How Do I Close An Above Ground Pool

Okay, so picture this: me, floating on a ridiculously oversized inflatable swan, soaking up the last rays of summer sun. It was pure bliss… until I realized the leaves were starting to turn and that distinct autumnal chill was sneaking into the evening air. Cue dramatic music. My pool days were numbered. And that meant… closing the pool. Ugh.
Closing an above ground pool isn't exactly the highlight of anyone's year, let's be honest. It's right up there with cleaning the gutters or filing taxes. But hey, somebody's gotta do it! And doing it right is crucial to avoid a springtime nightmare of algae, frozen pipes, and a generally unhappy swimming situation. So, let's dive in (pun intended!) and figure out how to properly close your above ground pool.
First things first: Timing is everything!
You don't want to jump the gun and close too early, especially if you're still getting some use out of it. But equally, waiting too long and risking a freeze is a bad idea. Generally, when the water temperature consistently stays below 60°F (around 15°C) it's time to take action. Keep an eye on the forecast! Remember that random cold snap last year? Yeah, avoid that!

Cleaning, Cleaning, Cleaning!
Seriously, do not skip this step! Think of it as a spa day for your pool before its long winter nap. Give it a thorough vacuum, skim any debris, and brush the walls and floor. Trust me, a clean pool now means less work when you open it next spring. You’ll thank yourself later. Nobody wants to open their pool to a swamp thing. Unless you’re into that sort of thing… then by all means, skip the cleaning! Just kidding. Don't.
Water Chemistry: Get it Right!
This is where the science comes in. You need to get your water chemistry balanced before closing. This involves testing your water and adjusting the pH, alkalinity, and calcium hardness. Aim for: * pH: 7.2 - 7.6 * Alkalinity: 80 - 120 ppm * Calcium Hardness: 200 - 400 ppm

After balancing, shock your pool with a high dose of chlorine. This will kill any remaining algae and bacteria. Follow the instructions on your shock product carefully! Let the chlorine level drop back down to a safe level (around 1-3 ppm) before moving on to the next step. Don't go swimming in it right after shocking! That's a recipe for itchy skin and regret.
Lower the Water Level
This step is crucial to prevent damage from freezing. Lower the water level to about 4-6 inches below the skimmer. You can use a submersible pump or simply siphon the water out using a hose. Pro tip: Use the siphoning method to water your garden! Two birds, one stone.
Prepare the Plumbing
Now for the slightly annoying part. You need to disconnect all your plumbing: filter, pump, heater (if you have one). Drain all the water from these components and store them in a dry, sheltered location. Any water left inside can freeze and cause cracks. Nobody wants a cracked pump housing in the spring. Trust me, I've been there.

For the pool lines, use a shop vac to blow out any remaining water. You can also use pool antifreeze (the non-toxic kind!) to fill the lines and prevent freezing. Plug all the openings with expansion plugs. This is super important!
Covering Up
Invest in a good quality winter pool cover. A properly fitted cover will keep debris out of your pool and prevent sunlight from fueling algae growth. Secure the cover tightly with cable and winch. Make sure it's taut and won't sag in the middle. A saggy cover is just an invitation for leaves and rainwater to collect. And nobody wants that.

Adding Winterizing Chemicals
Even with all the cleaning and balancing, it's still a good idea to add winterizing chemicals to your pool. These chemicals will help prevent algae growth and scale buildup over the winter. Follow the instructions on the product carefully! Overdoing it won't make your pool magically cleaner, it’ll just waste money.
Final Check
Before you walk away for the winter, do a final check. Make sure everything is properly disconnected, drained, and covered. Check that the cover is secure and that there are no obvious signs of potential problems. A little extra vigilance now can save you a lot of headaches later.
Closing an above ground pool might seem like a daunting task, but it’s totally manageable. Break it down into smaller steps, take your time, and you’ll be enjoying crystal clear water again next summer. Now go forth and conquer! You got this! And hey, at least you can daydream about those sunny pool days while you're shoveling snow, right? Okay, maybe not. But at least you'll have a clean, healthy pool to look forward to.
