A Weekly Pool Maintenance Calendar

← Understanding Water Chemistry Completing Your First Year →

Most maintenance calendars online are written for climates with a true off-season; a Houston pool needs a rhythm built around year-round use instead. Unincorporated Harris and Montgomery County lots around Tomball and Magnolia often run on septic and private well systems, so equipment pads, plumbing runs, and excavation are planned around those systems during the site evaluation, not discovered mid-dig.

Twice a Week, Minimum

Test free chlorine, pH, and alkalinity twice weekly as a baseline, more often during heavy rain, pool parties, or the hottest stretch of summer when chlorine demand climbs fastest.

Skim the surface and empty skimmer baskets on the same schedule; debris sitting in a basket for days raises chlorine demand and can clog circulation at the worst possible time.

Monthly and Quarterly Tasks

Check calcium hardness, cyanuric acid (stabilizer), and total dissolved solids monthly; these drift slowly and do not need twice-weekly testing but do need checking before they become a visible problem.

Backwash or clean the filter on a schedule driven by pressure gauge readings (typically when pressure rises 8-10 psi above the clean baseline) rather than a fixed calendar date, and inspect pump, heater, and salt cell (if applicable) quarterly for wear.
