Chlorine Tablets

The chlorine tablet you choose controls how your pool holds sanitizer between service visits. Cheap big-box tablets dissolve too fast, spike your cyanuric acid, and leave you fighting algae by August. We stock the professional-grade stabilized trichlor our own service techs run in customer pools every week — brands chosen for consistent dissolve rates in North Texas heat. One 3-inch tablet per 5,000 gallons per week is the baseline; most DFW pools run 3-5 tablets weekly in summer. Order by 2 PM Central for same-day delivery, or pick up free at our Northlake store with a complimentary water test.

Chlorine Tablets questions

What size chlorine tablets should I buy?
3-inch trichlor tablets are the standard for nearly every residential inground pool — they dissolve over about a week and fit all standard chlorinators and floaters. 1-inch tablets are for spas and very small pools only.
What if my cyanuric acid (CYA) is already high?
Stop using trichlor — every tablet adds ~6 ppm CYA per 10,000 gallons. Switch to liquid chlorine or cal-hypo shock until CYA drops below 50. We carry both, and a free in-store water test will tell you exactly where you stand.

  • The March opening: test everything, brush, shock, then balance alkalinity, pH and calcium
  • Summer: testing two or three times a week, the weekly shock, and what to do after rain or a party
  • Fall leaves, and easing the chemistry down for winter
