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

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 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

How Is Pool Chlorine Made? Complete Manufacturing Guide

Always assumed pool chlorine was just bleach in a fancy package until my chemistry teacher neighbor said it's actually manufactured completely differently. Now I'm curious — what exactly goes into making pool chlorine and is there really a difference between the cheap and expensive stuff?…more

What Are Chloramines in a Pool? Causes & Fixes

My backyard pool has developed a really strong chemical smell, my kids come out with red burning eyes every single time they swim, AND a neighbor mentioned my chlorine levels might actually be too low despite the overpowering odor — all at the same time. I test my water regularly and I keep adding chlorine, so I'm confused why it smells so strong and still seems to be underperforming as a sanitizer.

Someone at the pool store told me what I'm smelling isn't really chlorine at all — it's something called chloramines or 'combined chlorine' — and that this actually means my free chlorine is being used up and isn't working properly. That really surprised me because I always assumed the strong smell meant there was too much chlorine in the water.

Can someone explain exactly what chloramines are, where they come from, and what I need to do to get rid of them? I want to understand the chemistry so I'm actually solving the problem and not just dumping in more product that won't help.…more

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

Does Pool Chlorine Make You Darker? Skin Effects Explained

During my latest pool investigation, I've got my detective gear ready to figure out why my kids keep coming home darker after swim days — is chlorine actually changing their skin color? They're in the pool for hours during summer camp, and I want to make sure the chemicals aren't harming their skin or causing any unwanted changes.

Is chlorine known to darken skin, or could there be another explanation? I'm also concerned about whether the pool chemicals might be making their skin more vulnerable to other effects from being outdoors so much.…more

Do Salt Water Pools Use Chlorine? The Complete Truth

Since getting my salt water pool, I've been too embarrassed to ask this probably obvious question: does it actually use chlorine or not? Some say salt water pools are chlorine-free, others say they still have chlorine. Which is it?

Looking at switching from traditional chlorine but want to understand what I'm actually getting into. Does the salt system eliminate chlorine completely or not?…more

Tried avoiding pool chemistry for years but finally planning to tackle understanding how chlorine actually works this Saturday — what basics should I have down first?

Can Pool Chlorine Make You Itchy? Causes & Solutions

Finally planning to tackle my itchy pool problem this Saturday — need to figure out why my arms and shoulders keep getting irritated despite maintaining 2-3 ppm free chlorine in my 20,000-gallon inground pool. I maintain pH around 7.4 and alkalinity at 100 ppm, so the basic chemistry seems fine. The itching mainly affects my arms and shoulders where I spend the most time in the water.

I'm wondering if there's something I'm missing about chlorine that could be causing this skin irritation. I shock the pool weekly with calcium hypochlorite and use trichlor tablets in my skimmer, but the itchy feeling has gotten worse over the past month. Could it be the chlorine itself making me react this way, or is there another water chemistry issue I should be looking into? I've tried moisturizing after swimming but that only helps temporarily.…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.

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 Pools Have Chlorine? Pool Sanitization Methods Explained

Three weeks ago my wife mentioned that she could smell chlorine around our pool area and it got me thinking - do all pools actually contain chlorine? I always assumed they did but now I'm second-guessing myself. We have a basic above-ground pool and I've been adding chemicals but honestly I'm not 100% sure what's in them or if chlorine is definitely one of the ingredients. My wife is concerned about the kids swimming in chlorinated water and wants to know if there are pools that don't use chlorine at all. I feel pretty clueless about what's actually keeping our water clean.…more
