Every Season Is a Fresh Start.
We'll Help You Get It Right.

From spring opening to winter closing, Tennessee Pool Supply is your guide through every phase of the pool season, with the supplies, expertise, and honest advice to keep your water clean, your equipment running, and your backyard ready.

Spring pool Opening

When Should You Start?

Earlier than you think. Begin your spring preparations before the water temperature climbs above 60°F; that’s when algae growth accelerates. Pool owners who wait until they can already see a problem are always playing catch-up.

What to Inspect Before You Open

  • Check the cover for damage and debris accumulation
  • Inspect all equipment — pump, filter, heater, and chlorinator — for wear or freeze damage
  • Check fittings, plugs, and valves for cracks or leaks
  • Inspect the pool surfaces for staining, scaling, or liner damage
  • Test the water before adding any chemicals

The Biggest Spring Opening Mistakes

  • Adding chemicals before testing; you don't know what the water needs yet
  • Over-shocking without addressing the root chemistry imbalance first
  • Skipping the equipment inspection and discovering a problem mid-season
  • Not adjusting pH and alkalinity before adding sanitizer, rendering it largely ineffective
Most importantly: confidence. You’ll know exactly what your pool needs, and you’ll see results.
Bring us a water sample early in the season, and we’ll build you a complete opening treatment plan based on your actual water chemistry.

Summer Maintenance

The Most Common Mid-Season Problems

Most summer pool problems trace back to one of three things: chemistry that drifted while no one was checking, heat that accelerated algae growth, or equipment running outside its optimal parameters. The fix is consistent monitoring.

How Often Should You Test?

At minimum, test your water weekly during active swim season; more frequently during heat waves, heavy rain, or after a large pool party. Water chemistry can shift meaningfully in 48 hours under the right conditions.

Weather Factors That Impact Chemistry

  • Heavy rain — dilutes chemicals and drops pH
  • Intense sun — burns off unstabilized chlorine rapidly
  • High temperatures — accelerate algae growth and chlorine consumption
  • Large bather loads — introduce contaminants that consume sanitizer
Bring us a sample anytime you notice changes in the water — in color, clarity, smell, or feel. We’ll tell you exactly what shifted and how to correct it quickly.

Fall Closing

Mistakes That Create Expensive Spring Surprises

  • Closing with unbalanced water - scale and staining develop over winter
  • Not winterizing equipment properly — freeze damage is costly and avoidable
  • Leaving the water level too high beneath a cover
  • Skipping the algaecide step — spring green water is often a fall closing failure
  • Closing too early while water is still warm — algae thrives under winter covers in warm water

Mistakes That Create Expensive Spring SurprisesWhat Every Homeowner Should Do Before Winter

  • Test and balance the water chemistry completely
  • Shock the pool
  • Add a quality winterizing algaecide
  • Lower the water level appropriately for your cover type
  • Blow out and plug all lines
  • Add winter plugs and remove equipment that shouldn't freeze
  • Secure and inspect the cover
