If you’re wondering how to maintain your fiberglass pool, you’ll be happy to know it’s one of the easiest pool types to care for. Thanks to its smooth, nonporous surface, a fiberglass pool resists algae growth and requires fewer chemicals than concrete or vinyl pools.

Below are the basic maintenance tasks to keep your fiberglass pool clean, safe, and swim-ready all season long.

Step 1: Clean the Pool Weekly

Use cleaning tools specifically designed for fiberglass surfaces. A pool skimmer net is usually sufficient for daily debris removal. You can also use a manual or automatic pool vacuum for a deeper clean.

Tip: Avoid abrasive scrub brushes, which can damage the gel coat of a fiberglass pool.

Step 2: Test and Balance Water Chemistry

Check your water chemistry 2–3 times per week. Ideal ranges for fiberglass pools:

• Chlorine: 1–3 ppm

• pH: 7.2–7.6

• Total Alkalinity: 80–120 ppm

• Calcium Hardness: 200–400 ppm

• Cyanuric Acid (CYA): 30–50 ppm

Because fiberglass doesn’t react with water, chemical balance is easier to maintain than with other pool types.

Step 3: Run the Pool Filter Daily

Run your pool pump long enough to complete at least one full water turnover per day. The exact runtime depends on your pool’s volume and pump flow rate, but a general estimate is 6–8 hours daily.

Pro Tip: Use a programmable timer or smart system to automate filtration and reduce manual oversight.

Step 4: Maintain Proper Water Level

Keep your pool water level above the skimmer opening. This helps ensure proper debris removal and prevents stress on your pool structure due to groundwater pressure.

Why it matters: If the water level drops too low, your skimmer won’t work effectively—and your pool could become vulnerable to floating or structural damage.

Why Fiberglass Pools Are Easier to Maintain:

• One-piece shell = no liner to replace or resurface

• Nonporous surface = less algae

• Stable water chemistry = fewer adjustments

• Lower chemical costs over time
