Can Pool Filter Pressure Be Too Low? Diagnosis & Solutions

Found out from my wife that our pool filter pressure gauge has been stuck at a weirdly low 6-7 PSI all week and now I can't stop obsessing over it. My 20,000 gallon inground pool has been running fine otherwise, but I'm wondering if this low pressure is something I should be concerned about.

I've heard people talk about high filter pressure being bad, but nobody ever mentions if pressure can be too low. The pump seems to be running, but I'm not sure if the water flow looks as strong as it used to be. Water chemistry has been balanced - chlorine at 2.5 ppm, pH at 7.4, and alkalinity at 110 ppm. Should I be worried about this low pressure reading, and what could be causing it?…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

How Long to Backwash Pool Sand Filter: Complete Guide

Since it's 11 PM and my sand filter pressure just spiked to dangerous levels — need to backwash this thing before my pump burns out overnight. Right now I'm dealing with my sand filter - the pressure has gone up quite a bit from when I first cleaned it, and I know it's time to backwash.

But here's my question: how long should I actually run the backwash cycle? I don't want to waste a ton of water (my utility bills are already high enough), but I also want to make sure I'm doing it properly. Is there a specific time I should aim for, or some other way to tell when it's done? I'd rather figure this out myself than pay someone else to do basic maintenance.…more

How Pool Vacuums Work: Complete Troubleshooting Guide

Since I'm planning to troubleshoot my pool vacuum this Saturday — should I expect suction-side, pressure-side, and robotic models to need completely different repair approaches? My current setup isn't performing optimally, and I want to diagnose whether the issue stems from suction pressure, mechanical components, or operational methodology.

What are the fundamental working principles behind suction-side, pressure-side, and robotic pool vacuums? I'm particularly interested in the engineering differences between each type and their common failure points. Understanding the mechanics will help me identify whether poor performance is due to inadequate water flow, clogged components, or system-specific malfunctions that require targeted solutions.…more

How to Use a Pool Sand Filter: Complete Step-by-Step Guide

The pool sand filter that worked fine for years started giving me cloudy water last month but now it's completely dead and those expensive pool store fixes aren't working.

Can someone just give me the straight facts on how to actually operate my sand filter? I want to know the basic daily routine, when I should backwash, and how to tell if it's working properly. I'm looking for simple, practical steps I can handle myself without breaking the bank on unnecessary add-ons.…more

Pool Filter Balls vs Sand: Complete Replacement Guide

Noticed my pool filter isn't performing like it used to — can't afford professional service right now, so is switching from sand to filter balls a DIY job under $100? The pool store mentioned they might work better than traditional sand, but I want to make sure before I make the switch.

Are filter balls actually a good replacement for sand in my filter system? I'm curious about things like how well they filter compared to sand, if they're easier to work with, and whether the maintenance routine changes at all. Any guidance would be really helpful!…more

Do I Need a Sand Filter for My Pool? Complete Guide

Since my pool water keeps turning cloudy even after cleaning, is it dangerous for my kids who swim almost daily? My pool has been a constant headache and I'm wondering if switching to a sand filter would solve my problems, or if there are better options out there.

I keep hearing different things - some people swear by sand filters because they're supposedly low-maintenance, others say cartridge or DE filters work better. My pool isn't huge but gets decent use, and honestly I just want something that actually works without me having to mess with it constantly. What's the real deal with these different filter types and how do I know which one would work best for my situation?…more

Does Cloudy Pool Water Mean Algae? Diagnosis Guide

Walked out to my 20,000 gallon inground pool this morning and the crystal clear water from three days ago is now completely cloudy. They've been asking to use the pool, but I'm worried this cloudiness might mean we have an algae problem that could make them sick.

I'm not sure what's causing the cloudiness - could it be algae starting to grow, or might there be other reasons? How can I tell the difference between algae and other issues that cause cloudy water? I want to make sure I properly diagnose what's wrong before letting the kids back in the pool.…more

How Long Can a Pool Be Empty? Safe Duration & Risks

Replaced my old above-ground pool with this inground concrete setup that needs major repairs, but I've never dealt with draining one before and I'm worried about structural damage. The pool will be without water for potentially several weeks while contractors complete the work.

