Green-to-clean cost at a glance
What you'll pay depends almost entirely on how far gone the water is. A pool that's gone slightly green over a long weekend is a quick chemical recovery; a black, swampy pool that's sat for a month is a multi-day job that may need a drain. These are realistic 2026 ranges for the Encino area:
| Severity | What you're looking at | Typical price |
|---|---|---|
| Light green | Slight tint, water still clear-ish | $250 – $350 |
| Deep green / cloudy | Can't see the bottom; heavy algae | $350 – $500 |
| Black / swamp | Opaque, organic, possibly with debris | $500 – $900+ |
| Drain & acid wash | Beyond chemical recovery | $700 – $1,400+ |
Rule of thumb: if you can still see the bottom, it's usually a chemical recovery in the $250–$500 range. Once the water is opaque and you can't see the main drain, plan on the higher tiers — and possibly a drain-and-refill.
What drives the cost
Five things move the number:
- Severity. The single biggest factor — light tint versus a true swamp can be a 4x difference.
- Pool size. More gallons means more chemicals and more filter run time; larger Royal Oaks and Amestoy Estates estate pools cost more to clear.
- Filter condition. A clogged cartridge or DE filter has to be cleaned or replaced mid-recovery, or the water never clears.
- Whether a drain is needed. If algae is too far gone — or the hard LADWP water has stacked up cyanuric acid and TDS — a partial or full drain is cheaper than dumping chemicals at it.
- Valley summer heat. Encino's western Valley heat speeds algae regrowth, so a recovery started during a heat event needs aggressive sanitizer and tight follow-up to keep it from turning again.
Process & timeline
A typical Encino green-to-clean runs two to five days. We test and balance, then shock with a heavy chlorine dose; the pump and filter run continuously to pull dead algae out of suspension; we brush and vacuum to waste; and we clean or backwash the filter as it loads up — sometimes more than once. The water usually shifts from green to cloudy white to clear over the days as the algae dies and filters out. Severe or drained pools take longer, especially if an acid wash on the plaster is part of the job.
Preventing the next one
Almost every green pool in Encino traces back to a lapse — a skipped stretch of service, a failed pump, or a vacation with no coverage during a heat event. Consistent weekly service at $160–$260/month is far cheaper than recovering a pool once or twice a season. Keeping free chlorine in range, phosphates down, and the pump running enough hours in summer is what keeps a clear pool clear.
The bottom line for Encino
Budget $250–$500 for a typical green-to-clean, more if the pool is a true swamp or needs draining. The fastest way to know your number is a quick look — in person or from a couple of photos — for a firm, written quote before any work starts.
Encino Pool Service FAQs
Why is my Encino pool green?
Almost always low free chlorine that let algae take hold — often after a skipped service, a pump or filter failure, or a vacation with no coverage. Encino's western Valley heat speeds it up: phosphates from chaparral and canopy leaf litter feed algae, and a pool can go from clear to green in a few hot days once sanitizer bottoms out.
Can a green pool be cleaned without draining it?
Usually, yes. Most green pools recover chemically — shock, filter, brush, and vacuum over a few days. We only recommend a drain when the algae is too severe to clear economically, or when the hard LADWP water has built up so much cyanuric acid or TDS that no amount of chlorine will hold. We'll tell you which camp you're in before starting.
How long does a green-to-clean take in Encino?
Typically two to five days. Light green can clear in a day or two; a deep-green or cloudy pool needs continuous filtration and repeated filter cleaning, which takes longer. Black or swamp pools take the longest, especially if a drain and acid wash are involved. Summer heat can speed regrowth, so we keep sanitizer aggressive until the water holds.
Is it cheaper to drain and refill than to do a green-to-clean?
Sometimes. If the water is a true swamp or the LADWP fill water has stacked up cyanuric acid and TDS to where chemicals can't win, a drain-and-refill ($700–$1,400+ with an acid wash) can actually be the cheaper, faster path. For most green pools, though, a chemical recovery in the $250–$500 range is less expensive.
How do I stop my pool from turning green again?
Consistent weekly service is the real fix. Keeping free chlorine in range, phosphates controlled, and the pump running 8–10 hours in summer keeps algae from getting a foothold. Most repeat green pools in Encino are ones that paused service or ran the pump too few hours to save on electricity during the hottest weeks.
