Can Pool Chlorine Make You Sick? Health Effects Explained

Opened my pool this season after adjusting pH levels, switching chlorine brands, and getting professional water testing — but my family still gets red eyes and skin irritation after swimming. We've been experiencing eye irritation and some skin redness after swimming, but I'm also worried about not having enough chlorine to kill bacteria and other nasties.

My latest test results show chlorine at around 5-6 ppm, and my CYA is sitting at about 50 ppm. I've been using liquid chlorine and shocking weekly with calcium hypochlorite. Sometimes the chlorine drops really low between treatments, maybe down to 0.5-1 ppm, especially after heavy use or rain.

What's the sweet spot for chlorine levels to avoid both chemical irritation and harmful bacteria? I want to keep everyone healthy but not sure if I should be targeting higher or lower numbers based on my current CYA level.…more

When Does My Pool Need Phosphate Remover? Signs & Testing Guide

Last week I bought my first pool and I'm completely lost trying to figure out if these weird water chemistry readings mean I need phosphate remover. The pool store mentioned something about phosphate removers, but I'm not sure when I actually need to use them. I've been keeping my chlorine levels where they should be, but I'm still dealing with some algae issues that won't seem to go away.

How do I know if phosphates are the problem? Is there a specific level I should be watching for, and what kind of test should I use to check? I want to make sure I'm not just throwing chemicals at the problem without understanding what's really going on.…more

Does Pool Chlorine Lighten Hair? Chemistry & Protection Tips

Between being a total pool newbie and having no clue about proper chlorine levels, I'm wondering if I'm accidentally bleaching my hair every time I swim. My daughter has been swimming almost daily and I swear her brown hair is starting to look lighter, almost with blonde streaks. Is this actually happening or am I imagining things?

The pool store told me to keep my chlorine levels between 1-3 ppm, and I've been pretty good about testing and adding chemicals. But now I'm wondering if the chlorine is actually bleaching her hair? If this is really happening, is there anything I can do to prevent it while still keeping the pool safe to swim in?…more

Do Saltwater Pools Need Chlorine? The Complete Truth

About two weeks into this rental with my first saltwater pool and the generator's been running constantly but the water stays green no matter what I do. I've thrown every chemical I can think of at this thing - algaecide, shock, clarifier - and nothing's working.

Do saltwater pools actually need regular chlorine added, or am I missing something else? I thought the whole point was that the salt system makes its own chlorine automatically. My levels seem off but I'm not sure if I should be manually adding chlorine to a saltwater pool or if that defeats the purpose entirely.…more

Do Salt Water Pools Have Chlorine? Yes - Here's Why

Already asked my neighbor about her "chlorine-free" saltwater pool, but mine definitely has chlorine — what am I missing here? I have a 20,000 gallon inground pool and I'm considering converting to a salt water system because I thought it meant no more dealing with chlorine chemicals. My neighbor has been telling me that salt water pools are "chlorine-free" and that's why they're gentler on skin and eyes.

But when I was talking to a pool supply store, the guy mentioned something about salt water pools still having chlorine, just generated differently? I'm confused because if there's still chlorine involved, what's the actual difference? I've been manually adding liquid chlorine to my pool for years and my levels typically run around 2-3 ppm, but I'm tired of the constant chemical additions and storage issues.

Can someone explain whether salt water pools actually contain chlorine or not? And if they do, how does that work with the salt system?…more

Do I Need to Shock My Pool Every Week? Complete Guide

Called three pool stores about weekly shock treatments and they're all pushing $15 products, but is this actually necessary or just a sales pitch? My pool has been relatively clear lately and I've been pretty good about keeping up with daily chlorine levels. But then I had one algae outbreak earlier this season and now I'm paranoid about skipping the weekly shock treatment. Is weekly shocking really required, or are there specific situations when I actually need to do it? I want to maintain a healthy pool without going overboard on chemicals.…more

Does My Pool Need Phosphate Remover? Complete Guide 2026

I tried everything to prevent algae blooms, but my pool only gets green when temperatures hit 85°F or higher—my pool store insists phosphate remover is the solution.

