You walked outside to find your Dallas backyard pool had turned completely green — and now you’re wondering if it’s salvageable. It is. Pool Cleaner Pro has recovered hundreds of green pools across the DFW area, and in most cases, we can have your water clear and swim-ready within 24 to 48 hours.
Why Dallas Pools Turn Green
Green pool water is caused by algae — specifically chlorophyte (green algae), which proliferates rapidly when pool chlorine levels drop below 1 ppm. In Dallas, this happens more frequently than in other climates for a few specific reasons:
Extreme heat accelerates chlorine burn-off. During a Dallas summer, UV rays can destroy unprotected chlorine in as little as two hours. If your cyanuric acid (stabilizer) is low and a heat wave hits, your chlorine can go from adequate to zero in a single afternoon.
Summer storms cause chemistry swings. Heavy rain dilutes your pool water, drops chlorine concentration, and introduces organic contaminants from runoff. The July–August storm season in North Texas is when we get the most green pool recovery calls.
Equipment failures leave pools unprotected. A pump that fails overnight during a hot week means stagnant water with no filtration — algae blooms quickly in standing warm water. If you suspect equipment failure, also see our pool equipment repair service.
Our Green Pool Recovery Process
Pool Cleaner Pro uses a proven, systematic approach to green pool treatment — not just dumping in chlorine and hoping for the best:
- Assessment — We test your water chemistry fully: pH, chlorine, alkalinity, stabilizer, phosphates, and TDS. This tells us exactly what the pool needs.
- pH adjustment — Shock treatment is 80% less effective when pH is outside 7.2–7.6. We correct pH first, every time.
- Superchlorination (shock) — A calibrated heavy chlorine dose is applied based on pool volume and current chemistry. We don’t guess — we calculate.
- Algaecide application — A commercial-grade algaecide is added to attack algae at a cellular level, preventing regrowth after the shock cycle.
- Extended filtration — We set your filter to run continuously (24 hours) to process dead algae out of the water column.
- Brushing — Every surface is brushed aggressively to dislodge algae colonies and expose them to the sanitizer in the water.
- Follow-up visit — We return within 24–48 hours to vacuum dead algae from the floor, retest chemistry, and confirm the pool is clear and swim-safe.
What You Should NOT Do With a Green Pool
Before we arrive, avoid these common mistakes that can make green pool recovery harder and more expensive:
- ❌Do NOT let anyone swim in it — algae water can cause skin irritation and ear infections
- ❌Do NOT add chlorine tablets without adjusting pH first — it’s largely wasted
- ❌Do NOT backwash your filter repeatedly — it can push algae back into the pool
- ❌Do NOT empty the pool — most Dallas pools can be recovered chemically without draining
Service Areas for Green Pool Recovery

Green Pool FAQ
How long does it take to clear a green pool in Dallas?
Most green pools in the Dallas area clear within 24–48 hours of proper treatment. Severe cases — pools that have been green for weeks or months — may take 3–5 days and could require partial draining. We’ll give you an honest assessment when we arrive.
Will I need to drain my pool to treat the algae?
In most cases, no. Chemical treatment successfully recovers the vast majority of Dallas green pools without draining. We only recommend partial draining when TDS (total dissolved solids) is dangerously high or when algae damage is severe enough that chemical treatment alone won’t be effective.
How do I prevent my pool from going green again?
Prevention is simple: consistent weekly professional service. Most of our green pool recovery clients in Dallas go on to become weekly cleaning customers — and they rarely, if ever, have another green pool problem.
