Pool Chemical Safety: What You Need to Know (Without the Science Degree!)
Owning a pool is all about fun in the sun—but behind every crystal-clear splash is a lineup of hard-working pool chemicals keeping things clean and safe. To keep the good times rolling (and avoid any backyard chemistry experiments), here’s what you need to know about safely storing and mixing your pool chemicals.
What Pool Chemicals Can Be Stored Together?
Some pool chemicals play nicely with others—as long as they're sealed and stored properly:
-
pH increasers & decreasers (as long as they're in their original containers)
-
Stabilised Chlorine tablets and shock treatments (dry types only, stored separately but in the same cabinet is okay)
-
Algaecides, and clarifiers, (these are usually liquid and stable)
💡 Pro tip: Keep all chemicals in their original packaging with labels intact. Store them in a dry, well-ventilated cabinet away from direct sunlight and moisture.
⚠️ What Pool Chemicals Should You Never Mix?
Think of this as your “do not invite to the same party” list. Mixing the wrong chemicals can cause dangerous reactions like toxic gases, fires, or even explosions.
Here’s what you should never combine:
-
Chlorine and acid → This combo releases toxic chlorine gas (not the party vibe you’re going for).
-
Different types of chlorine (e.g., calcium hypochlorite + trichlor) → Can react violently.
-
Chlorine and ammonia-based products → Extremely hazardous.
If you ever smell a strong, sharp odour while handling chemicals—stop what you're doing, go up wind and remove yourself from the area immediately, then call 111 if necessary.
Can Pool Chemicals Be Stored Outside?
Short answer: Not ideal.
Long answer: Only if you have the right setup.
-
Avoid direct sunlight, heat, and moisture at all costs. Sun and water can break down chemicals or cause pressure to build in containers.
-
If you must store them outside, use a weatherproof, UV-resistant, ventilated storage box—preferably off the ground and out of reach of children and pets.
-
Bonus tip: Never store pool chemicals near gasoline, grills, or other flammables.
Summing it Up
Storing and handling pool chemicals safely doesn’t have to be scary. Just treat them with the same respect you would a strong cup of coffee—handle with care, don’t mix things blindly, and keep them out of the sun!