My pool currently has balanced pH and alkalinity, and I maintain chlorine at recommended levels. I'm wondering if phosphate removal should be a regular part of my maintenance routine, or if there are specific conditions where it becomes necessary. What's the technical perspective on when phosphate removers actually provide measurable benefits versus when they're just an additional expense?…more

Do Salt Water Pools Need Chlorine? Complete Chemistry Guide

This house came with a salt water pool system that the previous owner left in complete disarray, and I'm totally clueless about maintaining it. The pool store told me that salt water pools are "chlorine-free" which is why I made the investment, but now I'm reading conflicting information online.

Do I actually still need to buy and add chlorine to my salt water pool? I thought the salt system was supposed to handle all of that automatically. I'm worried I might be missing something important for keeping the water safe for my kids.…more

Can You Swim in a Pool with High CYA? Safety Guide

Around two weeks after my CYA hit 80 ppm, my 20,000 gallon inground pool is eating through chlorine way faster than it should. The water looks clear and I've been maintaining my free chlorine at 3-4 ppm, but I'm having to add way more chlorine than usual to keep it there.

My main concern is whether it's actually safe for my family to swim in the pool with these high stabilizer levels. I've read conflicting information online - some sources say high CYA itself is dangerous, while others focus more on the chlorine effectiveness issue. We've got kids who use the pool daily during summer, so I want to make sure I'm not putting anyone at risk.

Should I be keeping everyone out of the water until I can get the CYA levels down, or is it more about making sure I can maintain proper sanitization despite the high stabilizer? I'm trying to figure out if this is an immediate safety concern or more of a long-term maintenance headache.…more

When Can You Swim After Shocking Pool? Safe Wait Times

I noticed the pool at my new rental was cloudy so I shocked it yesterday evening, but now I'm completely lost on when it's safe for my kids to jump back in. The pool store guy said "wait a few hours" but I've read everything from 8 hours to 24 hours online. The chlorine smell is still pretty strong this morning. I used liquid shock (sodium hypochlorite) and added about a gallon to my 20,000 gallon pool. How do I know when the chlorine levels are actually safe for swimming? I don't want to keep the kids out longer than necessary, but I definitely don't want to risk any chemical burns or irritation.…more

How to Test Pool Stabilizer (CYA) Levels: Complete Guide

Called three different pool repair companies for advice on my stubborn chlorine levels, followed their suggestions exactly, but somehow made my pool chemistry even worse — now I'm wondering if my cyanuric acid is completely out of whack.

I've never actually tested for stabilizer before - I didn't even know it was something I needed to check regularly! What's the most accurate way to test cyanuric acid levels? Are there different testing methods, and do some work better than others? I want to make sure I'm getting reliable readings before I start messing with chemical adjustments again.…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

Can You Shock Pool With High CYA? Safe Methods & Solutions

Between liquid chlorine and cal-hypo shock for tackling this algae mess when my cyanuric acid is already sitting at 80-90 ppm. I understand that high CYA reduces chlorine effectiveness, but I'm not sure about the correct approach for shocking under these conditions.

What's the proper methodology for calculating shock dosage when CYA is high? Should I be using a specific FC/CYA ratio, or is there a point where the CYA is too high to shock effectively? I want to ensure I'm using the right amount of chlorine without wasting chemicals or creating unsafe conditions.…more

Do Indoor Pools Need Cyanuric Acid? Pool Stabilizer Guide

Standing in front of my indoor pool with a tight budget — is cyanuric acid actually necessary or can I skip this $30+ expense the pool store keeps pushing? Last time I was there, they insisted I needed cyanuric acid for my indoor pool and tried to upsell me on their "premium stabilizer package" for like $60.

My pool is completely indoors with no direct sunlight hitting it. I've been managing fine without CYA so far, but I'm wondering if there's actually a legitimate reason to use it? I'm all for DIY pool maintenance and cutting out unnecessary expenses, but I also don't want to mess up my water chemistry if stabilizer actually serves a purpose indoors.…more

Do I Need Pool Shock? When and Why to Shock Your Pool

During last week's heavy storms and downpours, my pool water turned cloudy and now I'm worried it's not safe for my kids to swim. My free chlorine levels seem to be dropping, and we've had some heavy rain lately plus the kids and their friends have been using the pool constantly this summer.

I keep hearing about pool shock but I'm not sure when I actually need to use it or what type is best. I just want to make sure the water is properly sanitized and safe for swimming. What are the signs that tell me I need to shock the pool, and how do I do it correctly?…more
