How to Measure Pool Length: Complete Step-by-Step Guide

The pool guy casually mentioned our measurements seemed "off" during his last visit, and now I'm questioning whether I even know how long our pool actually is. I need the measurements for a new cover and some DIY projects, but I'm not paying those ridiculous markups they charge for everything.

I've got a basic rectangular pool but it's got some curved edges at the corners. Should be simple enough to measure myself, right? What's the best way to get accurate length measurements without calling in the pros? I've already spent way too much money on overpriced chemicals this season.…more

Pool Chemistry Points System - Water Balance Made Simple

Somewhere between my pool guy insisting I need a full testing kit and six different chemicals, I'm wondering if there's actually a simpler way to balance my water. My neighbor mentioned something about key "points" in pool chemistry that are most important to focus on, but I didn't catch all the details.

What are the main chemistry points I should be tracking to keep my water balanced? I'd love to know the target ranges so I can stop guessing and actually maintain clear, safe water. Right now I'm just winging it and probably making things more complicated than they need to be!…more

How to Dissolve Pool Stabilizer (CYA) - Complete Guide

I added granular cyanuric acid to my pool and it's just sitting on the bottom instead of dissolving. I have a 20,000 gallon inground pool and my current CYA reading is around 20 ppm - I need to get it up to about 50 ppm. I tried just broadcasting the granules directly into the pool like I do with other chemicals, but they seem to just sink to the bottom and sit there without dissolving much.

I've heard that cyanuric acid is notoriously slow to dissolve compared to other pool chemicals. What's the most effective method to get this stuff into solution? Should I be pre-dissolving it somehow, or is there a specific technique that works better? I want to make sure I'm doing this right and not wasting product or creating hot spots in my pool.…more

Do Vinyl Pools Need Calcium? Complete CH Guide 2026

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

Can I Cover Pool After Shocking? When It's Safe to Cover

Staring at my pool Saturday morning with shock treatment planned — should I have the cover staged and ready to throw back on or do I need to wait?
The guy at the pool store mentioned something about waiting before putting the cover back on, but I honestly didn't catch all the details - there was so much information!

I'm worried about covering it too soon and maybe damaging the cover or something. How long should I wait after shocking before it's safe to put the cover back on? Is there a specific chlorine level I should be looking for? Any guidance would be really appreciated!…more

Can Salt Water Pool Cause Rash? Quick Solutions & Prevention

Tried everything to stop these red, itchy rashes on my kids from our saltwater pool. I thought saltwater pools were supposed to be gentler on skin than regular chlorine pools, so I'm confused about what's causing this. Could it be something wrong with the water chemistry? The pool water looks clear, but I'm wondering if there are invisible issues that could be irritating their skin. What should I be checking for to make sure the pool is safe for them to swim in?…more

Do Inground Pools Need Liners? Complete Guide 2026

Wondering if my pool renovation is draining my savings account because I keep second-guessing whether my inground pool actually needs a liner. My neighbor just had to replace his pool liner after like 10 years and it was a huge hassle, but my other friend says her concrete pool doesn't have a liner at all?

So which types of inground pools actually need liners and which ones don't? And if I do end up with one that needs a liner, how often am I looking at replacing the thing? Trying to figure out the long-term maintenance costs before I commit to anything!…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 to Use a Pool Sand Filter: Complete Step-by-Step Guide

The pool sand filter that worked fine for years started giving me cloudy water last month but now it's completely dead and those expensive pool store fixes aren't working.

Can someone just give me the straight facts on how to actually operate my sand filter? I want to know the basic daily routine, when I should backwash, and how to tell if it's working properly. I'm looking for simple, practical steps I can handle myself without breaking the bank on unnecessary add-ons.…more

How to Tell if Your Pool Pump Isn't Working Properly

This 4-year-old pool pump is turning my once-crystal-clear water cloudy and stagnant — is it worth repairing or should I just replace the whole thing? I'm not super technical when it comes to pool equipment, so I'm not sure what warning signs I should be watching for.

What are the telltale signs that indicate my pump isn't doing its job properly? I want to catch any problems before they turn into expensive repairs or leave me with a swamp instead of a swimming pool!…more

Can Pool Covers Shrink? Prevention & Solutions Guide

Around three seasons ago I had the same shrinking problem with my old vinyl cover and stretching it worked fine — but this new one seems way tighter than last season. The edges don't reach as far as they used to, and I'm having to really stretch it to get it secured properly.

Is this actually a thing that happens? Can pool covers legitimately shrink over time? Mine's been through a pretty brutal summer with tons of sun, and I'll admit I probably didn't store it perfectly last winter. Just want to know if I need to accept that I'm gonna need a new cover or if there's something I could've done differently to prevent this!…more

Pool Filter Runtime: 24/7 vs Scheduled Operation Guide

During my pool maintenance reading, I keep seeing conflicting advice about filter runtime schedules. Some sources say the filter needs to run 24/7 while others mention you can get away with just 8-12 hours daily. My pool is about 20,000 gallons and I'm using a sand filter with a variable speed pump that I installed last season. Right now I have it programmed to run from 6 AM to 6 PM, but I'm wondering if that's enough turnover to keep the water properly filtered and circulated.…more
