorite.

How long will a 3 pack last?

About 6 to 9 weeks in one cycler, since each pac typically runs 2 to 3 weeks. Heat and heavy swimming shorten that.

Is the 3 pack cheaper than buying singles?

Not per pac. Three singles and one 3 pack ring up the same total here, so the reason to choose it is fewer trips back to reorder.

Is this the same 3 pack other retailers sell as Pool FROG Bac Pac Replacement Chlorine Cartridges, 3 Pack?

Yes. That marketplace 3 pack and this listing both carry UPC 722906005223 and contain three standard 01-03-5880 pacs.

How do I find the right dial setting with a new pac?

Start from the chart in your cycler's manual, then test free chlorine every day for the first week. Turn the dial up ½ if it's below 0.5 ppm and down ½ if it's above 1.0.

My chlorine reading is above 3.0 ppm. What should I do?

Pull the pac out until the level falls back to 1.0 ppm, put it back, and lower the dial. Too much trichlor can bleach a liner around the return.

Do I put in FROG BAM or the Bac Pac first?

BAM goes in first. It circulates through the cycler, and once the water in the cycler runs clear you insert the Bac Pac.

How often should I shock with a Pool FROG?

About every other week, or as needed. FROG prefers non-chlorine shock since low chlorine is the goal, but chlorine shock is fine. Add it straight to the pool, never the skimmer.

What water balance should I keep?

Alkalinity 80–120 ppm, pH 7.2–7.8, hardness 200–400 ppm and stabilizer 20–80 ppm. Adjust alkalinity first and wait 8–12 hours between products.

Will trichlor pacs raise my stabilizer?

Gradually, because trichlor contains cyanuric acid. Test it a few times a season; above 80 ppm, partly drain and refill.

How big a pool can a Model 6100 handle?

Up to 25,000 gallons. For an in-ground pool up to 40,000 gallons, the Model 5400 is the matching cycler.

Do I still need a new Mineral Reservoir?

Yes, every 6 months or one season, whichever comes first. Bac Pacs supply only the chlorine; the reservoir supplies the minerals.

Should I adjust anything after a big storm?

Retest chlorine and pH. Heavy rain dilutes the water and can drop chlorine below 0.5 ppm, and the pac may need a slightly higher setting for a day or two.

What should I test with?

Any strip that reads free chlorine in the 0.5–1.0 ppm range, plus pH and alkalinity. FROG Test Strips are designed for that range.

Is a chlorine smell normal when I open the cycler?

Yes. Trichlor gives off fumes inside the closed cycler, so stand back for a moment after removing the cap before reaching in.

Where should I keep the two spare pacs?

Leave them in their caps on a shelf in a shed or garage that stays dry and airy. Chlorine fumes corrode metal, so keep tools and bikes elsewhere, and keep children and pets out.

Handle With Care

• Danger, corrosive: the label warns it causes irreversible eye damage and skin burns, may be fatal if inhaled or absorbed through skin, and is harmful if swallowed. Don't breathe the dust, wear eye protection and gloves, and wash thoroughly after handling.
• It is a strong oxidizer. Mixing it with other chemicals, especially calcium hypochlorite, other chlorine types, acids or organic matter, can cause fire, explosion or toxic gas. Never put anything but Bac Pacs in the cycler.
• Never add other chlorine or shock through the skimmer; add them directly to the pool. Don't inhale fumes from the cycler or pac.
• Don't install the cycler in copper pipe when using Bac Pacs. Don't exceed the cycler's 50 psi or 104°F limits.
• First aid (label): for eyes, hold open and rinse slowly with water for 15–20 minutes, removing contact lenses after the first 5 minutes. For skin, remove contaminated clothing and rinse for 15–20 minutes. If swallowed, call a poison control center or doctor right away.
• Store sealed pacs in a cool, dry, well-ventilated place away from heat, open flame, children, pets and anything metal that can rust. Keep them apart from other pool chemicals.
• The label notes it is toxic to fish and aquatic organisms, and that some settling may occur during shipment.
• Read the Bac Pac label, your cycler's manual and the Safety Data Sheet before use.
