Types of Stabilized Pool Chlorine
1” tablets, 3” tablets and sticks are the EXACT same chemical compound (Trichloro-S-Triazinetrione). So whether you call it a tablet, a puck, or a stick you are getting the exact same product. If you have an outdoor pool you need the stabilized chlorine and per pound the three inch chlorine tablets are the cheapest. Additionally, if you are using a chlorine feeder most are designed for the three inch chlorine tablets. So to get the most chlorine in your feeder at one time use the three inch tablets.
Why would you use the 1 inch tablets or chlorine sticks? This comes down to surface area; when you place the one inch tablets or sticks in your feeder they don’t line up as smoothly as the three inch tablets do. What this does is gives more surface area for water to erode the tablets – thus increasing the chlorine level more quickly. Another use for 1″ tablets is for chlorinating spas or very small pools, in which case a 3 inch chlorine tablet may be too large.
Types of Non-Stabilized Pool Chlorine
- It is only 10-15% available chlorine, and has more sodium than chlorine.
- It is the fastest acting due to the fact that it is pre-dissolved.
- It is un-stabilized or unprotected against the sun’s UV rays.
- It requires a specialized feeder or the pool owner to pour it into the pool.
- Pouring it directly into the pool will cause the chlorine to have peaks and valleys instead of having a steady safe level.
- Increases pH Levels dramatically, with a pH level of nearly 13.
One thing that all chlorine types have in common is that when they dissolve in water, they produce hypochlorous acid, which is the active ingredient in chlorine. Without it, contaminants, organic matter, viruses and pathogens begin to grow in any untreated body of water.
- Never mix different chlorine types together. They will react violently.
- Follow all label instructions when transporting, storing and using chlorine.
- Never allow dirt or any foreign substance or debris to contact chlorine.
- Keep chlorine tablets and granular in a cool, dry location, away from children.
- Never allow any other pool chemical to come in contact with chlorine.
So, in answer to the question: “What type of chlorine is right for me?”, consider your pool size and location. Outside of that I like to tell people, Buy the best chlorine at the lowest price, look for a low cost stick or tablet, from a company you like, and you’ll be fine.
Enjoy your Pool!
