The goal is simple: pick the tablet size your hardware was built for, load enough for the trip, and leave the pool starting from a clean, balanced place. That approach works better than chasing the biggest bag or the most impressive label.
Quick comparison
| Pick | Best for | Why it fits | Watch out |
|---|---|---|---|
| Clorox Pool&Spa 6-Way 1-Inch Chlorinating Tablets (50 lb) | Standard 1-inch feeders | Common size that is easy to load and leave alone | Still depends on a clean feeder and balanced water |
| HTH 1-Inch Chlorinating Tablets (70 lb) | Standard 1-inch systems that need a larger supply | Same format with more reserve for the trip | Bulkier to store |
| DuraKleen 3-Inch Chlorine Tablets (100 lb) | 3-inch feeders and holders | Matches large tablet hardware already in use | Wrong size for 1-inch floaters |
| BioGuard SoftSwim Chlorinating Tablets 1-Inch (50 lb) | Regular weekly maintenance | Straightforward 1-inch option for an existing routine | No storage advantage for smaller spaces |
| Aquachem Chlorinating Tablets (1-Inch, 25 lb) | Small pools and tight storage | Smaller bag is easier to keep on hand | Less reserve for hot weather or heavier use |
The shortest way to choose is to start with the feeder size you already have, then decide how much reserve you want for the week.
Clorox Pool&Spa 6-Way 1-Inch Chlorinating Tablets (50 lb): Best standard 1-inch pick
Clorox Pool&Spa 6-Way 1-Inch Chlorinating Tablets (50 lb) is the easiest fit when your pool already runs a standard 1-inch floater or inline feeder. For a week away, that matters because you can leave the hardware alone and focus on the water itself instead of changing the setup right before you go.
This is the cleanest default for owners who want a familiar tablet format and a simple trip plan. If you have used 1-inch tablets before, this keeps the routine familiar. That is valuable when the pool is already working well and you only need it to stay steady while you are gone.
The limitation is the same one any tablet plan has: the bag cannot fix a feeder that is dirty, jammed, or set poorly. It also does not help much if the pool water already needs correction before the trip. Choose a different option if your hardware takes 3-inch tablets or if you want a smaller bag that is easier to store.
HTH 1-Inch Chlorinating Tablets (70 lb): Best larger reserve for standard 1-inch systems
HTH 1-Inch Chlorinating Tablets (70 lb) keeps the same familiar 1-inch format but gives you a larger supply to work from. That makes it a good fit for pool owners who already use tablets on a normal basis and want one bag that can cover the trip without feeling tight.
The strength of this pick is simple reserve. If your pool is exposed to strong sun, warm water, or a little extra use while you are away, having more tablets on hand gives you more room to set the feeder conservatively. It is a practical option for people who do not want to swap to a different size just for vacation week.
The trade-off is storage. A larger bag is less convenient if shelf space is already crowded. Choose something smaller if you only need a modest amount of product or if you are trying to keep the chemical shelf tidy.
DuraKleen 3-Inch Chlorine Tablets (100 lb): Best match for 3-inch feeders
DuraKleen 3-Inch Chlorine Tablets (100 lb) belongs in the 3-inch feeder lane and nowhere else. If your pool already uses a 3-inch feeder or a holder built for larger tablets, this is the type of tablet that fits the hardware you already own.
That makes it a clean choice for longer trips because it avoids the common mistake of buying tablets that do not match the feeder. When the tablet size and the hardware line up, the feeder is easier to set and easier to trust while you are gone.
The limitation is obvious: a 3-inch tablet is not a general-purpose buy for a 1-inch floater. Choose a different option if your feeder only accepts 1-inch tablets, or if you are still using a small portable setup that was never designed for the larger size.
BioGuard SoftSwim Chlorinating Tablets 1-Inch (50 lb): Best steady routine option
BioGuard SoftSwim Chlorinating Tablets 1-Inch (50 lb) is the straightforward choice for owners who already keep the pool on a regular 1-inch tablet routine. It is not trying to be clever. It is just a familiar format that fits standard feeders and keeps the maintenance pattern stable while you are away.
That makes it a good option if your pool is already dialed in and you want to keep the same rhythm for the week you will be gone. Some owners prefer that because it avoids changing brands, changing tablet size, or changing the way the feeder is loaded right before a trip.
The main limitation is that it does not offer a special storage advantage or a trip-specific shortcut. It is the steady option, not the compact one. Choose a different tablet if you need a smaller stash or if your feeder is built for 3-inch tablets instead.
Aquachem Chlorinating Tablets (1-Inch, 25 lb): Best smaller bag for tight storage
Aquachem Chlorinating Tablets (1-Inch, 25 lb) is the compact pick in this group. The smaller bag is easier to store and easier to keep around if you do not want a large chlorine supply sitting on the shelf after the trip.
This is a good match for small pools, short vacations, or owners who just want a lighter supply for the season. If the pool does not burn through tablets quickly, the smaller format can be the cleanest way to buy only what you need for the week.
The limitation is reserve. A 25 lb bag gives you less cushion if the weather turns hot, the pool sees more use, or the water tends to burn through chlorine faster than you expect. Choose a larger 1-inch option if the week is likely to be hard on the water.
How to set the dosing for a weeklong trip
The right tablet is only half the job. The other half is setting the feeder so it delivers a steady flow instead of dumping too much too soon or running dry before you get home.
Use this order:
- Start with clean, balanced water. Tablets are for keeping the pool steady, not for rescuing water that is already off.
- Clean the floater or feeder before you load it. A clogged feeder cannot do its job well, even if the tablet itself is the right size.
- Match the tablet size to the hardware. Use 1-inch tablets in 1-inch feeders and 3-inch tablets in 3-inch feeders.
- Load enough tablets for the trip, but do not treat a week away like a season-long shutdown.
- Set the opening conservatively at first. A week is long enough to need real output, but not so long that you want the feeder wide open from day one.
- Keep the pump schedule steady. Circulation has to move water past the feeder or the tablets cannot do their work evenly.
- Keep tablets dry and separate from other pool chemicals.
If the pool sits in full sun, gets splash-out, or usually burns through chlorine quickly, give the feeder a little more room. If the weather is mild and the pool is quiet, start on the tighter side and leave it there. The goal is steady output, not a fast dump.
When tablets are not enough
Tablets are a maintenance tool, not a reset button. If the water is cloudy, green, or badly out of line before you leave, handle that first. A weeklong vacation is not the moment to hope a tablet bag will solve a problem that already exists.
The same goes for weak circulation, a feeder that will not open properly, or a floater that does not move the way it should. In those cases, the better move is to fix the setup before the trip and then let tablets do the quiet work of holding the line while you are gone.
Final verdict
For most weeklong trips, the smartest buy is the tablet size that matches the feeder already in place. If you have a standard 1-inch system, Clorox Pool&Spa 6-Way 1-Inch Chlorinating Tablets (50 lb) is the easiest all-around pick, and HTH 1-Inch Chlorinating Tablets (70 lb) is the better choice if you want more reserve in the same format. If your hardware is built for 3-inch tablets, DuraKleen 3-Inch Chlorine Tablets (100 lb) is the clean match. If storage space matters more than reserve, Aquachem Chlorinating Tablets (1-Inch, 25 lb) keeps the supply compact. BioGuard SoftSwim Chlorinating Tablets 1-Inch (50 lb) is the steady routine option for owners who already live on a 1-inch tablet schedule.
The real win is not filling the feeder as much as possible. It is starting with balanced water, using the right tablet size, and setting the feeder to keep a steady stream going for the week you are away.
