Do Fiberglass Pools Need Calcium Hardness? Complete Guide

Pool builder says my new fiberglass shell doesn't need calcium hardness adjustments like a plaster pool does. But the water test shows 150 ppm and the internet says that's too low for any pool. Who's right here — does fiberglass actually need calcium or not?…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

How Long Do Automatic Pool Covers Last? Expert Analysis

Every summer when temps hit 85°F my automatic pool cover starts jamming halfway across my 16x32 rectangular pool — works perfectly all winter long. My pool is rectangular, about 16x32 feet, and I'm handy with tools so I'm planning to do the installation myself. I've been researching different brands and materials, but I can't find consistent information about how many years these systems typically last before needing major repairs or replacement. I want to factor in the long-term costs - not just the upfront purchase price. Are there specific components that wear out faster than others? I'd also like to know if there are maintenance tasks I can do myself to extend the lifespan.…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

Do You Need Cyanuric Acid in a Saltwater Pool? Complete Guide

Somewhere around midnight my saltwater pool's chlorine levels just crashed — need to figure out if cyanuric acid will fix this before the pool guy comes tomorrow. The pool store keeps pushing me to buy their stabilizer products, claiming it's essential, but I'm suspicious they're just trying to upsell me on expensive chemicals I don't really need.

I thought the whole point of having a salt system was to avoid all these extra chemical additions and maintenance headaches. My chlorine generator seems to be working fine, so do I really need to spend money on cyanuric acid? What levels should I be targeting if it's actually necessary, and can I add it myself instead of paying pool store prices?…more

Can Pool Leak Through Hydrostatic Valve? Detection & Repair

According to my pool's behavior, the water level started dropping steadily yesterday even though nobody's been swimming, and now I'm wondering if the hydrostatic valve is leaking. The water level drops consistently even when the pool isn't in use, and I've already ruled out obvious surface leaks around the skimmers, returns, and visible plumbing.

From my understanding, hydrostatic valves are designed to prevent the pool shell from floating during high groundwater conditions, but I'm wondering if they can work in reverse - allowing pool water to escape when groundwater levels are low or if the valve mechanism fails. The water loss seems to correlate with our recent dry spell, which has me questioning whether the valve could be stuck open or damaged.

Is it technically feasible for a hydrostatic valve to cause pool water leakage, and if so, what specific failure modes should I be looking for during inspection?…more

How Long Pool Chemicals Take to Settle - Complete Guide

Halfway through adding my pool chemicals, they're just floating on the surface for hours instead of dissolving like they normally do. After adding chemicals like chlorine, pH adjusters, or alkalinity increasers, I want to ensure they're properly mixed before taking water samples for testing.

My pump runs approximately 6-8 hours daily, and I'm concerned about getting inaccurate readings if I test too early. What's the standard circulation time required for different types of pool chemicals to fully distribute throughout the water? I want to establish a proper testing protocol to avoid chemical imbalances.…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

Can You Pre-Dissolve Pool Stabilizer? Complete Guide

Every time my neighbor dissolves his cyanuric acid in a bucket first it works perfectly, but when I dump mine straight into my pool it takes forever — what am I missing?

I've heard that pre-dissolving chemicals helps them work better and faster, but I want to make sure I'm doing it right. Does anyone know if this actually works with pool stabilizer? I'd rather take the DIY approach and save some money instead of getting ripped off by the pool store again.…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

Does Pool Stabilizer Go Away? Understanding CYA Depletion

This is the third time this season my cyanuric acid levels have mysteriously dropped after being perfect all spring and I'm done guessing what's happening. Now I'm opening for this year and my CYA is reading lower than where I left it. Do I really need to keep adding stabilizer every year, or did I mess up my test somehow?

I thought once you get your stabilizer levels right, you're basically set for life. But apparently that's not the case? Just want to make sure I'm not throwing money at chemicals I don't actually need.…more

Can Pool Chemicals Be Stored Outside in Winter? Storage Guide

Our family is trying to decide between hauling all our pool chemicals into the basement this winter or just leaving them in our unheated garage. We're expecting some pretty cold temps this winter and I'm wondering if I should drag all this stuff inside or if it's fine to leave out there?

I've got the usual suspects - chlorine tablets, shock, algaecide, pH adjusters, some liquid stuff. My neighbor said something about containers cracking but I figured I'd ask here before hauling everything to my basement. Anyone know which chemicals are okay with cold and which ones I definitely need to bring in?…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

Can You Leave Above Ground Pool Up All Year? Winter Guide

Halfway through winter prep I've tried partial winterization, full chemical shutdown, and running it with a heater — but I'm still getting conflicting advice about leaving my above ground pool up year-round.

Is it actually possible to leave my above ground pool up through winter and do the winterization myself? What really needs to be done to prevent damage, and can I skip some of these expensive add-ons they keep pushing? I'd rather invest time than keep throwing money at the pool store every season.…more

How Long Do Above Ground Pool Liners Last in Winter?

This Saturday I'm winterizing my above ground pool — should I have a replacement liner ready given how these brutal Northeast winters destroy them faster than the typical 15-20 years? I've heard that above ground pool liners typically last around 15-20 years, but I'm concerned that our harsh winters here in the Northeast might be shortening that timeframe significantly.

We've been pretty good about winterizing - maintaining proper water levels, balancing chemicals before closing, and using a solid winter cover. However, we still get some pretty brutal cold snaps and ice formation. I'm curious if anyone knows how much winter conditions actually impact liner longevity compared to pools in milder climates. Should I expect to replace my liner sooner than the typical 15-20 year range due to winter stress, even with proper winterization?…more
