The pool is open, the water looks good, and the weather is heating up—welcome to swim season. But before you sit back and relax with your favorite float, now is the perfect time to run a mid-spring maintenance check.

Why? Because after the initial excitement of opening your pool, it's easy to let a few key tasks slide. But skipping these steps now could lead to bigger problems later—like algae outbreaks, cloudy water, or unnecessary equipment wear.

Here are five simple but important maintenance must-dos to keep your pool running smoothly through the rest of spring and into summer.

You probably tested and balanced your pool water when you opened it—but early-season weather can throw things off quickly. Rain, heat, and added swimmers can change your chemical levels faster than you think.

• Test your water at least once a week
• Focus on pH, chlorine, alkalinity, and calcium hardness
• Adjust as needed with individual balancers or an all-in-one treatment
• Pro Tip: If you want to simplify your routine and keep things consistent, E-Z POOL® provides weekly oxidation, algae prevention, stain and scale control, and water balance—all in one step. It’s a great way to stabilize your chemistry before peak summer use.

Even if your water looks clear, brushing your pool walls helps remove fine debris, prevent algae buildup, and keep surfaces clean. Algae can begin forming in areas of poor circulation, like corners, ladders, and steps—even if you don’t see it yet.

Brush:

• Steps and ledges
• Under waterline tiles
• Behind ladders or handrails

A quick weekly brushing takes less than 10 minutes and can save you hours of cleanup later.

Your filter worked hard during opening—and it’s probably been catching a mix of pollen, fine debris, and oils ever since. If it’s overdue for a cleaning, you may start to notice hazier water or slower circulation.

Depending on your filter type:

• Sand/DE Filters: Backwash when the pressure gauge reads 8–10 psi above normal
• Cartridge Filters: Remove and rinse thoroughly; deep clean with a filter cleaner if needed
• Pro Tip: Using ENZymePRO® alongside a clean filter helps break down oils and organic matter before they clog things up, making filtration more efficient and extending the time between cleanings.

Phosphates are a common fuel source for algae, and they can build up from rain, runoff, leaves, or even fill water. High phosphate levels often go unnoticed—until an algae bloom appears.

Use a phosphate remover like Revive!® WEEKLY to keep levels in check. It also helps:

• Prevent scale buildup on tile and salt cells
• Clear out organic debris and fine particles
• Improve water clarity without additional clarifiers

It's an easy once-a-week treatment that acts like insurance against cloudy water and early-season algae blooms.

A small drip now can become a big repair later. Take a few minutes to inspect your:

• Pump and filter connections
• Valves and fittings
• Heater or salt system
• Skimmer and return jets

Look for:

• Unusual noises or vibrations
• Damp areas around plumbing
• Decreasing water levels (outside of evaporation)

Catching leaks or wear early can prevent damage to equipment and help maintain chemical stability.

If your pool is already being used—or will be soon—now’s the time to get into a weekly rhythm. The more consistent you are now, the fewer issues you’ll have to react to later.

• Stick to a once-a-week product like E-Z POOL®
• Use ENZymePRO® to control buildup and reduce chlorine stress
• Treat with Revive!® WEEKLY to manage phosphates and enhance clarity

Spring is when your pool lays the groundwork for a clean, low-maintenance summer. These mid-season must-dos are simple, fast, and effective—and they’ll help you avoid the headaches that come from waiting too long.

Whether you're already hosting pool days or just prepping for Memorial Day weekend, this checklist ensures your pool stays swim-ready for the season ahead.
