How to Choose the Right Chlorine Pucks for Your Spa or Hot Tub
How to Choose the Right Chlorine Pucks for Your Spa or Hot Tub
Keeping your hot tub water clean is one of the most important parts of taking care of your spa. If the water isn't clean, it can look cloudy, smell bad, or even cause skin problems. This is why many hot tub owners use chlorine pucks to keep their water fresh and safe.
Chlorine pucks help kill bacteria and keep the water clear. But not all chlorine pucks are the same. If you want your hot tub to stay in good shape, it's important to choose the right one.
At Canada Hot Tubs, we carry top-quality chlorine tablets that are made for hot tubs. In this guide, we'll explain what chlorine pucks are, why they matter, and how to choose the best kind for your spa.
What Are Chlorine Pucks?
Chlorine pucks are small, round tablets that dissolve slowly in water. As they dissolve, they release chlorine that helps clean the water. This kills germs, bacteria, and other things that can grow in warm water.
People like using chlorine pucks because they are:
- Easy to use
- Long-lasting
- Less messy than liquid chlorine
- Good at keeping water safe over time
Instead of putting chlorine in the hot tub every day, you can add a puck and let it work for several days.
1. Pick the Right Size for Your Spa
Hot tubs come in different sizes, and so do chlorine pucks. Some pucks are made for big pools and are too strong for hot tubs. These are usually 3 inches wide and release a lot of chlorine.
For hot tubs, it's best to use 1-inch chlorine pucks. These are made just for smaller spas and dissolve slower in hot water. Using pool-sized pucks in a spa can make the water too strong and can irritate your skin and eyes.
At Canada Hot Tubs, we only sell chlorine tablets that are safe and gentle for hot tubs of all sizes.
2. Make Sure the Pucks Are Stabilized
If your hot tub is outside, the sun can break down chlorine quickly. This means you would have to use more chlorine more often. To solve this, look for stabilized chlorine tablets. These tablets have a special ingredient that protects the chlorine from sunlight. All the chlorine pucks we offer at Canada Hot Tubs are stabilized. This means they last longer and save you money over time.
3. Use Tablets Made for Hot Tubs
Not every chlorine puck is made for spa use. Some are made for large swimming pools and are too strong for hot tubs. These pool tablets can cause damage to your hot tub and even bleach the surface.
Make sure you use spa-specific chlorine capsules. They are made to work better in hot water and won't harm your spa. Our tablets at Canada Hot Tubs are safe for use in all major hot tub brands.
4. Avoid Extra Additives
Some chlorine pucks come with extras like water clarifiers or algaecides. These may sound helpful, but they can sometimes cause problems in hot tubs. For example, they can make the water foam or clog the filters.
We recommend choosing pure chlorine capsules without any extras. This keeps the water clean without causing other issues.
5. Always Choose Good Quality
It can be tempting to buy reasonable tablets, but this can lead to problems. Low-quality tablets might not dissolve properly, or they might leave behind white residue. They can also cause damage to your hot tub over time.
At Canada Hot Tubs, we only carry trusted brands like SpaBoss and Dazzle. These are high-quality products that work well and protect your hot tub and your skin.

FAQs: Chlorine Tablets for Hot Tubs
1. How often should I add chlorine tablets to my spa?
Most 1-inch tablets last about 3 to 7 days. Check your chlorine levels every few days and add a new tablet when needed.
2. Can I use pool chlorine tablets in my hot tub?
No. Pool tablets are too big and strong. They can damage your hot tub and make the water too harsh. Always use spa-safe 1-inch chlorine pucks.
3. What chlorine level should I keep in my hot tub?
Try to keep the chlorine level between 3 and 5 parts per million (ppm). This is strong enough to kill bacteria but still safe for people.
4. Where should I put the chlorine puck?
Use a floating dispenser or the built-in tablet feeder if your spa has one. Don't drop tablets straight into the water, as this can damage the tub's surface.
5. Are chlorine tablets safe for kids?
Yes, as long as the chlorine level is correct and the tablets are used properly. Always check water levels before letting kids use the hot tub.
