We’re here to walk you through essential pool maintenance practices, from balancing water chemistry to cleaning best practices, ensuring your pool remains in top condition for years to come.
Your Gunite Pool’s Needs
Gunite pools are popular due to their durability, customizable designs, and elegant appearance. Deciding on the right dimensions and configuration from the beginning makes long-term care much easier, and our guide on how big your pool should be can help you consider important factors like size, shape, and layout before you build. Like any pool, they require specific maintenance to prevent surface wear, staining, and water imbalances.
Are Gunite Pools Hard to Maintain?
Gunite pools require regular upkeep, but with the right approach, they are no more difficult to maintain than other pools. The key is consistency: staying on top of water chemistry, cleaning, and equipment care will prevent costly issues down the road.
What Is the Lifespan of a Gunite Pool?
A well-maintained gunite pool can last 50 years or more, though the interior surface should be resurfaced approximately every 10 years. Keeping the water properly balanced and addressing minor repairs promptly will extend the life of your pool.
The Essentials of Gunite Pool Maintenance
Focus on four key areas to keep your gunite pool in optimal condition.
Water Chemistry
Ensuring balanced water prevents algae, staining, and surface degradation.
Cleaning & Debris Removal
Regular skimming, brushing, and vacuuming keep your pool clear and prevent buildup.
Equipment Maintenance
Pool pumps, filters, and skimmers must be cleaned and maintained for proper function.
Seasonal Adjustments
Pool care changes with the seasons, requiring different
Your PhD in pH: Pool Water Chemistry
Balanced water chemistry is the foundation of proper pool maintenance. Poorly maintained water can damage your pool’s surface, encourage algae growth, and cause swimmers discomfort.
What Does pH Do for a Pool?
The pH level determines how acidic or basic your pool water is. A pH that is too high or too low can cause skin and eye irritation, damage pool equipment, and reduce the effectiveness of chlorine.
Pool Chemicals and Their Ideal Levels
To keep your pool water safe and balanced, test it regularly and adjust the following chemical levels as needed:
pH
7.2 – 7.8 (prevents irritation and protects surfaces)
Chlorine
1 – 3 ppm (keeps water sanitized and free of bacteria)
Alkalinity
80 – 120 ppm (helps stabilize pH levels)
Calcium Hardness
200 – 400 ppm (prevents calcium buildup in pools and plaster erosion)
How to Maintain Pool Chemicals
Test the Water Frequently
Use a reliable pool testing kit at least twice weekly.
Adjust Chemicals Gradually
If levels are off, add chemicals in small amounts, allowing time for circulation before retesting.
Shock the Pool When Necessary
After heavy use, rainstorms, or algae growth, shocking the pool with a high dose of chlorine helps restore balance.
Use Stabilizers as Needed
Sunlight can break down chlorine quickly—cyanuric acid (CYA) helps protect chlorine levels.
Monitor for Signs of Imbalance
Cloudy water, scaling, staining, or algae growth can indicate chemical imbalances that need immediate attention.
Cleaning Your Gunite Pool: Daily, Weekly, and Seasonal Tasks
Wondering how to clean a gunite pool? We’ve got you. Keeping your gunite pool clean helps prevent algae growth, extends the life of your pool surface, and reduces strain on your filtration system.
How to Keep a Pool Clean: Daily and Weekly Maintenance
Consistent cleaning prevents debris buildup and maintains water clarity. Follow these simple routines:
Daily Pool Tasks
Skim the Surface
Use a long-handled skimmer to remove leaves, bugs, and floating debris before they sink and cause stains.
Check Water Levels
Ensure the water stays at the midpoint of the skimmer opening for proper circulation.
Monitor Water Clarity
Cloudy water may indicate an issue with filtration or chemical balance.
Weekly Pool Tasks
Brush the Pool Walls and Steps
Gunite surfaces are porous, making them prone to algae and stains. Brushing once a week helps prevent buildup.
Vacuum the Pool
Whether using a manual or automatic pool vacuum, weekly vacuuming removes dirt and sediment from the pool floor.
Empty Skimmer and Pump Baskets
Keeping these debris-free allows for proper water circulation.
