Opening Your Pool for the Season in Santa Fe: A Checklist

After a Santa Fe winter, pool opening is one of the most satisfying jobs of the year — and one of the easiest to get wrong. Rushing it usually means weeks of fighting cloudy or green water. Here's the sequence that works.

When to open

Once daytime temperatures are consistently mild and the risk of a hard freeze has passed, it's time. There's a temptation to wait until you actually want to swim, but opening earlier is easier. Water that sits warming under a cover with no circulation is exactly how algae gets a head start. Open before the water warms up and you'll spend far less effort clearing it.

Step 1: Clean before you uncover

Remove debris, leaves, and standing water from the top of the cover before pulling it off. Dumping a winter's worth of muck into the pool at the last second creates work you don't need.

Step 2: Remove, clean and store the cover

Rinse it, let it dry fully, and store it dry — a damp cover put away for the summer comes out mildewed next fall.

Step 3: Reinstall equipment and plugs

Put back the drain plugs, pressure gauges, and any fittings you removed at closing. (This is where people discover the plugs they "definitely put somewhere safe" in October.) Reinstall ladders, rails, and accessories.

Step 4: Bring the water level up

Fill back to the middle of the skimmer. After a dry Santa Fe winter you may be adding a significant amount.

Step 5: Start the system and inspect closely

This is the most important step here. Start the pump and filter, then watch carefully for leaks. Our freeze cycles are hard on plumbing and equipment, and spring startup is when winter damage shows up — cracked fittings, a damaged pump housing, a split heater component. Better to find it now than in July.

Check that water returns properly to the pool and that the pump primes and holds pressure.

Step 6: Clean thoroughly

Skim, brush every surface (walls, steps, corners — algae hides in corners), and vacuum. Empty the baskets. Clean or backwash the filter.

Step 7: Test and balance the water

Test everything: alkalinity first, then pH, then sanitizer, then calcium hardness and stabilizer. After a winter of sitting plus fresh fill water, expect the numbers to be off. Balance in that order — adjusting pH before alkalinity is the classic way to end up chasing your tail.

Step 8: Shock and circulate

Shock the pool and run the filter continuously — often 24 hours or more — until the water clears. Cloudy is normal at this stage and usually resolves with filtration and time.

Step 9: Let it stabilize before swimming

Give sanitizer levels time to settle into a safe range before anyone gets in.

When to hand it off

If the pool is dark green, if the equipment doesn't start properly, or if you suspect freeze damage, a professional opening is worth it. Freeze-damaged plumbing in particular is something you want diagnosed correctly rather than discovered mid-season.
