Green Water Doesn't Clear Itself

Algae spreads fast in Phoenix heat, and a pool that looks hopeless is usually recoverable. Know what the work involves before you hire anyone.

  • Slimy walls and cloudy water point to growth that keeps spreading
  • Failed DIY rounds just add chemical cost
  • Check the ROC licence before you sign

Common problems

Signs Your Pool Needs Professional Cleanup

Green water, hazy water, slimy walls, floating clumps. Each one points to algae taking hold, and in a Phoenix summer it moves quickly.

Green, cloudy or yellow-green water

Colour and texture tell you what you are dealing with. Yellow-green and mustard growth behaves differently from deep green, so read yellow-green algae in your pool for the types.

Water that is cloudy but not green often has another cause. See cloudy pool water causes.

When it is more than a quick shock

Call a pro when:

  • Repeated treatments have failed
  • You lack the time or access to keep brushing and testing
  • Growth is heavy, with walls you cannot see through

Waiting costs more. Heavier growth takes more chemicals, more filter cleaning and more visits, and it can lead to draining or equipment repair.

Try it yourself first. Follow how to clean a green pool.

Sound familiar? Your pool turned green in Mesa or Gilbert. You shocked it twice. The water stayed cloudy and now the walls feel slick.

What it costs

What Drives the Price of Green Pool Cleanup

Green pool recovery is a service for water, not a structural repair. It is separate from resurfacing or leak repair.

The figures below come from Phoenix-area pool companies' own websites, checked October 2026. Most are entry prices, not typical totals.

Service Listed price
Green-to-clean restoration Starting at $295
Green to Clean (several companies) $300
Pool recovery, standard residential pool $300-$600
Green pool correction Start at $400
Green pool cleanout $600 (entry price)
Drain and refill $175
Pool drain and startup with chemicals From $325.00
Equipment repair or larger problems Depends on the job

One Phoenix company's site says standard residential pool recovery typically runs $300 to $600.

What to expect

How a Green Pool Recovery Works, Step by Step

The sequence is consistent across Scottsdale, Chandler and Tempe. Severity changes how long each step takes.

Step by step

Green pool recovery in six steps

  1. Restore circulation

    The pump and filter have to run.

  2. Brush

    Scrub walls, steps and floor to loosen algae.

  3. Test and rebalance

    Measure and adjust the water chemistry.

  4. Shock

    A sanitiser dose kills the growth.

  5. Run and clean the filter

    Dead algae loads the filter fast.

  6. Retest

    Check chemistry again once the water clears.

  1. Restore circulation. The pump and filter have to run.
  2. Brush. Walls, steps and floor get scrubbed to loosen algae.
  3. Test and rebalance. Water chemistry is measured and adjusted.
  4. Shock. A sanitiser dose kills the growth.
  5. Run and clean the filter. Dead algae loads the filter fast.
  6. Retest. Chemistry is checked again once the water clears.

Clearing time depends on how bad the pool is. Be wary of any firm promise before someone has seen the water.

What a pro adds

A pro tests, treats and returns to check results. Ask whether follow-up visits and filter cleaning are in the quote.

A dirty filter is a common reason treatment stalls. See pool filter repair and replacement if yours is worn.

Choosing a company

How to Verify an Arizona ROC Licence

Arizona requires a licence for pool repair and home repair jobs above $1,000 or needing a building permit.[2] The R-6 class covers service and minor repair of residential pools, while B-5 covers construction and repair.[1]

Whether routine chemical service alone needs a licence, confirm on the ROC licence lookup.

Check before you hire

  • Search the contractor on the ROC Contractor Search
  • Confirm the licence is active and the class fits the job
  • Check bond and Recovery Fund status
  • Get a written contract with the licence number, price, payment terms and ROC complaint notice
  • Do not pay in cash

"Licensed, bonded and insured" in an ad proves nothing on its own. Read is it enough in Arizona and Arizona pool licence classes.

Questions Valley pool owners ask

Starting a basic pool cleaning company is fairly accessible and low-cost, but Arizona requirements become stricter once you move into repairs or construction. Routine cleaning and maintenance generally requires less licensing than repair work, but you should confirm current rules with the Arizona Registrar of Contractors (ROC).

  1. Choose your service scope - Decide whether you will offer only weekly cleaning or also repairs. Repairs typically require an ROC contractor license (CR-6 or R-6 for pools and spas).
  2. Register your business - Form an LLC or sole proprietorship, get an EIN, and obtain a city business license in your service area (Phoenix, Scottsdale, Mesa, etc.).
  3. Get insurance - Carry general liability insurance, and workers' compensation if you have employees.
  4. Obtain certifications - A Certified Pool Operator (CPO) credential from the National Swimming Pool Foundation is valued by customers and helps with chemical handling knowledge.
  5. Buy equipment and supplies - Budget for a service truck, vacuum, brushes, test kits, and chemicals ($3,000-$15,000 startup range depending on setup).
  6. Build routes - Start with a cluster of nearby pools to keep drive time low, then grow through referrals and online listings.