Check and Adjust Chemicals
Even if you tested earlier in the week, give your water a second look, especially after heavy rain, high usage, or extreme temperatures.
Seasonal Cleaning Tasks for Pools
Inspect the Pool Surface
Look for cracks, rough patches, or calcium buildup that may require resurfacing.
Deep Clean the Filter
Depending on the type (sand, cartridge, or DE), clean or replace the filter as needed.
Adjust Maintenance Based on the Season
Increase skimming and vacuuming in the fall due to falling leaves; shock the pool more frequently in the summer due to higher usage.
Best Automatic Pool Vacuums
Investing in an automatic pool vacuum can make maintenance much easier if you want to reduce manual labor.
Robotic Cleaners
Ideal for deep cleaning, they scrub walls, floors, and steps while filtering debris.
Suction-Side Cleaners
Connect to your pool’s skimmer and vacuum debris directly into the filtration system.
Pressure-Side Cleaners
Use water pressure from the return line to propel themselves and collect debris in a separate bag.
Filter System Care
The pool filter removes dirt, oils, and fine debris from the water. Proper care depends on the type of filter.
Sand Filters
Backwash every 4–6 weeks and replace sand every 5 years.
Cartridge Filters
Clean cartridges with a hose every 2–3 weeks and replace annually.
DE (Diatomaceous Earth) Filters
Backwash when pressure increases by 10 psi and replace DE powder as needed.
Monitoring Water Flow & Circulation
Jets
Check that all return jets are properly directing water to promote even circulation.
Pump
Ensure the pump is running for at least 8–12 hours per day to keep water moving and prevent stagnation.
Flow
If you notice weak water flow, check for clogged baskets, dirty filters, or air leaks in the system.
Seasonal Pool Maintenance Guide
Each season brings unique challenges for pool maintenance. Adjusting your care routine accordingly will keep your pool in peak condition while reducing the risk of costly repairs.
Opening a Pool After Winter
When warmer temperatures return, it’s time to get your pool ready for swimming season. Here’s how to properly open a pool after winter.
Remove and Clean the Pool Cover
If you use a cover, clean and dry it before storing it to prevent mold and mildew.
Inspect Equipment & Plumbing
Check for leaks, cracks, or any damage caused by freezing temperatures. Ensure all components are functioning properly.
Refill Water Levels
Add water if necessary to bring it back to the midpoint of the skimmer opening.
Test and Balance Water Chemistry
Start by testing pH, alkalinity, and chlorine levels. Add chemicals as needed.
Shock the Pool
A high dose of chlorine eliminates bacteria and algae that may have developed during the winter months.
Run the Filtration System
Allow the pump and filter to run continuously for at least 24 hours to clear out any contaminants.
Brush and Vacuum the Pool
Remove any dirt or debris that may have settled at the bottom.
How to Close a Pool for Winter
Proper winterization prevents damage to your pool and equipment during freezing temperatures. Follow these steps to close a pool for winter.
Deep Clean the Pool
Skim, brush, and vacuum the pool thoroughly.
Lower Water Levels
Reduce the water level below the skimmer to prevent freezing damage.
Balance Water Chemistry
Add winterizing chemicals to prevent algae growth and scaling.
Drain & Store Equipment
Remove ladders, handrails, and any accessories. Store them in a dry place.
Winterize Plumbing
Blow out the plumbing lines to remove excess water and prevent pipe damage.
Cover the Pool
Use a secure pool cover to keep out debris and prevent evaporation.
Gunite Pool Resurfacing & Long-Term Care
Even with proper maintenance, your gunite pool will eventually need resurfacing to maintain its integrity and appearance.
How Often Do Gunite Pools Need to Be Resurfaced?
Gunite pools generally need resurfacing every 10 years, depending on the following factors.
Water chemistry consistency
(unbalanced water can degrade surfaces faster).
Frequency of use and exposure to environmental elements.
The type of finish
(plaster may need resurfacing sooner than pebble or quartz finishes).
Signs That Your Pool Needs Resurfacing
Look for the following signs that indicate your gunite pool may need resurfacing.
