Pool Algae Removal and Prevention in Allen and Collin County

Algae can turn a clear pool green in just a few days, especially during North Texas summers. Hamilton Pools removes the algae you have, restores your water quality and helps keep it from coming back.

Green Algae

The most common type. It floats in the water or coats surfaces.

Water looks green or cloudy
Walls and steps feel slippery
Most blooms clear within 24 to 48 hours with proper treatment

Black Algae

A stubborn type with root-like structures that cling to plaster.

Dark spots on walls, steps and floor
Resists normal brushing and chlorine
May need several days and multiple treatments

Mustard Algae

A yellow-green type that is common in North Texas.

Yellow or tan patches, often in shaded areas
Brushes off, then quickly returns if not fully treated
May need repeat treatments

Our Algae Treatment Process

Each type of algae needs a different approach. Here is how we clear it and confirm your water is safe again.

Test the waterWe take professional chemical readings so we know what caused the problem.
Brush every affected surfaceBrushing breaks up the algae colony so treatment can reach it. We also scrub the pool and empty the skimmer baskets.
Apply professional-grade algaecideWe choose the treatment that matches the type of algae in your pool.
Shock the waterA shock treatment kills what remains in the water.
Filter and vacuumWe run your filtration system continuously, vacuum out the dead algae and backwash the filter.
Rebalance and reportWe adjust all chemical levels, give you a report of the readings and tell you how long to wait before swimming.

Why Pools Turn Green

Algae grows when conditions favor it. The most common causes in our area are:

Chemical imbalance, especially low chlorine
Poor circulation from a weak pump or dirty filter
Warm water and strong sunlight in North Texas summers
Rain, wind-blown debris and other contaminants
Phosphates in the water, which act as food for algae

If your equipment is the problem, see our pool repair services or filter cleaning.

Please Do Not Swim in a Pool With Visible Algae

It reduces visibility, which is a safety concern
It can harbor bacteria
It may cause skin irritation
After treatment, wait until chlorine returns to normal (1 to 3 ppm)

How to Keep Algae From Coming Back

Prevention costs far less than a full green-pool recovery. These steps make the biggest difference:

Consistent weekly service with properly balanced chemicals
Phosphate treatments to remove algae's food source
Regular filter cleaning so water circulates well
Steady chlorine levels through the hottest months
Brushing walls and steps before algae can take hold

Good news for weekly customers: free algae treatments are included with our weekly pool maintenance plans. We check your pool at every visit and treat algae before it becomes visible.

Pool Algae Treatment FAQ

What types of algae do you treat?

We treat all types of pool algae including green algae (most common), black algae (stubborn, root-like structures), and mustard algae (yellow-green, common in North Texas). Each type requires a different treatment approach for complete elimination.

How do you treat algae in a pool?

Our algae treatment process includes: brushing all affected surfaces to break up the algae colony, applying professional-grade algaecide, shock treating the water, running the filtration system continuously, and vacuuming out dead algae. We also test and rebalance all chemical levels.

How long does it take to clear a green pool?

Most green algae blooms clear within 24–48 hours with proper treatment. Black algae and mustard algae may take several days and multiple treatments due to their resistant nature. We will keep working until your pool is crystal clear.

Is algae treatment included in weekly maintenance?

Yes. Free algae treatments are included as part of our weekly maintenance plans. We monitor your pool at every visit and treat algae before it becomes visible. Our phosphate treatments also help prevent future growth.

What causes algae to grow in pools?

Algae growth is caused by imbalanced chemicals (especially low chlorine), poor circulation, warm temperatures, sunlight, and the introduction of contaminants (rain, wind-blown debris, swimmers). North Texas heat and humidity create ideal conditions for rapid algae growth in summer.

Can I swim in a pool with algae?

We do not recommend swimming in a pool with visible algae. Algae reduces visibility (a safety concern), can harbor bacteria, and may cause skin irritation. After treatment, the pool is safe to swim in once chlorine levels return to normal (1–3 ppm).

How can I prevent algae from coming back?

The best prevention is consistent weekly maintenance with proper chemical balancing. We also recommend phosphate treatments to remove algae's food source, regular filter cleaning, and maintaining proper chlorine levels. Our technicians will advise you on the best prevention plan.

How much does a professional algae treatment cost?

Algae treatment is free for weekly maintenance clients. For one-time treatments, pricing depends on pool size and algae severity. Call (214) 402-8677 for a quote.
