Pool Cleaning FAQ: 8 Questions Every Pool Owner Asks (Answered With Real Numbers)
What does professional pool cleaning cost?
Typical US pricing in 2026 looks like this:
- Weekly full service (chemicals included): $120–$260 per month, depending on region and pool size
- Chemical-only service: $80–$130 per month
- One-time cleaning: $150–$350
- Green-to-clean recovery: $400–$1,200+ depending on severity
Sunbelt markets (Florida, Texas, Arizona, Southern California) usually sit at the lower end because of competition; pools with attached spas, waterfalls, or screened enclosures trend higher.
What chemical levels should I be seeing on test strips?
Memorize (or bookmark) these targets:
- Free chlorine: 1–3 ppm
- pH: 7.4–7.6
- Total alkalinity: 80–120 ppm
- Cyanuric acid (stabilizer): 30–50 ppm
- Calcium hardness: 200–400 ppm
The one most owners get wrong is cyanuric acid. Every chlorine tablet adds stabilizer, and once CYA creeps past 100 ppm, your chlorine becomes dramatically less effective — the fix is a partial drain and refill, which is why pros rotate in liquid chlorine instead of relying on tablets year-round.
My pool turned green. Can I fix it myself?
Often, yes — if you catch it early. The standard recovery process:
- Brush all surfaces to break up algae film
- Balance pH down to 7.2 (shock works better in slightly acidic water)
- Shock at 3–5x the normal dose (roughly 3 lbs of cal-hypo per 10,000 gallons for a full bloom)
- Run the pump 24 hours a day until the water clears
- Clean or backwash the filter daily — it will clog fast
Expect 3–7 days. If the water is so green you can't see the first step, or it's turned black or swampy, that's usually a job for a pro with commercial-strength treatment and possibly a drain.
How long should I run my pump each day?
The rule of thumb is one full turnover of your water daily — for most residential pools, that's 8–10 hours in summer and 4–6 hours in winter. Variable-speed pumps let you run longer at low RPM, which filters better and can cut electricity costs by 50–70% compared to an old single-speed pump running the same schedule.
Why does my pool eat chlorine so fast?
The three usual suspects, in order of likelihood:
- Low stabilizer (under 30 ppm) — sunlight destroys unprotected chlorine in about 2 hours
- High bather load or debris — organic matter consumes chlorine on contact
- An invisible algae bloom starting in shaded corners, behind ladders, or in light niches
If you're adding chlorine daily and still reading near zero, do an overnight chlorine loss test: if you lose more than 1 ppm with no sun exposure, something in the water is consuming it, and it's time to shock.
Do I still need service in the off-season?
If your pool stays open (common in the Sunbelt), yes — but visits can often drop to biweekly, and monthly costs typically fall 20–30%. Cold water slows algae, but it doesn't stop pH drift, and a winter of neglect means an expensive spring startup. If you winterize and cover, one proper closing visit ($150–$300) protects your plumbing from freeze damage that can cost thousands.
The bottom line
You can absolutely handle basic skimming and testing yourself. But chemistry drift, equipment wear, and algae don't announce themselves until the damage is done — and a single green-pool recovery or cracked pipe can cost more than a year of professional service. If you'd rather spend your weekends swimming than scrubbing, a reputable local pool service will keep your water balanced, your equipment healthy, and your Saturdays free. Most offer a free first visit or water analysis — it costs nothing to see what your pool actually needs.
