How Long Can a Pool Stay Closed? Duration & Safety Limits

Between the winter thaw and spring opening every year, I'm left wondering if my pool's been closed too long and the water is now unsafe. My facility requires extended closure periods for various operational reasons, and I want to establish clear protocols for both planned seasonal shutdowns and emergency closures.

Specifically, I'm looking for data on maximum safe closure timeframes before water chemistry becomes unmanageable and equipment integrity is compromised. What are the industry standards for winterized pools versus temporary emergency closures?…more

Can You Shock Pool Without Running Filter? Safe Method

Spent years shocking my old above-ground pool without running the filter and it worked perfectly, but now I'm questioning if it's actually safe for this new setup. I need to shock my pool but I'm wondering if I absolutely have to have the filter system running while I do it? The pool store mentioned something about circulation being important, but they weren't super clear about whether that meant the filter specifically or just water movement in general.

I'm trying to figure out if there's a safe way to shock the pool even if my filter isn't running - maybe by brushing or using the return jets? Any guidance would be really appreciated since I don't want to mess this up!…more

Do I Need to Winterize My Pool? Complete Regional Guide 2024

My 20,000 gallon inground pool looked fine yesterday, but walked out this morning and spotted ice crystals forming around the edges that definitely weren't there last night. I live in central Pennsylvania where we definitely get freezing temperatures, but I'm trying to figure out the right strategy.

I've been maintaining my pool chemistry pretty well - chlorine stays around 2-3 ppm, pH is balanced at 7.4, and alkalinity is good at 100 ppm. The pool has been crystal clear all season. But now that October is here and nighttime temps are starting to drop into the 40s, I'm wondering what level of winterization is actually necessary for my climate zone.

Do I need to drain the pool, blow out all the lines, and do the full winterization process? Or are there different approaches depending on how cold it gets in my area? I want to make sure I protect my equipment and plumbing from freeze damage, but I also don't want to do more work than necessary if my climate doesn't require it.…more

Do Vinyl Pools Need Calcium? Complete CH Guide 2024

Before our big pool party this Saturday, I'm getting completely contradictory advice about whether my vinyl pool even needs calcium added! I keep reading conflicting info online - some sources say vinyl pools don't need calcium at all, others say they do but at different levels than concrete pools. My test strips show I'm sitting around 100 ppm right now and I'm not sure if that's too low or if I even need to worry about it.

I've been dealing with some metal staining on my vinyl liner and wondering if low calcium could be making it worse by causing corrosion. But I'm also terrified of adding too much and ending up with scaling or that dreaded cloudy water that takes forever to clear up. What's the sweet spot for calcium hardness in vinyl pools, and is it really different from other pool types?…more

How to Backwash Pool Filter - Complete Step-by-Step Guide

Apparently my pool filter started shooting dirty water back into the pool during what I thought was a normal backwash cycle yesterday.

The pool store told me I need to backwash my filter regularly, but I'm honestly not sure what that means or how to do it properly.

I see there's a multiport valve on my filter system with different settings like BACKWASH, RINSE, and FILTER, but I don't want to mess anything up by doing it wrong. Can someone walk me through the exact steps? Like do I turn the pump off first, and how long am I supposed to run it in each mode?…more

How Long Do Inground Pool Liners Last? Complete Guide

Replaced my inground pool liner three years ago — before I start tearing into another replacement would this failing liner be covered under my home warranty? The pool store mentioned that I'll eventually need to replace the vinyl liner, but they didn't give me much detail about timing.

How long do these liners typically last before needing replacement? Is it something I should be budgeting for in the next few years, or is it more of a long-term expense? I want to make sure I'm taking proper care of it so it lasts as long as possible.…more

Does Pool Stabilizer Evaporate? CYA Levels Explained

Does Pool Stabilizer Evaporate? CYA Levels Explained

Woke up determined to finally understand pool chemistry, but now I'm standing in the pool store aisle staring at bottles of cyanuric acid and chlorine stabilizer with no clue which one I actually need. I know chlorine evaporates and needs constant replenishment, but I'm unclear about what happens to stabilizer over time.

