The Hill Country changes the math
In a mild climate, bi-weekly pool service is a reasonable money-saver. New Braunfels is not a mild climate. Three local forces decide your cadence:
- Intense UV: Our near-vertical summer sun burns chlorine off the water within hours. Without weekly chemical top-ups, sanitizer can run out days before the next visit — and algae moves in the moment it does.
- Oak and cedar pollen: Spring oak pollen and the famous Hill Country "cedar fever" season drop a steady film of organic debris into the water. It feeds algae and clouds the surface fast.
- Summer storms: A single afternoon thunderstorm can dump leaves, dust, and runoff into a pool, spike phosphates, and knock chemistry sideways overnight.
A pool that looks perfect on a Monday can be turning by the following weekend in July. That's the core reason cadence matters more here than in most of the country.
When bi-weekly is genuinely fine
We're not going to upsell you weekly service you don't need. Bi-weekly (every other week) can work well when:
- It's winter. From late November through February, cold water slows algae to a crawl and chlorine lasts much longer. Many New Braunfels pools coast comfortably on bi-weekly or even monthly service in the off-season.
- The pool sees little use. A second home, a rarely-swum pool, or a screened/covered pool collects less debris and fewer swimmer contaminants.
- You handle the in-between week. If you're comfortable adding chlorine and emptying baskets on the off week, bi-weekly professional service plus your own touch-ups can hold a pool together — though it asks more of you than most owners want in summer.
When weekly is non-negotiable
- Summer (April–October). This is the big one. In peak Hill Country heat, the gap between a balanced pool and a green one is often five to seven days. Weekly service keeps chlorine and stabilizer where they need to be before algae ever gets a foothold.
- Heavy-use pools. Frequent swimmers, sunscreen, and lots of bodies in the water consume chlorine quickly. Bi-weekly can't keep up.
- Vacation rentals and short-term rentals. Around Gruene, Canyon Lake, and the Guadalupe and Comal river corridors, rental pools are mission-critical — a green pool means refunds and bad reviews. These should always be on weekly service, often with priority scheduling.
- Big trees overhead. Mature oaks shading a backyard are beautiful and brutal on a pool — they shed constantly.
The cost trade-off — honestly
Bi-weekly service looks cheaper on paper, and in the right season it is. But the comparison people forget is the cost of recovery. Weekly Full Chemical service runs about $110/month in New Braunfels. A single green-pool recovery costs $325 for a light bloom and up to $625 for a severe one. If a bi-weekly summer schedule produces even one green pool a season, you've erased your savings and then some — plus you've lost swim days during the hottest weeks of the year.
Our honest framing: in winter, bi-weekly can save you real money with little risk. In summer, the "savings" of bi-weekly are mostly a bet against algae — and in the Hill Country, the house usually wins that bet.
The algae-risk reality
Algae doesn't need much. Once free chlorine hits zero in warm water, a visible bloom can appear in 24–48 hours. A weekly visit caps the maximum time your pool can sit unsanitized at seven days; bi-weekly doubles that exposure window to fourteen. In April-through-October Comal County conditions, fourteen days without a chemical top-up is simply too long for most uncovered pools. That's not a sales line — it's the chemistry of chlorine demand under Texas UV. It's also worth noting that algae is far easier to prevent than to remove: a steady weekly dose of sanitizer never lets a colony establish, while a bi-weekly schedule occasionally gives one just enough room to take hold between visits. Once that happens, brushing and shocking the pool back to clear costs far more time and chemical than the maintenance would have. In our experience across New Braunfels, the homeowners who fight recurring algae every summer are almost always the ones stretching their service interval during the hottest stretch of the year.
Our recommendation for New Braunfels
For most homeowners here, the sweet spot is weekly service spring through fall, and an optional step down to bi-weekly for the winter months. It matches your spending to actual risk: you pay for protection when the climate is genuinely working against you, and you save when it isn't.
