Why Above Ground Pool Chlorine Tablets Are Necessary
From my experience, using chlorine tablets in my above ground pool has been a game-changer for maintaining clean and safe water. These tablets slowly release chlorine over time, which helps keep the water consistently sanitized without the need for constant manual dosing. This steady release means I don’t have to worry about sudden spikes or drops in chlorine levels, making pool maintenance much easier.
Another reason I find chlorine tablets necessary is their convenience. They dissolve slowly, allowing me to add them to a floating dispenser or skimmer basket and let them do their work. This saves me time and effort compared to liquid chlorine or powder, which require more frequent application. Plus, they help prevent algae growth and kill harmful bacteria, so my pool stays crystal clear and safe for swimming.
Ultimately, chlorine tablets give me peace of mind knowing that my pool water is balanced and protected. They are an essential part of my routine to enjoy a refreshing swim without worrying about water quality issues.
My Buying Guides on Above Ground Pool Chlorine Tablets
When I first started maintaining my above ground pool, I quickly realized that choosing the right chlorine tablets made a huge difference in keeping the water clean, clear, and safe. Over time, I’ve learned what to look for and what to avoid. Here’s my personal guide to help you pick the best chlorine tablets for your above ground pool.
1. Understand the Purpose of Chlorine Tablets
Chlorine tablets are designed to sanitize your pool water by killing bacteria, algae, and other harmful microorganisms. I found that using tablets instead of liquid chlorine or granules offers a slow, steady release of chlorine, which helps maintain consistent water chemistry without frequent dosing.
2. Choose the Right Type of Chlorine Tablets
There are mainly two types of chlorine tablets I’ve encountered:
- Trichlor (Trichloro-s-triazinetrione): These are stabilized tablets that contain cyanuric acid, which protects chlorine from being broken down by sunlight. I prefer these for outdoor pools because they last longer in the sun.
- Dichlor (Sodium dichloro-s-triazinetrione): These tablets are also stabilized and dissolve faster than trichlor, but they add less cyanuric acid. I sometimes use dichlor for quick shock treatments or smaller pools.
Avoid using unstabilized chlorine tablets like calcium hypochlorite unless you know exactly how to manage pool chemistry, as they can cause rapid chlorine loss.
3. Check the Tablet Size and Concentration
Tablets come in different sizes, usually 1-inch or 3-inch. I use 3-inch tablets in my floating dispenser or chlorinator because they last longer and are more convenient. If you have a smaller pool or a feeder system designed for 1-inch tablets, make sure to buy the correct size. Also, check the concentration of available chlorine on the label—higher concentration means more effective sanitation but requires careful dosing.
4. Consider Stabilizer Content (Cyanuric Acid)
Since my pool is outdoors, I pay attention to the cyanuric acid (CYA) content in the tablets. CYA protects chlorine from UV degradation, so tablets with stabilizer help maintain chlorine levels longer in sunlight. However, too much CYA can reduce chlorine’s effectiveness, so I test my water regularly and balance accordingly.
5. Packaging and Storage
I always look for tablets that come in moisture-resistant containers with resealable lids. Chlorine tablets can degrade or clump if exposed to humidity. Proper storage ensures they stay effective and safe to handle. Also, keep them out of reach of children and pets.
6. Safety Precautions
Handling chlorine tablets requires care. I wear gloves and avoid mixing tablets with other chemicals. Never drop tablets directly into the pool skimmer or near the pool ladder to prevent concentrated chlorine burns or equipment damage.
7. Price and Brand Reputation
While I don’t always go for the cheapest option, I look for trusted brands with good reviews to ensure product quality and consistency. Sometimes spending a bit more upfront saves money by reducing algae outbreaks and chemical imbalances later.
8. Additional Tips
- Use a floating dispenser or automatic chlorinator to control tablet dissolution rate.
- Test your pool water regularly (chlorine, pH, alkalinity) to adjust tablet usage.
- Consider shock treatments occasionally to reset water balance.

Choosing the right chlorine tablets for your above ground pool can seem overwhelming at first, but by focusing on these key factors, I’ve been able to keep my pool sparkling clean all season long. Hopefully, my experience helps you make an informed decision!
