Why pool shock matters for Pecan Square pools
Shocking isn't about "more chlorine" — it's about rapidly oxidizing organics (sweat, oils, urine, algae) that normal chlorine can't keep up with. Using the wrong shock makes problems worse: cal-hypo raises calcium hardness (bad in DFW hard-water areas), dichlor raises cyanuric (bad if you're already high). Picking the right shock for your current water is the difference between a clear pool and a chemical bill that keeps climbing.
Brand new municipal infrastructure. The primary focus is managing the high pH spikes that occur naturally during the first 12 months of new plaster curing.
Pool Shock questions from Pecan Square customers
Which shock should I use for my Pecan Square pool?▾
On Pecan Square municipal water, cal-hypo is the most economical choice — your starting calcium is usually 200-300 ppm, well under the scaling threshold, so the extra calcium from cal-hypo shock won't cause problems unless you're on a cartridge filter. Most Pecan Square pools are plaster or pebble — finishes that show staining fast if chemistry slips.
My Pecan Square pool turned green — what should I buy right now?▾
Depends how green. Hazy/light green: double-dose cal-hypo (2 lb per 10,000 gal) at dusk, brush the whole pool, run pump 24 hours, re-shock next day. Dark green / swamp: triple shock (3 lb cal-hypo per 10,000 gal) + phosphate remover + polyquat algaecide — expect 3-5 days to clarify. Black algae: separate playbook — call us. We stock everything you need and can deliver same-day to Pecan Square; or book our Green-to-Clean service and we'll handle it end-to-end.
How often should Pecan Square pools shock during summer?▾
Weekly during peak season (June-August), plus an extra shock after any heavy rain and after any pool party. DFW heat and UV burn through free chlorine fast, so even a "routine" shock cycle keeps chloramines down and algae from getting a foothold. If you're on weekly service with us, we include the shock — no separate order needed.
How fast can you get shock to Pecan Square?▾
Same-day if you order by 2 PM Central on a weekday. We run daily routes through Pecan Square (76247) and neighboring Northlake and Justin. If your pool's already turning, call (469) 455-1054 and we can sometimes get a driver out within 2 hours.
How long after shocking can I swim?▾
Cal-hypo and dichlor: 24 hours, or until free chlorine drops below 5 ppm. Non-chlorine shock (potassium monopersulfate): 15 minutes. Never enter a pool with free chlorine above 5 ppm — it's irritating and risks bleaching swimwear.
Cal-hypo vs dichlor vs non-chlorine — what's the difference?▾
Cal-hypo: unstabilized, raises calcium hardness, classic weekly shock. Dichlor: stabilized (adds cyanuric acid), use sparingly to avoid CYA buildup. Non-chlorine (potassium monopersulfate): oxidizes contaminants without adding chlorine, 15-min swim window, great for parties.
