As winter fades and warmer days roll into Central Delaware, it’s time for pool owners to gear up for the swimming season. Whether you're a seasoned pool pro or a first-time homeowner, proper spring maintenance is essential for a clean, safe, and stress-free pool experience.Here’s your go-to spring pool maintenance checklist—along with a look at the chemicals and professional services that make the job easier.

1. Start with the Cover

Begin by clearing any debris or standing water from your pool cover. Once it’s dry, fold it up and store it in a cool, dry space to avoid mildew and extend its lifespan.Pro tip: Check your cover for rips or wear before storing. If it didn’t hold up over the winter, now’s the perfect time to replace it.

2. Clear Out Debris

Before turning on any equipment, scoop out leaves, branches, and other debris that may have settled into the pool. Use a leaf net or skimmer to get the surface, and if needed, vacuum the bottom.If your water level dropped over the winter—which is common—top it off to about halfway up the skimmer opening.

3. Inspect Your Equipment

Cold snaps in Delaware can take a toll on pool systems. Before running anything, give your equipment a once-over:

  • Look for cracks or leaks in your pump and filter
  • Check your heater (especially the pilot light if you have gas)
  • Inspect gaskets, valves, and lines for any signs of wear or dry rot

Once everything looks good, power it up and let the system circulate. Strange noises, poor flow, or air bubbles could be early warning signs of bigger issues.Not sure everything’s working right? Our pros at Family Pool Maintenance can perform a full system check and handle any repairs or tune-ups you need.

4. Brush and Vacuum the Pool

With your system up and running, it’s time to give your pool walls, steps, and floor a good scrub. Brushing loosens up dirt and algae that can cling to surfaces. After that, vacuum the pool thoroughly to remove anything that’s settled on the bottom.Don’t forget to backwash or clean your filter if it’s due—it makes a big difference in water clarity.

5. Balance the Water Chemistry

This step is key for a safe, sparkling pool. After months of sitting idle, your water chemistry is likely off-balance. Start by testing:

  • pH: 7.4 – 7.6
  • Chlorine: 1.0 – 3.0 ppm
  • Alkalinity: 80 – 120 ppm
  • Calcium Hardness: 200 – 400 ppm
  • Stabilizer (Cyanuric Acid): 30 – 50 ppm

Balancing early in the season prevents corrosion, cloudiness, and algae growth. And if the numbers seem overwhelming—don’t worry. Our team offers water testing and full balancing as part of our spring opening service.

6. Shock the Pool

Even if your water looks clear, it’s a good idea to shock your pool to eliminate any lingering bacteria, contaminants, or organic matter that built up over the winter. We recommend a chlorine-based shock in the evening, then letting the system run overnight to circulate it thoroughly.

7. Prevent Algae Before It Starts

Spring in Delaware often brings pollen, rain, and fluctuating temps—all of which can contribute to algae growth. Once the water consistently hits 60°F, those green invaders can move in fast.Adding an algaecide early helps protect your pool before issues start. We carry professional-grade algaecides designed for local water conditions to keep your water crystal-clear.

8. Schedule a Professional Opening
