What Is a Gunite Swimming Pool?

Understanding Gunite Pools

First things first, what exactly is a gunite swimming pool? Gunite pools are a type of in-ground pool constructed from a mixture of cement, sand, and water sprayed over a framework of rebar. This construction method is renowned for its durability and versatility, allowing for a variety of shapes and sizes. The key here is maintenance—keeping that durable structure in pristine condition requires regular care and attention.

Why Gunite Pools Need Special Care

The Unique Characteristics of Gunite Pools

Gunite pools are not your average above-ground pools. Their construction makes them robust, but it also means they can be more susceptible to certain issues like algae growth and surface cracks. Regular maintenance helps prevent these problems and ensures your pool remains a safe and inviting place for a dip.

Daily Maintenance Tasks

Skimming and Cleaning

One of the most crucial daily tasks is skimming the surface of your pool. Debris like leaves, bugs, and other unwanted items can quickly accumulate on the surface. Use a pool skimmer to remove these. This simple task keeps your pool clean and reduces the strain on your filtration system.

Checking Chemical Levels

Maintaining the proper chemical balance in your pool is vital. Test the water daily using a pool testing kit. You’ll need to keep an eye on the pH levels, chlorine, and alkalinity. Here’s a quick guide to ideal chemical levels:

  • pH: 7.4 to 7.6
  • Chlorine: 1.0 to 3.0 ppm
  • Alkalinity: 80 to 120 ppm

If these levels are off, adjust them accordingly using pool chemicals available at any pool supply store.

Weekly Maintenance Tasks

Brushing and Vacuuming

Gunite pools can develop algae and dirt build-up on the walls and floor. Brushing the surfaces weekly helps prevent algae growth and keeps the pool looking clean. Use a pool brush designed for gunite pools to avoid damaging the surface.

Vacuuming the pool is another essential weekly task. Automatic pool vacuums can make this job easier, but manual vacuuming ensures you get every nook and cranny.

Backwashing the Filter

Your pool’s filter plays a crucial role in keeping the water clean. Backwashing the filter weekly helps remove trapped debris and keeps the system running efficiently. Check the manufacturer’s instructions for your specific filter type.

Monthly Maintenance Tasks

Shocking the Pool

Shocking your pool involves adding a high dose of chlorine to kill off any lingering bacteria and algae. This process is essential for maintaining water quality. Typically, you should shock your pool once a month, but you might need to do it more frequently during periods of heavy use.

Inspecting the Pool and Equipment

Take the time each month to inspect your pool and its equipment thoroughly. Look for any signs of damage, wear and tear, or potential issues. This includes checking the pool pump, filter, and heater. Early detection of problems can save you time and money in the long run.

Seasonal Maintenance Tasks

Preparing for Winter

If you live in an area with cold winters, preparing your gunite pool for the off-season is crucial. Winterizing your pool involves:

  1. Cleaning the pool thoroughly.
  2. Balancing the water chemistry.
  3. Lowering the water level.
  4. Draining and storing pool equipment.
  5. Covering the pool securely.

Opening for Summer

When the weather warms up, it’s time to get your pool ready for swimming season. This involves:

  1. Removing and storing the pool cover.
  2. Refilling the pool and balancing the water chemistry.
  3. Inspecting and reinstalling equipment.
  4. Cleaning and vacuuming the pool.

Dealing with Common Gunite Pool Issues

Algae Growth

Algae can be a persistent problem in gunite pools. Regular brushing and maintaining proper chemical levels help prevent algae growth. If you do notice algae, shock the pool and use an algaecide.

Surface Cracks

Gunite pools can develop surface cracks over time. Small cracks can be repaired using a pool patch kit. For larger cracks, it’s best to consult a professional.


Stains can occur due to metals, leaves, or other organic materials. Regular cleaning and using a metal sequestrant can help prevent stains. For existing stains, there are specific pool stain removers available.


How often should I test my pool’s chemical levels?

You should test your pool’s chemical levels daily to ensure a safe and balanced swimming environment.

What is the ideal pH level for a gunite pool?

The ideal pH level for a gunite pool is between 7.4 and 7.6.

How often should I shock my pool?

Typically, you should shock your pool once a month, but it may be necessary more frequently during periods of heavy use.

Can I use a regular brush for cleaning my gunite pool?

It’s best to use a brush specifically designed for gunite pools to avoid damaging the surface.

What should I do if I notice a crack in my pool?

For small cracks, you can use a pool patch kit. For larger cracks, it’s advisable to consult a professional.


Maintaining a gunite swimming pool might seem like a lot of work, but with regular care and attention, it becomes second nature. From daily skimming and chemical checks to weekly brushing and vacuuming, these tasks keep your pool in pristine condition. Don’t forget to shock your pool monthly and inspect for any potential issues. Seasonal maintenance ensures your pool is ready for both winter and summer, allowing you to enjoy a clean and safe swimming environment year-round.

Remember, prevention is better than cure. By staying on top of your pool maintenance, you can prevent common issues like algae growth, surface cracks, and staining. Now, armed with this comprehensive guide, you’re all set to keep your gunite swimming pool in tip-top shape. Happy swimming!
