Summer Pool Care 101: Keeping Your Fiberglass Pool Clean in East Tennessee’s Heat

Summer in East Tennessee is beautiful—but when temperatures climb, your pool care routine needs to rise with it. If you own fiberglass pools in Knoxville TN, understanding how to maintain them during the hottest months is essential. While fiberglass pools are lower maintenance than other types, summer heat brings unique challenges, including algae growth, chemical imbalances, and fluctuating water levels.

At Foothills Outdoor Designs, we help Knoxville homeowners install and maintain beautiful, long-lasting fiberglass pools. Let’s walk through exactly how to keep your pool clean, clear, and swim-ready all season long.

Why Fiberglass Pools Are Easier to Maintain in the Heat

Not all pools are created equal when it comes to Tennessee summers. Fiberglass pools have a non-porous surface that naturally resists algae and debris buildup, making them ideal for low-maintenance care. Unlike concrete or vinyl liner pools, fiberglass doesn’t absorb heat as aggressively, which helps maintain more stable water temperatures and reduces chemical fluctuation.

If you own or are considering fiberglass pools in Knoxville TN, you’ll love how manageable they are—especially when following a consistent summer care schedule.

Weekly Maintenance Checklist for Knoxville Summers

Here’s what you should do every week to keep your pool in top shape during the summer heat:

• Test and balance your water
  Heat affects chlorine levels. Test chlorine, pH, alkalinity, and stabilizer levels weekly and adjust as needed.
• Skim, vacuum, and brush
  Even with fiberglass, debris and pollen can accumulate. Skim daily and vacuum weekly. Brush the waterline to prevent buildup.
• Shock the pool
  High heat and heavy use call for regular shocking—at least once every two weeks, or more after pool parties.
• Clean the filter
  Whether you have a cartridge, DE, or sand filter, clean it regularly to ensure good water circulation.
• Monitor water level
  Knoxville’s summer sun and frequent storms can drastically change your water level. Refill as needed to keep it mid-skimmer.

Beating Algae Before It Starts

Algae love hot, stagnant water. Luckily, fiberglass pools in Knoxville TN are more resistant thanks to their smooth, gel-coated surface—but they’re not completely immune.

To prevent algae:

• Run your pump for 8–12 hours a day
• Brush corners and steps where algae might cling
• Keep chlorine levels between 1–3 ppm
• Use algaecide preventatively once per week

If you spot green, cloudy, or slippery areas, act fast with a shock treatment and thorough cleaning.

Chemical Tips for Heat Waves

When Knoxville temps hit 90+ degrees, chlorine depletes faster. Here’s how to adapt:

• Use a stabilizer (cyanuric acid) to protect chlorine from UV breakdown
• Consider switching to liquid chlorine or saltwater systems for more consistency
• Keep pH between 7.4–7.6 to avoid scale buildup or corrosion
• Avoid adding chemicals during the hottest part of the day—wait until evening for better efficiency

Staying ahead of chemical shifts will keep your pool water sparkling and skin-friendly.

When to Call in a Pool Professional

Even the most dedicated pool owners occasionally need backup. Call in a professional like Foothills Outdoor Designs if:

• Your pool water turns green or cloudy and doesn’t clear after shocking
• You notice cracks or fading in your fiberglass shell
• Your filtration system isn’t circulating well
• Your chemical levels constantly fluctuate
