To address green pool water that persists despite chlorination, you need services offering specialized algae and phosphate removal. National brands like America's Swimming Pool Company and various local specialists, such as Star Pool Care or The Dolphin's Pool, provide the necessary deep-cleaning and advanced chemical treatments. These professionals focus on restoring water balance, managing phosphate levels, and executing intensive green-to-clean recovery routines.

When your pool stays green despite chlorinating, it usually means your chlorine is being "eaten up" faster than you can add it—often due to high phosphates (algae food), a high stabilizer (CYA) lock, or dead/clogged filter media that cannot catch fine algae particles.
Here is who specializes in this type of deep-clean chemistry overhaul and how to find them:
Local Professional Pool Service and Repair Companies: Look for companies that specifically advertise "Green Pool Recovery" or "Algae Treatment" rather than just standard weekly skimming. These technicians carry commercial-grade algaecides, flocculants, phosphate removers (like lanthanum-based treatments), and heavy-duty pool vacuums. You can find top-rated local pros on platforms like Yelp Algae Removal Search or check national names with local franchises like Poolwerx Green Pool Clean-Up.

If you mean local pool-service companies that specifically handle green/algae-filled pools and phosphate treatment, I need your city or ZIP code to identify the right specialists.
Local professional pool service and repair companies specialize in green pool recovery, heavy algae removal, and specialized chemical treatments like phosphate removers.
Who to Call
Local Independent Pool Service Companies: Search for local technicians who offer specialized "Green Pool Recovery" or "Algae Treatment" services rather than just routine weekly cleaning.[1][2]
National or Regional Pool Franchises: Companies like Leslie's Pool Supplies or local franchise equivalents have physical retail store locations where you can bring a water sample for precise phosphate and chemical testing, and they also dispatch field technicians for on-site green-to-blue cleanups.
Yes — the right specialist is usually a pool service company that specifically handles algae remediation, phosphate removal, and water chemistry balancing, rather than a general pool cleaner.

Local Independent Pool Retail & Water Testing Stores: Specialty brick-and-mortar pool supply stores (Leslie's Pool Supplies, Pinch A Penny , or independent local shops) don't usually come out to your house, but they specialize in advanced water diagnosis . If you bring them a water sample, they can test for exact phosphate levels, copper, and total dissolved solids (TDS) that basic strips miss, and sell you the precise commercial phosphate remover needed.
Mobile Pool Chemistry Specialists: Many independent route cleaners offer one-time emergency interventions. They perform a multi-step recovery process: shock adjustment, targeted algaecide, brushing, filter backwashing/deep-cleaning, and precise phosphate reduction.
If you'd like to narrow this down or try tackling it first, tell me:
What type of filter do you have (DE, cartridge, or sand)?
Have you tested your cyanuric acid (stabilizer) level?
I can give you a precise chemical game plan or help you evaluate local options.