What are the specific time limits before hydrostatic pressure becomes a concern? Are there differences in safe empty duration between inground concrete pools versus above ground pools with vinyl liners? I want to avoid any structural damage or liner issues during this extended maintenance period.…more

Do I Need to Run My Pool Pump Every Day? Complete Guide

Three hours of constant humming from my pool pump has me wondering if that grinding undertone means I'm overworking it or not running it enough. I have a 20,000-gallon inground pool that gets moderate use from my family of four, plus occasional guests on weekends. During the summer months, I've been running the pump about 6 hours per day, but I'm noticing that my chlorine levels seem uneven throughout the pool, and I'm wondering if that's related to insufficient circulation.

I've heard conflicting advice from neighbors - some say 4-6 hours is plenty, while others insist on 12+ hours daily. My pool store recommended 8 hours minimum, but I want to make sure I'm not under-filtering while also being mindful of electricity costs. Does the runtime need to change based on season, bather load, or pool size? What's the sweet spot for maintaining crystal clear water without over-running the system?…more

How Often to Clean a Pool Cartridge Filter

Looked all over for a straight answer on this and got a completely different response from everyone I asked. My neighbor, who's had a pool for twenty years, told me once a season is plenty. The pool store said every month without fail. Then a YouTube video I watched had the guy pulling his cartridge out every single week like it was a religious ritual. I have a standard in-ground pool that gets moderate use — the kids swim most afternoons in summer but it's not like we're hosting swim meets.

The pressure gauge on my filter is sitting around where it normally runs, so it's not screaming at me to do anything urgent. But with conflicting advice coming from every direction, I genuinely don't know if I'm already overdue or totally fine. Is there a reliable method for figuring this out, or is it just one of those things where you have to learn your own pool?…more

How to Find Pool Leak: Complete Detection Guide 2026

Got my pool water level dropping a massive 2-3 inches this week and there's definitely something wrong beyond normal evaporation. My water chemistry is balanced (chlorine at 2.5 ppm, pH 7.4, alkalinity 120 ppm), so I don't think it's a chemical issue causing excessive evaporation.

I suspect there might be a leak somewhere but I'm not sure how to pinpoint the exact location. Should I be checking around the skimmers and return jets first? I've heard about using food coloring to detect leaks but I'm not sure of the proper technique. Also wondering if there's a way to test whether it's a structural leak versus something in the plumbing lines.

What's the most systematic approach to track down where exactly the water is going? I'd rather diagnose this myself before calling in a expensive leak detection service if possible.…more

How to Tell if Your Pool Pump Isn't Working Properly

This 4-year-old pool pump is turning my once-crystal-clear water cloudy and stagnant — is it worth repairing or should I just replace the whole thing? I'm not super technical when it comes to pool equipment, so I'm not sure what warning signs I should be watching for.

What are the telltale signs that indicate my pump isn't doing its job properly? I want to catch any problems before they turn into expensive repairs or leave me with a swamp instead of a swimming pool!…more

How to Deep Clean a Pool Cartridge Filter

Nobody tells you how fast sunscreen and body oils can clog up a cartridge filter. My pressure gauge has been creeping up steadily, and when I finally pulled the cartridges out, the pleats looked genuinely gunky — not just dusty, but greasy and discolored even after I sprayed them down with the garden hose. A neighbor suggested soaking them in Simple Green since it's a degreaser, but I'm nervous about it foaming up my pool water if I don't rinse it out completely.

My current routine is basically just a garden hose spray-down every few weeks, but clearly that's not cutting through the oils and sunscreen buildup. I want to know the full proper process — the right way to hose them down, whether Simple Green or a dedicated pool filter cleaner is the smarter choice, how to handle mineral scale versus greasy residue differently, and how often a real deep clean should actually happen.

Also, someone in my neighborhood group mentioned using a pressure washer to blast the pleats clean, and now I'm second-guessing everything. What should I absolutely avoid doing, and what's the correct method from start to finish?…more
