Does Pool Algae Consume Chlorine? Understanding Chlorine Loss

About every time the temperature hits 85°F outside, my pool's chlorine levels nosedive to almost nothing, but stay rock solid during cooler days. I'm adding the same amount of chlorine I normally do, but it seems like it's disappearing quickly. A friend mentioned that algae might actually be 'eating' or consuming the chlorine somehow. Is this actually what's happening? I'm trying to understand the science behind it so I can tackle this problem more effectively. Should I be adding more chlorine, or is there a different approach I should take?…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

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 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

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

Can I Shock Pool After Adding Algaecide? Complete Guide

Spent all morning watching my pool turn green with algae patches and now I'm holding bottles of algaecide and shock with no clue which to use first. But I'm not sure about the timing - can I add both in the same day? Should I put the algaecide in first, or does it matter?

Also, if I can use both, how long should I wait between adding them? Don't want to mess up my water chemistry or waste expensive chemicals by doing this wrong!…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

Do Pools Need Chlorine? Essential Pool Sanitizer Guide

Between my neighbor claiming pools don't need chlorine with proper balance, the pool store insisting it's essential, and YouTube giving conflicting advice, I'm completely lost.

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 Saltwater Pools Need Chemicals? Yes - Here's What You Need

Despite having a 15,000 gallon saltwater pool with a functioning salt system, the pool store keeps pushing $200+ worth of chemicals every month. They keep telling me I need all these pH adjusters, alkalinity boosters, and other expensive stuff on top of the salt. I thought the whole point of going saltwater was to avoid dealing with a bunch of chemicals!

I'm looking to handle this myself and cut down on costs, but I want to make sure I'm not missing something important. Does the salt chlorine generator really only make chlorine? What other chemicals do I actually NEED to keep my water balanced, and what can I skip?…more
