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 Damage Eyes? Safety Tips & Prevention

Before I dump more chlorine in my pool, I need to know if I'm about to blind myself since this is my first time handling chemicals. My eyes always get red and irritated after swimming, and I'm wondering if the chlorine levels I'm maintaining could be causing damage. I don't want to pay for expensive pool service calls if I can handle this myself, but I also don't want to risk permanent eye problems. Should I be concerned about chlorine harming my vision, and are there ways to protect myself without spending a fortune on equipment?…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 Pool Chemicals Make You Sick? Health Risks & Prevention

During every swim session, there's an overwhelming chemical burn in my nostrils and my kids emerge with angry red skin while my youngest develops this persistent cough. I've been adding chlorine and other chemicals trying to keep the water clean, but now I'm wondering if I'm creating a different problem altogether.

What kinds of health issues can pool chemicals actually cause? I handle the chemicals myself when balancing the water, and sometimes I notice my eyes watering or feeling irritated afterward. Are there specific symptoms I should watch out for that mean the chemical levels are off? I want to keep the pool safe and clean, but not at the expense of making everyone sick.…more

Can You Use Pool Chlorine to Clean Your House? Safety Guide

About to tackle some serious deep cleaning this Saturday — is it safe to just grab my leftover pool chlorine instead of buying a bunch of specialty household cleaners? The pool store keeps trying to upsell me on expensive specialty cleaners, but I've got plenty of pool chlorine sitting around. I'm wondering if I can just use some of that chlorine to clean my bathroom, kitchen counters, or other surfaces around the house instead of buying separate products.

Is this actually safe to do, or am I asking for trouble? I'd love to find a DIY solution that saves me some money, but I don't want to damage anything or create health hazards. What are the real risks here?…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

Does Pool Filter Sand Type Matter? Complete Sand Guide

Last week my pool guy swore 20-silica sand is all the same, but my filter's clogging in 2 months instead of the 6-month replacement schedule everyone talks about. The guy there was trying to sell me on some fancy zeolite stuff that costs way more than regular sand.

I mean, sand is sand, right? Or does the type actually affect how well it filters and how often I'll need to backwash? Don't want to cheap out if it means dealing with cloudy water all summer, but also don't want to get upsold on something that's just marketing hype.…more

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

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 Pool Shock Works: Complete Chemistry Guide

Spent hundreds on every shock product available, followed instructions perfectly, even doubled doses — but my 20,000 gallon inground pool chemistry still makes zero sense to me. I know it raises chlorine levels temporarily, but what's the chemical process that's actually cleaning my water?

My pool gets a lot of use during summer - kids swimming daily, sunscreen, sweat, the occasional algae bloom if I'm not careful with maintenance. When I shock it, usually with calcium hypochlorite, the water clears up within 24 hours. But I'd love to understand the chemistry of how shock treatment breaks down contaminants and restores water quality. What exactly is happening at the molecular level when those chlorine levels spike?…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

Can I Use Pool Chlorine Tablets in My Toilet? Safety Guide

Standing in my garage with a bucket of leftover trichlor tablets from last season and wondering if these can pull double duty as toilet bowl cleaners. My thinking is that chlorine is chlorine, right? I've seen those blue toilet bowl tablets that slowly dissolve and keep things clean, so I figured maybe I could just drop one of my 3-inch pool tablets in the tank to do the same thing.

Before I try this, I want to make sure it's actually safe for my plumbing and won't cause any problems. Are pool chlorine tablets too strong for toilet use? I don't want to damage my pipes or create any health hazards, but it seems like it could be a good way to use up these extra tablets instead of letting them go to waste.…more

Can You Use Pool Chlorine in Washing Machine? Safety Guide

Despite my pool chlorine testing at 12.5% sodium hypochlorite, my laundry bleach bottle says 6% - can I actually use the stronger pool stuff in my washing machine? My understanding is that both pool chlorine and household bleach contain sodium hypochlorite as the active ingredient, but I need to verify the concentration differences and potential compatibility issues.

Specifically, I'm concerned about whether the higher concentration levels in pool chemicals could cause damage to washing machine components, fabric degradation, or create hazardous chemical reactions when mixed with detergents. What are the technical considerations and safety protocols I should evaluate before attempting this substitution?…more

Can Pool Chlorine Clean Concrete? Safe Methods & Alternatives

Between the humidity and recent rain, my concrete pool deck started showing these nasty green algae stains last week and now I'm wondering if pool chlorine can clean them off. My concrete pool deck is absolutely filthy with algae stains and dirt buildup, and nothing seems to work. I've scrubbed until my arms hurt and tried different cleaners, but these green stains just won't budge.

I have tons of pool chlorine sitting around and I'm wondering if I can use that to blast these concrete stains away? I don't want to damage the surface or create some kind of chemical disaster, but I'm running out of options. If chlorine works, what's the right way to dilute it? And honestly, are there better alternatives that might actually get this mess clean without all the guesswork?…more