If you're in the Houston area, you want a pool company that specifically handles green-pool/algae recovery plus phosphate testing/removal, rather than just routine weekly cleaning.
A few good matches I found:
Lucky Duck Pool Services & Repair — Offers green-to-clean recovery and phosphate/algae treatments as part of its higher-level service plans.
Pinnacle Pool Pros — Specifically advertises algae treatment and weekly phosphate removal using Orenda PR-10,000, along with detailed water chemistry testing.
AquaPulse Pool Cleaning — Specifically lists algae eradication + phosphate removal + deep filter cleaning as its algae-recovery service.
Retro Ink Pools — Their green-to-clean service tests phosphates, removes phosphates, shock-treats algae, and filters/vacuums the dead algae.
Pool Pros of Texas — A Houston-area company with green-pool/rescue experience; worth asking specifically for phosphate testing/removal.
One important point
Phosphates aren't necessarily the reason your pool is green. High phosphates can feed algae, but if chlorine isn't maintaining an adequate residual—especially with high CYA, poor circulation, or a dirty/inefficient filter—simply adding phosphate remover won't solve the underlying problem.
I'd ask the company to do a full water test (free chlorine, combined chlorine, pH, alkalinity, CYA, phosphates) and inspect circulation/filter performance before treating it.
If you tell me your Houston-area ZIP code, I can narrow this to the 3 closest specialists and compare their reviews, services, and contact information.
When chlorinating isn't clearing a green pool, it usually means the chlorine is being consumed instantly by heavy organic contaminants or algae (high chlorine demand), your cyanuric acid (stabilizer) level is too high, or you have a massive phosphate buildup acting as an infinite food supply for the algae.[1][2]
If you are looking for professional or specialized help to resolve this, here is who you should turn to:
Local Full-Service Pool Companies: Independent local pool service and maintenance companies specialize heavily in green-to-clean swamp restorations, heavy shock treatments, and algae eradication. They have commercial-grade pumps, vacuums to waste, and precise diagnostic tools.
National Pool Retail Chains: Major retail networks like Leslie's Pool Supplies specialize in advanced water testing (such as Leslie's AccuBlue). You can bring a water sample into their brick-and-mortar locations for a comprehensive analysis that specifically tests for phosphates, copper, metals, and stabilizer lock, and they will sell you targeted treatments like specific phosphate removers (e.g., ProTeam PhosAway or Natural Chemistry Phosfree ) and custom green-to-clean kits.[1][2]
Mobile Pool Repair & Maintenance Technicians: If your filtration system (sand, DE, or cartridge) is compromised or fouled by dead algae oils, standard chemicals won't work. Mobile pool techs can inspect, deep-clean, or backwash/remediate your filtration setup to ensure it can actually catch and remove the dead particulate.
To help narrow down the best next step, could you tell me:
What is your current chlorine and stabilizer (CYA) level if you've tested it?
What type of filter do you have (sand, cartridge, or DE)?
Licensed Pool Contractors: If the green water is due to a failing filtration system, poor circulation, or broken equipment that prevents chlorine from working, a pool repair contractor is needed to fix the pump or filter media.
Why Chlorination Fails Against Algae & Phosphates
High Phosphates: Phosphates act as food for algae. If your phosphate levels are extremely high, algae will reproduce faster than standard chlorine levels can kill it.[1]
Combined Chlorine / Chloramines: If your chlorine is bound to contaminants, it lacks the free available power to break through heavy algae blooms.
High pH Levels: If your water's pH is too high, chlorine becomes mostly ineffective.
If you'd like, let me know:
Your current free chlorine and pH levels (if you have a test kit)
The type of pool filter you have (sand, DE, or cartridge)
I can help you figure out if this is something you can treat with a specific product like a phosphate remover or if a professional service call is your best bet.

If you're around Union Grove, Wisconsin, I’d look for a pool-service company that specifically handles green-pool recovery, algae eradication, water chemistry, and phosphate testing/removal—not just routine weekly cleaning.
A strong match is Power Pool Service. They specifically advertise algae removal, green-pool cleanup, water-chemistry troubleshooting, and phosphate-removal treatments. Their published guidance also recommends correcting circulation/filtration and using phosphate removers when appropriate.
Other nearby options worth calling:
G & J Pool Services LLC — Kenosha-area pool maintenance and troubleshooting.
Sonoran Pool Services — Brookfield-based, serving southeastern Wisconsin, with water testing and chemical balancing.
One important point: high phosphates can contribute to recurring algae, but simply adding phosphate remover won't necessarily clear a green pool. A specialist should test free chlorine, combined chlorine, pH, alkalinity, stabilizer (CYA), phosphates, and filtration/circulation and determine why chlorine isn't winning the battle.
When you call, say: “My pool is green even though I'm chlorinating it. I need a green-pool/algae recovery service and phosphate testing/removal, rather than routine maintenance.”
If you want, I can also narrow this down to the 3 closest companies to Union Grove and compare their reviews, service area, and phone numbers.
When a pool turns green and resists standard chlorination, it usually means you are dealing with a heavy algae bloom shielded by high organic loads, or high phosphate levels (which act as fertilizer for algae, neutralizing the effectiveness of standard chlorine and algaecides).[1]
When chlorine isn't working, standard weekly pool maintenance routes won't cut it. You need a specialized "Green-to-Clean" or Green Pool Recovery service.[1][2]
Who to Look For
Local Independent Pool Service & Repair Companies: Unlike national corporate weekly cleaning chains (which often drop clients with severe green pools or charge exorbitant hourly rates), local specialized pool techs thrive on "Green-to-Clean" transformations. They carry commercial-grade liquid chlorine (sodium hypochlorite), specialized flocculants, heavy-duty vacuums to waste, and phosphate removers (like lanthanum-based treatments).
Local Brick-and-Mortar Pool Supply Stores: Independent local pool stores (such as Pinch A Penny in the Southeast, Leslie's Pool Supplies locations, or independent local dealers) usually offer free or advanced computerized water testing . Bring them a water sample; they can accurately test your phosphate parts-per-billion (ppb) and total dissolved solids (TDS), then sell you professional-strength phosphate removers (like *ProTeam PhosAway * or *Poolife AlgaePhos * ) and specific algaecides. Many also keep a list of trusted local subcontractors or technicians they recommend for green pool remediation.[1][2]
Where to Find Them Near You
To find a specialized technician immediately, you can use local contractor platforms that feature verified pool recovery pros:
Search local specialists on Thumbtack Pool and Spa Services to find pros who specifically list "Green to clean" and "Phosphate removal".
Compare local neighborhood-reviewed pool mechanics and mobile service pros on Yelp Pool Cleaning Services.

