Can Pool pH Cause UTI? Pool Water Chemistry Health Risks

Since I can't afford a doctor visit right now, could my pool's screwed up pH levels actually be causing these recurring UTI symptoms? My family has been swimming a lot, but my daughter got a UTI recently and now I'm paranoid about whether it could be related to the pool water.

The pool store told me my pH was running a bit high last month, and I've been struggling to keep my chlorine levels consistent. I'm wondering - can high pH directly cause UTIs, or is it more about the overall water quality? I want to make sure our pool is safe for everyone to swim in, but I'm not sure if I should be worried about the pH specifically or if there are other factors I should focus on first.…more

When to Change Sand in Pool Filter: Complete Guide 2026

Halfway through the pool season and my sand filter is already eating through replacement sand way faster than it should. The filter has been in operation for approximately two years, and I want to determine the optimal replacement interval for the sand media to ensure consistent filtration performance.

Specifically, I'm looking for technical guidance on the expected service life of pool filter sand, what operational indicators suggest replacement is necessary, and how deteriorated sand affects overall system efficiency. My current setup maintains proper chemical balance, but I want to stay ahead of any filtration issues that could compromise water quality.…more

Do I Need a Pool Vacuum? Complete Equipment Guide 2026

Wondering if anyone else had their manual skimming routine work perfectly on their old above-ground pool but this inground one still looks swampy? I've been trying to maintain it with just skimming and brushing, but there's always debris settling on the bottom that I can't seem to get rid of. My neighbors keep telling me I need some kind of vacuum, but I have no idea what type would actually work for my setup.

I have a medium-sized inground pool that gets a decent amount of leaves from the trees overhead, especially in fall. I'm willing to put in some manual work if it saves money, but I also don't want to be out there for hours every week. What should I be looking for in a pool vacuum, and do I really need one or are there alternatives that actually work?…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

Do I Need to Clean My Pool Before Closing? Winter Prep Guide

Apparently my spring pool opening is eating through way more cash and weekends than it should because I keep screwing up these same winter prep steps. My pool has been maintained throughout the summer, but I'm uncertain about the specific cleaning requirements before adding winterizing chemicals and covering.

What are the essential cleaning steps I must complete before winterization? I'm particularly concerned about preventing algae formation and protecting my equipment from potential damage during the closed season. Should I focus on debris removal, water chemistry adjustment, or are there additional cleaning procedures that are critical for a successful spring reopening?…more

Can Pool Algae Be Brown? Types, ID & Treatment Guide

According to my pool guy I've done everything right — shocked twice, scrubbed every surface, ran the pump nonstop — but this mysterious brown crud keeps coming back. I know green algae is the usual suspect, but this stuff is definitely more brown/yellowish. Is that even a thing with pool algae?

I'm trying to figure out if I need to shock it like regular algae or if there's some other treatment I should be doing. Don't want to waste a bunch of chemicals if I'm treating the wrong problem!…more

Can Pool Algae Be White? Types & Treatment Guide

The white slime on my pool walls tripled in size after I followed three different YouTube cleaning tutorials. I've been treating it like regular green algae - shocked it multiple times, balanced my chemicals, the whole nine yards. But this white stuff just keeps coming back and it doesn't look like any algae I've dealt with before.

Is white algae even a thing? Or am I dealing with something completely different here? The texture is almost... fluffy? And it seems to stick to surfaces more than regular algae. I'm starting to think I need a different approach but I don't want to keep throwing chemicals at the wrong problem.…more

How to Clean Pool Liner: Complete Above Ground Pool Guide

Three days until our big pool party and I'm staring at an above ground pool liner that looks absolutely revolting. The liner is starting to look a bit grimy and I can see some algae spots forming near the waterline. The pool store told me I need to clean it regularly but didn't give me specifics on how to do it safely.

I'm worried about damaging the vinyl since it wasn't cheap to replace. What kind of cleaner should I use, and what's the proper technique? I have a regular scrub brush but I'm not sure if that's too harsh. Should I be checking my water chemistry first before cleaning? Any guidance would be really appreciated since I don't want to mess this up!…more

How Long Can You Keep a Pool Closed? Complete Guide

During winter I'm trying to decide between keeping my pool closed all season to save on chemicals versus opening it and dealing with the constant money drain from maintenance. Every time I go to the pool store they're trying to upsell me on some expensive treatment or service. I'm thinking about just closing my pool for an extended period to avoid all these costs.

Can I keep it closed for longer than just the winter months? What's the maximum time I can leave it shut down without causing permanent damage? I'd rather do the work myself when I reopen it than keep throwing money at these overpriced pool companies all season long.…more

How Solar Pool Heaters Work: Diagnosis & Troubleshooting

According to what I spotted this morning, my solar heater panels are just sitting there doing absolutely nothing while every "expert" keeps pushing gas systems instead. They keep pushing these pricey gas heaters and telling me solar is "complicated" - probably because there's less markup for them.

I want to understand the actual process of how solar pool heaters function before I make any decisions. Do they really just use the sun's energy somehow? I'm hoping to find a more cost-effective heating solution and maybe even explore some DIY options instead of getting ripped off again.…more

Can Salt Water Pools Cause UTI? Pool Safety & Prevention

During my first summer with a salt water pool, I keep getting UTIs and have absolutely no clue if the pool could be causing them. Family swims daily but I'm paranoid about UTIs. Do salt water pools actually cause urinary tract infections or is that just a myth?

What chlorine levels should I maintain to keep everyone safe? Pool store guy said 2-4 ppm but want to double check before letting the kids swim more.…more

Can I Shock Pool in Morning? Best Timing & Step Guide

Called my neighbor who shocks his pool every morning with crystal-clear results, but everyone insists I should only do it at night — what's the real deal? Is there any real problem with shocking in the morning? I've got liquid chlorine on hand and don't mind checking the chemicals more often if needed. Just want to make sure I'm not wasting time or chemicals by doing it when the sun's out!…more
