How Often Should You Service Your Pool in Colorado?

Colorado pool owners face a unique set of challenges that most pool care guides simply don't account for. At 5,280 feet above sea level in Denver — and even higher in the foothills — your pool chemistry, equipment wear, and seasonal timing all behave differently than they do at sea level.

Why Colorado Pools Need More Attention

Three factors make Colorado pool maintenance more demanding than the national average:

• High UV intensity: At altitude, UV radiation is significantly stronger, which degrades chlorine up to 30% faster than at sea level. Pools can go from balanced to algae-prone within days during summer.
• Low humidity: Colorado's dry air accelerates evaporation, concentrating minerals and throwing off your water's total dissolved solids (TDS) faster than in humid climates.
• Temperature swings: A 70°F afternoon followed by a 40°F night stresses pool equipment seals, gaskets, and plumbing — especially during spring and fall.

The Recommended Service Schedule for Colorado Pools

Weekly (During Swimming Season: May–September)

• Test and balance water chemistry (pH, chlorine, alkalinity, cyanuric acid)
• Skim the surface and brush walls and steps
• Vacuum the pool floor
• Empty skimmer and pump baskets
• Inspect equipment for leaks or unusual sounds

Due to Colorado's high UV, we recommend testing chlorine levels twice a week during peak summer months (July–August) when temperatures are highest and pool use is heaviest.

Monthly

• Backwash or clean the filter (sand, cartridge, or DE)
• Check and adjust stabilizer (cyanuric acid) levels
• Inspect pump motor, filter pressure gauge, and all fittings
• Test calcium hardness and total dissolved solids
• Shock the pool (especially after heavy use or a rainstorm)

Seasonally (Spring Opening & Fall Closing)

• Spring opening (April–May): Remove and clean cover, inspect all equipment after winter, balance water from scratch, check for freeze damage
• Fall closing (September–October): Lower water level, blow out lines, add winterizing chemicals, install cover — critical to prevent freeze damage to plumbing

Signs You're Not Servicing Your Pool Often Enough

• Green or cloudy water (algae growth from low chlorine)
• Burning or red eyes after swimming (pH imbalance)
• Visible scale buildup on tile or equipment (high calcium hardness)
• Pump running louder than usual or losing prime (equipment stress)
• Filter pressure consistently above normal range

DIY vs. Professional Service: What Makes Sense?

Many Denver pool owners handle weekly skimming and chemical testing themselves, which is perfectly reasonable. Where professional service pays for itself is in:

• Catching equipment problems early — a trained eye spots a failing pump seal or cracked filter housing before it becomes a $2,000 repair
• Seasonal openings and closings — improperly winterized pools are one of the most common (and expensive) mistakes Colorado pool owners make
• Water chemistry accuracy — professional-grade testing equipment is significantly more accurate than consumer test strips