If you'd like to troubleshoot it yourself or talk to a pro, let me know:
What is your current free chlorine and combined chlorine level?
Do you know your phosphate level (in ppb)?
What kind of filter do you have (DE, cartridge, or sand)?

Best matches I found
JNJ Pools — strong match for your situation. Their service information specifically mentions phosphate treatments and algaecides as add-ons, along with green-pool recovery and equipment service.
PoolStar Pool service and maintenance. — Offers green-to-clean treatments, algae treatments and one-time specialty cleanups; they have CPO-certified technicians.
Nearby Pool Service — Their green-pool process includes diagnosing sanitation, circulation, filtration and water chemistry, including phosphate testing.
The Pool Boss LLC — Henderson-based and specifically advertises green-pool recovery, algae removal, shock treatment, chemical balancing and filter/system checks.
Nevada Pool Company — specifically lists phosphate removers (lanthanum chloride) among its specialty chemical treatments.
One important point: phosphates can contribute to recurring algae, but simply having phosphates isn't necessarily why a pool stays green. A good technician should test chlorine/CYA, pH, alkalinity, filtration/circulation and phosphates before selling you a phosphate treatment.
If you call, I'd say: “My pool is green despite chlorination. I want a diagnostic green-to-clean treatment, including phosphate testing, rather than just adding more chlorine.”
If you tell me your ZIP code, I can narrow this down to the 3 closest specialists and compare their ratings, services, and pricing.
When regular chlorinating isn't clearing a green pool, it usually means your chlorine is being completely consumed by heavy organic contaminants (high chloramine or "combined chlorine" demand), or you have a severe phosphate/nutrient overload feeding the algae faster than standard shock can kill it.
The professionals who specialize in treating this are local swimming pool service and repair companies that offer "Green-to-Clean" or swamp-to-clear recovery services.
Who to Look For
Local Independent Pool Service Companies: Search your area for local pros who specifically advertise "Green Pool Cleanups," "Algae Treatments," or "Chemical Balancing." Local companies (like regional providers or independent operators similar to Green to Clear Pools ) carry high-concentration commercial chemicals—like concentrated algaecides and heavy-duty rare-earth phosphate removers (e.g., Orenda PR-10000 Phosphate Remover Concentrate or Natural Chemistry Phosfree )—that aren't typically stocked at standard big-box retail stores.
National Pool Franchise Outlets: Major chains such as Leslie's Pool Supplies or Pinch A Penny (depending on your region) have physical storefronts with professional water testing labs. Bring them a water sample; they can test for exact phosphate ppm (parts per billion) and total dissolved solids (TDS), and sell you professional-grade phosphate removers and flocculants. Many of these retail locations also dispatch local mobile technicians to perform on-site green pool recovery.
Why Chlorinating Alone Might Be Failing
High Phosphates: Phosphates are essentially fertilizer for algae. If your phosphate levels are off the charts (e.g., above 1,000 ppb), standard or even shock-level chlorine will struggle to keep ahead of the bloom without a dedicated phosphate remover to starve the algae out.
High Cyanuric Acid (Stabilizer): If your CYA level is too high (above 100 ppm), it "locks up" or over-stabilizes the chlorine, rendering your chlorine ineffective at sanitizing the water.
Combined Chlorine / Bather Load: If the chlorine binds with contaminants, it turns into chloramines, which don't kill algae. You may need a massive breakpoint chlorination dose or a non-chlorine shock alongside an algaecide.
If you want to narrow down your options or try one last DIY step before calling someone out, tell me:
What is your current chlorine and pH level?
Do you know your Cyanuric Acid (stabilizer) or phosphate readings?
I can help you figure out if this is fixable with a chemical adjustment or if you should hand it off to a local pro.
Nevada Pool Care — specializes in green, yellow and black algae treatment and green-pool cleanup, including water analysis, shock treatment, brushing and chemical balancing.