Specifically, does CYA evaporate from the pool like chlorine does, or does it remain in solution indefinitely? If it doesn't evaporate, what are the actual mechanisms for removing excess stabilizer when levels get too high? I need to understand this for proper water balance management.…more
Should You Shock Your Pool Before Winter Closing?

Should You Shock Your Pool Before Winter Closing?

Finally figured out why my neighbor's pool stays crystal clear all winter while mine turned into a swamp last year — is shocking before closing the secret? They're telling me I need to shock before adding winterizing chemicals, but of course they're also trying to sell me their premium shock treatment for twice what I can get it elsewhere.

Is shocking actually necessary before winter closing, or is this just another upsell? If I do need to shock, does the timing matter with when I add the other winterizing chemicals? I'm tired of spending a fortune on pool maintenance when I feel like half of what they recommend is just to boost their profits.…more

How Long Can You Keep a Pool Closed? Complete Guide

During winter I'm trying to decide between keeping my pool closed all season to save on chemicals versus opening it and dealing with the constant money drain from maintenance. Every time I go to the pool store they're trying to upsell me on some expensive treatment or service. I'm thinking about just closing my pool for an extended period to avoid all these costs.

Can I keep it closed for longer than just the winter months? What's the maximum time I can leave it shut down without causing permanent damage? I'd rather do the work myself when I reopen it than keep throwing money at these overpriced pool companies all season long.…more

Do You Remove Skimmer When Closing Pool? Step-by-Step Guide

I opened my weather app to see the first freeze hits this weekend and I'm staring at this skimmer wondering if I need to yank it out or leave it. I know I need to do something with the skimmers, but I'm getting conflicting advice online about what exactly needs to come out.

Do I need to physically remove the entire skimmer unit from the pool wall, or just certain components? I've heard about removing baskets and doors, but I want to make sure I'm not missing anything that could get damaged over winter. Last thing I need is expensive repairs come spring after this disaster of a season.…more

How to Drain Above Ground Pool - Complete Safety Guide

Three different sources are telling me wildly different drain times for my above ground pool — my contractor says 6-8 hours but the pump manual clearly states 2-3 hours maximum. Now they want to charge me $300 just to drain my above ground pool for the winter! That's ridiculous.

I know I can do this myself but I want to make sure I don't mess up my liner or damage anything. What's the safest DIY method to drain it? I've heard about using pumps or some kind of siphon thing, but I don't want to risk doing it wrong and having to buy a whole new pool setup.…more

Do I Need a Pool Pillow for Winter? Complete Guide

Despite being on a tight budget for winter pool closing, I'm wondering if a pool pillow is actually necessary or just another expense I can skip? I've been researching proper closing procedures and keep seeing conflicting information about pool pillows (air pillows). Some sources say they're absolutely critical, while others suggest they're optional accessories.

Specifically, I need to understand whether pool pillows actually provide meaningful protection against freeze damage to pool walls and equipment. My pool is located in an area where temperatures regularly drop below freezing for extended periods during winter months. What's the technical reasoning behind using these pillows, and what risks am I facing if I skip this component of winterization?…more

Do I Need Alkalinity in My Pool? Essential Water Chemistry Guide

Staring at this rental property pool that I've never maintained before and the pH keeps bouncing from 6.8 to 8.2 no matter how much acid or soda ash I add. My pool guy mentioned something about alkalinity being important, but honestly at this point I'm wondering if it's just another way to get me to buy more chemicals.

Do I actually NEED to worry about alkalinity levels, or is it just marketing BS? I'm willing to do whatever it takes to get stable water, but I need to know if this is really going to help or if I'm just wasting more money on chemicals that won't fix my pH roller coaster.…more
