Green-to-clean cost at a glance
The price depends almost entirely on how far the water has gone. A pool that's slightly green after a hot canyon weekend is a quick chemical recovery; a black, swampy pool that sat all summer is a multi-day job that may need a drain. These are realistic 2026 ranges for the Studio City 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, often full of canyon 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 the main drain disappears, plan on the higher tiers — and possibly a drain-and-refill.
What drives the cost
Five things move the number:
- Severity. The biggest factor by far — a slight tint versus a true swamp can be a 4x difference.
- Pool size. More gallons means more chemicals and more filter run time; larger pebble-finish builds with water features cost more to clear.
- Filter condition. A clogged cartridge or DE filter must be cleaned or replaced mid-recovery or the water never clears — common in Studio City where canyon leaf debris loads the filter fast.
- Whether a drain is needed. If algae is too far gone, or hard LADWP water has stacked up cyanuric acid and TDS, a partial or full drain can be cheaper than chemicals.
- Valley summer heat. Studio City's hot, dry summers speed 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 Studio City 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 — often more than once where canyon debris is in the water. The pool generally moves from green to cloudy white to clear as the algae dies and filters out. Swamp or drained pools take longer, especially if the plaster needs an acid wash.
Preventing the next one
Nearly every green pool in Studio City traces to a lapse — a skipped service stretch, a failed pump, or a vacation with no coverage during a heat event. Consistent weekly service at $160–$260/month is far cheaper than one or two recoveries a season. Keeping free chlorine in range, phosphates down (the canyon leaf litter drives them up), and the pump running enough hours in summer is what keeps a clear pool clear.
The bottom line for Studio City
Budget $250–$500 for a typical green-to-clean, more if the pool is a true swamp or needs draining. The fastest way to get your number is a quick look — in person or from a couple of photos — for a firm, written quote before any work begins.
Studio City Pool Service FAQs
Why is my Studio City pool green?
Almost always low free chlorine that let algae take hold — usually after a skipped service, a pump or filter failure, or a vacation with no coverage. The canyon location makes it worse: decomposing eucalyptus, pine, and sycamore debris drives phosphates that feed algae, and Valley heat lets a clear pool turn 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 cyanuric acid or TDS to the point chlorine can't hold. We'll tell you which applies before starting.
How long does a green-to-clean take in Studio City?
Typically two to five days. Light green can clear in a day or two; deep-green or cloudy water needs continuous filtration and repeated filter cleaning, which takes longer — especially when canyon debris is loading the filter. Black or swamp pools take longest, particularly with a drain and acid wash. The hot, dry summers can speed regrowth, so we keep sanitizer aggressive until the water holds.
Does all the canyon debris make a green-to-clean cost more?
It can. Heavy eucalyptus, pine, and sycamore debris loads the filter and adds organic matter that consumes chlorine and feeds algae, so a debris-fouled pool often needs more filter cleaning and more vacuuming to waste. Canyon-lot pools that sat unserviced through a debris-heavy fall tend to land at the higher end of the range.
How do I keep my pool from turning green again?
Consistent weekly service is the real fix. Keeping free chlorine in range, staying ahead of the phosphate load from canyon leaf litter, and running the pump 8–10 hours in summer keeps algae from getting a foothold. Most repeat green pools in Studio City are ones that paused service or cut pump runtime during the hottest weeks.
