Liquid chlorine is better for most pools.

Yes, liquid is the smarter choice for everyday sanitation. Tablets (trichlor) are convenient but come with a hidden cost: they add cyanuric acid (stabilizer) that builds up over time. Too much stabilizer and your chlorine stops working. Liquid chlorine adds nothing but chlorine, so you keep full control.

Tablets win on ease—drop one in a floater and forget it for a week. But if you have a small pool or don’t mind pouring in a jug every few days, liquid is cheaper per dose and lets you manage your chemistry without surprises. Shocking? Use liquid anyway. Tablets are best for vacation mode or low-maintenance setups.

Your pool will thank you, and so will your wallet.
