Weekly Pool Service for Southwest Houston Backyards

Hose water that starts at the top of the pH range

Through a Houston summer, evaporation keeps the hose going into the pool, and on the City of Houston Main System that water is not neutral. The city's 2025 water quality report put its average pH at 7.8, the upper edge of the 7.0 to 7.8 range the CDC recommends for pools. Water features push the same way: a spillway or sheer descent drives carbon dioxide out of the water, and pH rises as it goes.

So pH is read on every visit and brought back down before it drifts high enough to cloud the water or leave deposits. Chlorine also does less work at the high end of the range, which matters in a city where heat and sun already burn through it. If you ran the hose for an hour between visits, tell your technician so the reading has context.

Hardness that refuses to sit still

Calcium is harder to predict. Houston Public Works logged total hardness on the Main System anywhere from 43.5 to 229 mg/L during 2025. Pool equipment makers commonly ask for calcium hardness of 200 to 400 ppm, so a pool filled and topped off near the soft end of that spread can sit below target for months, and low-calcium water tends to pull calcium out of plaster and grout over time. Near the hard end the risk flips toward white scale at the waterline and in salt cells.

Weekly visits answer that with data instead of guesses. Calcium hardness is tested on a regular schedule and compared against your own earlier readings, so a slow slide in either direction is caught early. If your address says Houston but your water bill comes from a municipal utility district, the city report does not describe your water at all, and the first few visits establish where yours actually sits.

Live oak season in Tanglewood and other shaded yards

Tanglewood has roughly 5,000 trees, and its boulevard is lined with live oaks planted by the Tanglewood Garden Club. Live oaks are not fully deciduous. They hold their leaves through winter and drop them just before new growth comes in each spring, which is also when their stringy catkins come down. For a few weeks, a pool under that kind of canopy takes a heavy debris load in a short window.

During that stretch the weekly visit shifts its weight. Surface debris comes off before anything else, since a leaf or catkin that sinks becomes a vacuuming job and a drain on chlorine. The pump basket gets checked for packed stems that choke flow, and filter pressure is compared with last week's number. When it has climbed well above the clean baseline, a filter cleaning goes on the calendar before the returns go weak. The rest of the year, the same yard may need little beyond the standard visit.

Original-era pools and rebuilt-lot pools need different eyes

Meyerland, Sharpstown, Westbury and Braes Heights were laid out between the late 1940s and the 1960s, and a pool that has survived from those years has usually been resurfaced or re-equipped along the way. The rebuilt lots of Tanglewood and Braes Heights can hold something else entirely: a recent pool with a variable-speed pump and an automation panel setting the schedule.

On a worn, rougher finish, brushing earns its keep, because algae anchors in texture well before it shows color. On an automated pad, the question is whether a run time programmed in a mild month still turns the water over enough in August. Either way, the notes left after each visit become a history of your pool, and a gradual change reads as a pattern you can see.

On the weekly sheet for a southwest Houston pool

• pH brought back down after heavy hose top-offs and long water-feature runs
• Calcium hardness compared against your own earlier readings, not a citywide figure
• Pump basket and filter gauge through the spring live oak drop
• Run times on automated pads as summer heat builds
