Owning a swimming pool in Karachi can be a luxury—but maintaining it in the city’s hot and humid climate is a serious responsibility. Without proper chemical balance, pools can quickly become breeding grounds for algae, bacteria, and cloudy water.
In this post, we’ll walk you through how to safely and effectively use chlorine, aluminium sulphate, and algaecide for swimming pools in Karachi, ensuring a clean, safe, and refreshing swim every time.
Understanding Karachi’s Climate and Its Impact on Pool Water
Karachi experiences high temperatures, humidity, and dust exposure, all of which can:
- Increase chlorine breakdown due to UV rays
- Promote algae growth
- Make pool water cloudy or hazy
This means regular chemical balancing is more important here than in cooler or less dusty regions.
Chlorine for Swimming Pool in Karachi: Your First Line of Defense
Chlorine is essential to kill bacteria, viruses, and algae. However, Karachi’s heat speeds up chlorine evaporation, especially if you’re using unstabilized chlorine.
How to Use Chlorine Safely:
- Use stabilized chlorine (dichlor or trichlor) to reduce UV loss.
- Maintain chlorine levels between 1–3 ppm at all times.
- Test the water 2–3 times a week, especially during peak summer.
- Store chlorine in a cool, dry place away from direct sunlight.
Tip: Using a chlorine floater helps distribute the chemical evenly without direct handling.
Aluminium Sulphate for Swimming Pool in Karachi: Clearing Cloudy Water
If your pool looks milky or dull, it might be time for aluminium sulphate—a flocculant that binds fine particles and sinks them to the bottom for vacuuming.
How to Use Aluminium Sulphate:
- Dissolve 100–150 grams per 10,000 liters of water.
- Spread evenly over the pool surface.
- Let it sit undisturbed for 12–24 hours to settle debris.
- Vacuum the settled particles without disturbing them.
Safety Note: Never mix aluminium sulphate directly with chlorine—it should be added separately and only when necessary.
Algaecide for Swimming Pool in Karachi: Preventing and Controlling Algae
Karachi’s humidity encourages algae blooms, especially after rain or if chlorine levels drop.
How to Use Algaecide:
- Use a non-copper algaecide for regular maintenance.
- Add according to the product label, usually once a week.
- Shock your pool with chlorine before applying algaecide if algae is already present.
- Run your filter continuously for 24 hours post-application.
Pro tip: Look for algaecide for swimming pool in Karachi that’s formulated for high temperatures and hard water.
General Safety Tips for Handling Pool Chemicals
- Always wear gloves and goggles when handling any chemical.
- Store chemicals in original containers, away from children and pets.
- Never mix chemicals together—especially chlorine and acids, which can release toxic fumes.
- Add chemicals to water, never the other way around.
