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

How Pool Chlorine Works: Complete Chemistry Guide 2026

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? I know chlorine kills bacteria and algae, but what's actually happening at the molecular level? Does pH really matter that much for it to work properly?

Also keep hearing about cyanuric acid affecting chlorine effectiveness. How does all this chemistry actually fit together?…more

Can Pool Chlorine Bleach Clothes? Fabric Protection Tips

Nobody warned me about how intense the chlorine smell would be around my pool area after adding shock last night. The chemical odor is really strong this morning, and I'm worried about hanging laundry on the nearby clothesline or even just walking around the pool deck in my good clothes. I can practically taste the chlorine in the air. Will exposure to pool chlorine fumes or splashing actually bleach and ruin fabric? My wife is already upset that I got some pool water on my shirt yesterday and now there's a light spot on it.…more

Can Pool Heaters Explode? Safety Guide & Prevention Tips

Standing outside after last week's downpour, I keep hearing these weird clicking sounds from my pool heater and now I'm paranoid it might actually explode. Is there actually a real risk of these things exploding, or am I just watching too much news?

I do the basic maintenance but honestly don't know much about the safety side of things. What should I be looking out for to keep my family safe? And how often do pool heater explosions actually happen - is this something I need to lose sleep over or just stay on top of with regular checkups?…more

Are Borates Actually Worth Adding to My Pool?

Nobody at the pool store seems to give me a straight answer about borates — they either push every product on the shelf or just shrug. My water has this slightly harsh, almost sharp smell to it after I shock, and I keep reading that borates can help with that kind of thing. But I honestly don't understand what they actually do chemically, or whether they're going to create more work for me than they're worth. Is this one of those optional 'nice to have' additions, or am I missing something that would genuinely make a difference in how the water feels and behaves?…more

Do Pool Chlorine Tablets Expire? Complete Shelf Life Guide

Walked into the garage yesterday and my wife called out my "chlorine tablet graveyard" from 2022, making me wonder if those old tablets are even safe to use.

The pool store guy keeps telling me I need fresh chemicals every year, but that seems like a money grab. How long do these tablets actually last, and how can I tell if mine have gone bad? I'm trying to save money by buying in bulk and storing extras, but I don't want to use something that could be dangerous or just won't work properly.…more

Should I Turn Off Salt Cell When Shocking Pool? Complete Guide

Staring at my salt cell wondering if I need to turn it off before shocking my pool — can't afford a $200 service call right now.

Should the salt chlorine generator be turned off while administering shock treatment, or can it continue running?

I want to ensure I'm following correct procedures to avoid any potential equipment damage or interference with the shock's effectiveness. What's the standard protocol for salt cell operation during chemical shock applications?…more

Does a Chlorine Pool Clean You? Sanitizing Effects Explained

Pulled every trick in the book — tested water chemistry, scrubbed surfaces, shocked twice — but still can't figure out if my 20,000 gallon chlorinated pool actually cleans me. My family swims regularly, and I've been wondering about the actual cleaning effects of chlorinated water on our bodies. I know chlorine is designed to kill bacteria and sanitize the pool water, but does it provide any real sanitizing benefits to swimmers?

Specifically, I'm curious whether the chlorine concentration in properly maintained pools is sufficient to kill germs and bacteria on our skin while we swim. My kids often come out of the pool and think they don't need to shower because "the pool cleaned them," but I'm not sure if that's actually true. Does chlorinated pool water provide genuine sanitizing effects on the human body, or do we still need regular soap and water for proper hygiene after swimming?…more

Can I Use Pool Chlorine Tablets in My Well? Safety Risks

Opened my well disinfection system this morning to find it's eating through expensive treatment bottles way faster than it should, while I've got pool chlorine tablets collecting dust.

Seems like such a waste when I already have pool chlorine tablets at home. Can't I just drop a few of those trichlor tablets down my well to disinfect the water? I'm looking for a simple DIY solution that doesn't involve buying more overpriced chemicals.…more

Do Salt Water Pools Need Chemicals? Complete Guide

Our saltwater pool area reeks of that sharp chlorine smell every morning, which seems impossible since we were told these systems are basically chemical-free.

But now I'm reading conflicting information online. The pool store told me I'd still need to buy some chemicals, but I'm confused about what exactly. I thought the salt system was supposed to handle everything? What chemicals do salt water pools actually need, and why? I want to make sure I'm taking proper care of the pool and keeping the water safe for my family.…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

Can Pool Heaters Catch Fire? Safety & Prevention Guide

Already found the perfect pool heater online but these fire horror stories have me second-guessing — am I overthinking this or dodging a real bullet? The pool store guy was trying to sell me on some expensive professional installation package, claiming heaters can be dangerous if not done right. Of course he's pushing the pricey option.

But seriously, can these things actually catch fire? I'm handy with DIY stuff and tired of getting gouged by pool stores, but I don't want to mess around if there's real fire risk involved. What are the actual dangers with gas vs electric heaters, and what should I watch out for to prevent problems? I'd rather know the facts than get sold another overpriced service.…more

Should You Shock Pool When Chlorine Is Already High?

Called my pool guy about my 8-year-old chlorination system that's overdosing — should I shock anyway or risk algae growth? My pool's total chlorine reading is showing high levels, but I'm uncertain whether shocking is still necessary or potentially harmful in this situation.

Specifically, I want to understand the relationship between total chlorine, free chlorine, and combined chlorine levels when determining shock treatment protocols. What's the proper testing sequence and decision matrix for shock treatment when initial chlorine readings appear elevated?…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

How to Shock a Pool: Complete Step-by-Step Guide

Pulled my test strips this morning showing 0.5 ppm after shocking last night, but every guide says it should be reading at least 10-12 ppm. I've tried dumping some shock granules in a few times but the water still doesn't look great and I'm worried I might be wasting chemicals or even making things worse. What's the actual step-by-step process for shocking a pool properly? When should I be doing this and how much should I use? I have a 20,000 gallon inground pool if that matters.…more
