Chlorine
Chlorine is the backbone of pool sanitation. It kills bacteria and prevents algae growth. Chlorine comes in various forms: liquid, powder, and tablets. When added to water, it forms hypochlorous acid, which targets harmful microorganisms. If you notice a strong "pool smell," it might mean there's not enough chlorine!
Shock
Shocking your pool is like giving it a deep clean. It involves adding a large dose of chlorine or a chlorine-free alternative to eliminate chloramines—those pesky byproducts that can irritate eyes and skin. Regular shocking, usually once a week, ensures your pool water stays fresh and clear.
Bromine
An alternative to chlorine, bromine is often used in hot tubs due to its effectiveness at higher pH levels. It's a bit gentler on the skin and eyes, making it a popular choice for those sensitive to chlorine.
Cyanuric Acid
Think of cyanuric acid as sunscreen for your chlorine. It protects chlorine from being broken down by the sun’s UV rays. However, too much can hinder chlorine's effectiveness, so keep it balanced.
Calcium Chloride
Calcium chloride is essential for maintaining the right level of calcium hardness in your pool. Without it, water can become corrosive, damaging tiles and metal parts. Aim for a calcium hardness level between 200 and 400 ppm.
Algaecide
Algaecide helps prevent algae from taking over your pool. Often copper-based, it acts as a barrier, keeping your pool clear and inviting. Add it after shocking the pool to fend off algae growth.
Clarifier
Clarifiers are like a pool’s best friend when it comes to clarity. They bind tiny particles together, making them easier for the filter to catch. This keeps your pool water sparkling and inviting.
Flocculant
Flocculants are similar to clarifiers but work differently. They clump particles together and sink them to the pool floor. You'll need to vacuum these out, but it’s worth it for that crystal-clear look.
Each of these chemicals plays a unique role in maintaining your pool's health. In the next section, we'll explore how to use sanitizers, oxidizers, water balancers, and specialty chemicals to keep your pool in top shape.

What Pool Chemicals Do I Need?
Maintaining the perfect pool requires a mix of essential chemicals. Understanding what pool chemicals you need and how they work will keep your water sparkling and safe for everyone to enjoy. Let's break down the key categories and their roles.
Sanitizers
Sanitizers are the frontline defense against bacteria and algae in your pool. The most common types are chlorine and bromine.
Chlorine: Available in tablets, liquid, or granular form, chlorine is the go-to choice for most pool owners. It effectively kills bacteria and keeps your pool water safe and clean. The ideal range for Free Available Chlorine is between 1.0 and 4.0 parts per million (ppm) to ensure safety and cleanliness.
Bromine: A great alternative for those with sensitive skin, bromine is often used in hot tubs because it remains stable in warm water. However, it's important to note that bromine and chlorine cannot be used together.
Trichlor and Sodium Dichlor: Both are forms of stabilized chlorine. Trichlor tablets are great for everyday use, dissolving slowly to release chlorine steadily. Dichlor is usually in granular form and is useful for quickly raising chlorine and cyanuric acid levels in outdoor pools.
Oxidizers
Oxidizers, commonly known as pool shock, are used to give your pool a deep clean by eliminating chloramines and other contaminants.
Calcium Hypochlorite: Known as cal-hypo, this is a powerful oxidizer that quickly raises chlorine levels to kill bacteria and algae. It's best to use cal-hypo when your pool's pH level is low since it can increase pH.
Chlorine-Free Shock: Also called potassium monopersulfate, this shock option is ideal when you need a quick, residue-free clean. It allows you to swim just 15 minutes after application and is compatible with bromine sanitizers.
Water Balancers
Water balancers are crucial to maintaining the overall health of your pool. They help adjust the pH, alkalinity, and calcium hardness levels.
pH Increaser & Decreaser: pH balance is key. If it's too low (below 7.2 ppm), use a pH increaser like pH Up. If it's too high (above 7.6 ppm), a pH decreaser can help bring it down.
Alkalinity Increaser: Works with pH to stabilize your pool water. If total alkalinity falls below 80 ppm, use this increaser to bring it back up.
Calcium Hardness Increaser: This increases the calcium hardness in your pool water to prevent damage to your pool surfaces. Keep levels between 200 and 400 ppm.
Specialty Chemicals
While these aren't needed all the time, specialty chemicals are invaluable for troubleshooting specific pool issues.
Algaecides: These are your go-to for preventing and eliminating algae. They come in copper-based or non-metallic forms.
Clarifiers & Flocculants: Both help clean your pool water by clumping small particles together. Clarifiers make them easier to filter out, while flocculants cause them to sink for vacuuming.
Enzymes: Products like Pool Perfect break down oils and other non-living organic matter, keeping your water clean and clear.
Phosphate Removers: Use these to reduce phosphates in your pool water, as phosphates are a main food source for algae. Products like PhosFree are effective in breaking down phosphates.
With these chemicals on hand, you can maintain the perfect balance in your pool, ensuring a safe and enjoyable swimming experience for everyone. In the next section, we'll explain how to maintain this balance effectively.

How to Maintain Pool Chemical Balance
Maintaining the right chemical balance in your pool is essential for keeping the water clean and safe for swimming. Here's how you can achieve and maintain the perfect balance:
Testing
Regular testing of your pool water is crucial. You can use test kits or test strips to check the levels of chemicals like chlorine, pH, alkalinity, calcium hardness, and cyanuric acid. Aim to test your water at least once a week, or more frequently if your pool gets a lot of use. If you prefer professional help, consider bringing a water sample to your local Lakeside Pool Service location for a free, 10-point water analysis.
Adjusting
Once you have your test results, it's time to make adjustments:
Chlorine Levels: Keep Free Available Chlorine between 1.0 and 4.0 parts per million (ppm) to ensure your pool water is safe and clean. Use chlorine tablets for steady maintenance and shock treatments for a quick boost when needed, especially after heavy use or a rainstorm.
pH Levels: The ideal pH range for pool water is between 7.4 and 7.6. Use pH Up or pH Down products to adjust the pH level. High pH can cause cloudy water and scaling, while low pH can cause skin irritation and corrosion.
Total Alkalinity: This should be maintained between 80 and 120 ppm. Use an alkalinity increaser to stabilize pH and prevent fluctuations.
Calcium Hardness: Aim for a calcium hardness level between 200 and 400 ppm. Use a calcium hardness increaser if levels fall below this range to prevent damage to your pool surfaces and equipment.
Safety Tips
Handling pool chemicals requires care:
Always read and follow the manufacturer’s instructions on product labels. Wear rubber gloves and protective eyewear. Never mix different chemicals together, as this can cause dangerous reactions. Add chemicals to water, not the other way around. This prevents contamination and dangerous reactions. Keep all pool chemicals out of reach of children and pets.
Storage
Proper storage of pool chemicals is essential for safety and effectiveness:
Store chemicals in a cool, dry, and well-ventilated area.
Keep them in their original containers with labels intact.
Never return spilled material to its original container.
Follow local regulations for the disposal of unused chemicals.
By regularly testing, carefully adjusting, and safely storing your pool chemicals, you can maintain a clean and safe environment for swimming. Now that you know how to keep your pool's chemical balance in check, let's address some frequently asked questions about pool chemicals.
