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

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

Can You Clean Pool Filters with Vinegar? Complete Guide

Looked at my pool filter after buying my first house and honestly have zero clue if I need some expensive cleaner or if vinegar works. My cartridge filter has some white buildup on it that looks like calcium deposits, and I've heard people mention using vinegar as a cleaner around the house.

Is it safe to clean pool filters with vinegar? If so, how would I go about doing it? The pool store mentioned something about different types of filters having different cleaning methods, so I want to make sure I don't damage anything. Any guidance would be really appreciated!…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 You Pressure Wash Pool Filters? Safe Cleaning Guide

Between my pool party this Saturday and getting completely conflicting advice on pressure washing cartridge versus DE filters, I'm running out of time to figure this out.

My current setup includes cartridge filters, but I'm considering switching to either DE or sand filtration depending on cleaning requirements.

What are the specific limitations and recommended procedures for pressure washing each filter type? I want to ensure I'm using appropriate PSI settings and techniques to avoid damaging the filtration media while achieving optimal cleaning results.…more

DIY Pool Maintenance: Complete Guide for Beginners 2026

My newly inherited pool reeks of harsh chemicals and has this slimy algae scum floating on top, and I'm completely clueless about where to even begin. The previous owners left me with a bunch of chemicals and equipment but no instructions. My neighbors keep telling me I need to hire a pool service, but I'm wondering if I can figure this out on my own?

I'm pretty handy with other home maintenance stuff, but pools seem like they might be more complicated? What would I actually need to learn and what tools/supplies should I have on hand? Really trying to avoid turning my beautiful pool into a green swamp this summer!…more

Can You Reuse Pool Filter Sand? Cleaning vs Replacement

Halfway through another messy backwashing session with my gunky 3-year-old sand filter, I'm trying to decide between cleaning it again or just replacing the sand entirely. The sand looks pretty gunky when I backwash, but replacement sand isn't cheap. I've heard some people say you can rinse it thoroughly and reuse it, while others insist fresh sand is the only way to go. What's the real deal here? I don't mind doing the work myself if it'll save some money, but I also don't want to compromise my water quality.…more

Do Sand Pool Filters Need Cleaning? Complete Maintenance Guide

Apparently the manual says to backwash my sand filter every few weeks, but that doesn't match what the pool store is telling me about maintenance. I have a sand filter system and the pool store told me I'd need to clean it sometimes, but they didn't really explain how often or what that involves.

I've been running the filter daily and the water looks pretty good so far, but I want to make sure I'm not missing something important. Should I be doing something regularly to keep the sand filter working properly? And how long does the sand itself typically last before it needs to be replaced?…more

How Long Above Ground Pool Filters Last - Complete Guide

Got called out by my husband for never replacing our pool filter in three years and now I'm wondering if that's why our water keeps getting cloudy. Got an above ground pool and want to know how long each type lasts before I'm throwing money away.

Specifically looking for info on cartridge, sand, and DE filters. When do you actually need to replace vs just clean? Don't want to replace too early but also don't want nasty water.…more

Do I Need to Shock My Pool in Winter? Complete Guide

Between the musty, swamp-like stench seeping through my pool cover and that weird chemical smell hitting me every time I walk by, I'm wondering if I should still be shocking it this winter.

I have a 20,000 gallon inground pool that I keep open year-round here in the Southeast, but I've heard conflicting advice about whether I need to shock as often in winter as I do in summer.

Right now my water temperature is around 55°F and my free chlorine levels have been holding steady at about 2.5 ppm. During summer I was shocking every two weeks religiously, but with the cooler temps and less usage, I'm wondering if I can scale back. Does the type of pool setup (open vs closed for winter) make a difference in shocking frequency? And should I be adjusting based on water temperature or just stick to my summer routine?…more

Do I Need a Pool Skimmer? Essential Equipment Guide

Spent the morning staring at my new pool setup and realized I can't tell which equipment is actually essential versus just expensive extras. The skimmer seems like it would be helpful for picking up leaves and stuff, but I'm wondering if it's something I actually NEED or if I could get by without one to save some money.

I keep seeing them mentioned everywhere but nobody really explains if they're required or just recommended. Are there any safety issues or code requirements I should know about? Just want to make sure I'm not skipping something important that'll cause problems later!…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.

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
