Opening Your Pool After Wintertime

Why a Clean Opening Sets the Tone

How you open the pool in spring decides how the whole season goes. A careful start means balanced water, a happy filter, and clear blue water within days. A rushed start usually means green water, wasted chemicals, and a frustrating first few weeks. Slow and steady wins here.

Step 1: Clear and Store the Cover

Start by removing leaves, water, and grime from the cover before you pull it off—anything sitting on top will otherwise end up in the pool. Once it’s clean and dry, fold and store it properly so it lasts to the end of the season. This one habit prevents most opening-day messes.

Step 2: Refill and Reconnect

Top the water back up to its normal level, then reconnect and prime the pump, reinstall return fittings, and remove any winter plugs. Inspect seals, the filter, and visible plumbing for cracks while you’re there. Get circulation running before you touch the chemistry.

Step 3: Balance and Shock

Test the water and adjust pH and alkalinity first, then shock to clear out anything that built up over winter. Run the filter continuously for the first day or two and brush the walls and floor. Clarity that doesn’t arrive instantly is normal—give the system time to do its job.

When to Call a Pro

If the water stays green after a proper shock, equipment won’t prime, or you spot cracks and leaks, it’s worth bringing in help early. A professional opening catches winter damage before it becomes expensive and gets your season started on clear, stable water.
