Green pool cleaning services exist for one job: taking a backyard pool that has turned into a pond and getting it back to clear, balanced water you can swim in again. In Yuma that job often starts in the fall, when people come home after months away and open the back gate to a cloudy, green surprise.
This page explains what a professional green pool cleanup usually involves, why it takes several visits, what published cost guides say, when draining enters the picture, and what to set up before you leave for the summer. If the water only turned this week and you want to know what is going on and what you can safely check yourself, the guide My pool is green: how do I fix it? covers that.
Yuma Pool Cleaning Pro is a free phone number, (928) 615-5224, not a pool company. An automated assistant answers, you describe the pool in a sentence or two, and your call is handed to a locally owned pool business in the Yuma area that is independent of the line. That business visits, quotes in its own name and carries out whatever you agree to.
Three levels of green, and what each means for a cleanup
Pool companies tend to sort a green pool by how far it has gone. These are general descriptions, not official categories, but they help you explain the pool on the phone and understand the quote you get.
Light green or teal
You can still see the floor and the steps. Algae has started but has not taken over. This stage often clears with a careful chemistry correction, steady filtering and brushing over a short period.
Dark green
The water looks like pea soup and the deep end has disappeared. The algae load is heavy, the filter will clog quickly, and the job usually needs several return visits before the water turns blue again.
Black or swamp
Leaves, dust and dead algae have settled into sludge, and you may see mosquito larvae or smell rot. Expect the most labor here, and sometimes a conversation about whether the water is worth saving at all.
Why you should not wait on a dark pool
Murky water hides the floor. CDC tells swimmers to check that the main drain in the deepest spot is visible before they get in, because clear water is how people notice someone struggling below the surface. A green pool fails that test. CDC also says drowning kills more children ages 1 to 4 than any other cause, and most of those drownings happen in home pools.
Until the water is clear, keep the gate latched, keep children and pets away, and do not let anyone swim. If your pool has no fence or cover, that matters even more while it is green.
What a professional green pool cleanup involves
Every company has its own method, but most cleanups follow the same broad order. Knowing it helps you compare quotes and ask good questions.
- A first look. The technician checks the equipment, tests the water and judges how much debris is on the floor. Some green pools are green because the pump stopped or the timer failed, and that has to be fixed first or the cleanup will not hold.
- Removing the debris. Leaves, palm fronds and sludge come out with nets and a vacuum. Leaving them in feeds the algae and wastes chemicals.
- Filter work. Dead algae is fine material that packs filter media quickly. Plan on the filter being cleaned more than once during the job, and possibly a recommendation to replace worn cartridges or media.
- Treatment over several visits. The company corrects the chemistry, runs the system and brushes walls and floor, then returns to retest, brush and clean the filter again. The number of visits depends on how dark the water started.
- Handing it back. Once the water is clear and balanced, the company should tell you the readings and what routine will keep it that way, whether that is ongoing weekly pool service or your own care.
This page gives no chemical amounts on purpose. Treating a heavily green pool means handling strong oxidizers, and mixing the wrong products can release toxic gas. Leave the chemistry to the professional you hire.
The classic Yuma case: a pool left for the summer
Yuma County says its population grows by about 90,000 in winter, when sun-seeking seasonal residents arrive. Some of them own homes with pools, and those pools can sit with nobody watching them through the hottest part of the year.
That is exactly when water turns. National Weather Service normals for Yuma show about 118 days a year reaching 100 degrees or more, and Visit Yuma reports the city gets about 91 percent of its possible daylight hours. Strong sun breaks down chlorine, and warm water helps algae grow. A pump that trips off in June can leave a green pool by July.
What to arrange before you leave
- Line up routine service for the months you are gone, and agree on who the company calls if it finds a problem.
- Ask a neighbor or friend to look over the wall now and then, and give them a number to call.
- Check that the pump timer or automation is set for summer run times and that the breaker is on.
- Make sure the gate latches and locks, so the pool stays closed to children while it is unattended.
- Ask whoever visits to watch the water level, because a summer of evaporation can drop it below the skimmer.
How long a green pool cleanup can take
HomeGuide's pool cleaning guide says a neglected pool with green water can take up to a week or more to clean. A pool with a light tint and working equipment can recover much faster. These are the main things that stretch a job out:
- How dark the water isA swamp has far more algae and sludge to remove than a pale tint.
- The filterA small, worn or clogged filter slows everything and may need repeated cleaning.
- Debris on the floorMonsoon dust and fallen leaves add hours of vacuuming.
- The water itselfIf tests show the water is badly out of balance, treatment can work poorly, and a company may talk with you about draining.
- Broken equipmentIf the pump or timer failed, that repair comes first. See pool pump repair.
Mosquitoes and West Nile virus
Standing green water is not just ugly. Yuma County Public Health calls green, unmaintained pools one of the major breeding sources for the mosquitoes that carry West Nile virus, and the county has reported positive mosquito samples and a locally acquired human case. County releases say the local West Nile season usually runs June to October.
If a pool near you has been green for weeks, you can report it through the Service Request feature on the Yuma County website or call Yuma County Vector Control at (928) 317-4584.
What published guides say a green pool cleanup costs
HomeGuide's 2026 pool maintenance cost guide puts the first cleaning of a green pool at $300 to $500, followed by $100 to $150 a month for upkeep. It notes that pool size, pool type and saltwater systems all affect the price. These are national figures from a published guide, not prices from this line, and no publisher lists a Yuma-specific number. Real quotes vary with how green the pool is, its size, the filter and whether any equipment needs repair.
When you compare quotes, ask each company the same things:
- Is the price for the whole cleanup or per visit, and how many visits does it expect?
- Are chemicals and filter cleaning included, or billed separately?
- If the pool is still cloudy after the final scheduled visit, what then?
- Does it recommend draining, and if so, why?
- What is its Arizona Registrar of Contractors license number?
Arizona licenses contractors through the Registrar of Contractors (ROC). Its R-6 license covers residential pool service and minor repairs, and the ROC does not spell out whether plain cleaning needs a license, so ask. Whatever number a company gives you, enter it in the ROC contractor search (new tab) to see if it is active. Checking a license is up to you; the phone line does not do it.

When the water has to go: draining rules
Draining is a last resort, but sometimes the company decides the water cannot be saved. The rules depend on where the pool is.
Inside the City of Yuma
Call City of Yuma Utilities at 928-373-4500 before you drain. City code lists pool drainage among discharges that need authorization from the Director of Utilities. The city's stormwater page says to stop adding chlorine 48 hours before, run the hose into the sewer cleanout on your own property (never a public manhole), drain slowly during low-use hours, and never let the water run into the street.
Unincorporated Yuma County
For areas such as the Foothills and Gadsden, the county's pool drainage guide says chlorine must be at or below 1 part per million before release, saltwater pools may drain only to the sanitary sewer, and pool water may not be permanently connected to a storm drain or wash. Ask the company to follow these rules.
