Do I Need DE in My Pool Filter? Diagnosis & Solutions

I turned to three different pool techs about my 2019 Pentair FNS Plus cartridge system and got three completely different answers about adding DE. My kids spend hours in the pool every day during summer, and I want to make sure the water is as clean and safe as possible for them.

I'm honestly not even 100% sure what type of filter system we have - the previous homeowner left some DE powder in the pool shed, but I don't know if I'm supposed to be using it or not. How do I figure out if my specific filter needs DE, and if so, what's the right way to add it? I just want crystal clear water that's safe for my children to swim in every day.…more

Can You Run Pool Pump Without Filter? Risks & Solutions

Somewhere between my husband questioning why our pool pump is running without a filter cartridge and my growing panic, I'm wondering if I'm actually damaging something. My filter cartridge is completely clogged and I need to replace it, but my kids are asking to swim this afternoon. I'm wondering if I can just run the pump without any filter for a few hours until I can get to the pool store.

I know this probably isn't ideal, but would it cause any serious damage to the pump or create unsafe water conditions? I don't want to risk my children's safety, but I also don't want to damage our equipment if there's a way to manage this temporarily.…more

Do Salt Water Pools Stay Clean? Complete Maintenance Guide

Already three weeks into this rental with a salt water pool I've never maintained before and getting nasty algae blooms plus cloudy water. My generator is running fine and producing chlorine, but somehow I still have to test chemicals, brush walls, and fight green water.

What am I missing here? Does the salt water system actually keep the pool clean on its own, or is there still a bunch of regular maintenance I need to be doing? I feel like I got sold a bill of goods about how "easy" salt water pools are supposed to be.…more

How Long Do Above Ground Pool Pumps Last? Lifespan Guide

The weird grinding noises coming from my above ground pool pump have me worried it's dangerous - with my kids swimming daily, could this thing fail completely and hurt someone? My current setup is a 24-foot round pool (about 13,500 gallons) that gets moderate use during our 5-month swimming season. I maintain proper chemical balance with chlorine levels around 1-3 ppm and pH between 7.2-7.6.

I'm particularly interested in whether there's a significant difference in longevity between budget pumps (around $200-300) versus higher-end models ($500-800). My current pump is about 4 years old and starting to make some noise, so I'm wondering if I should be preparing for replacement soon or if it might have several more years left. What factors most affect pump lifespan - is it mainly about build quality, or does maintenance and usage patterns play a bigger role?…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

How Long Do Pool DE Filters Last? Complete Lifespan Guide

Pulled the cover off my DE filter system today and got hit with this awful musty, stagnant smell after 18 months of running it on my 20,000-gallon pool. I've been adding fresh DE powder every few weeks after backwashing, but I'm not sure how long the actual filter grids are supposed to last before they need to be completely replaced.

Lately I've noticed that my filter cycles seem to be getting shorter - I'm having to backwash more frequently than I used to, and the water clarity isn't quite as crystal clear as it was when the system was newer. My pool gets moderate use with about 4-6 swimmers regularly, and I keep my chlorine around 2-3 ppm and pH at 7.4. Are these signs that my grids are wearing out, or is this normal aging? What's the typical lifespan I should expect from DE filter components?…more

Can You Keep a Pool Clean Without a Filter? Complete Guide

Staring at my pool manual that insists I need a filter system, but I'm seeing other pool owners somehow maintaining crystal-clear water without one. I'm Nancy T. and I'm completely new to pool ownership - just inherited my grandmother's old above-ground pool. I noticed the filter system seems to be broken or missing some parts, and I'm wondering if there's any way to keep the water clean without it? Maybe I'm being naive, but I thought I'd ask before spending money on repairs. I've been adding chlorine tablets like the neighbor suggested, but I'm not sure if that's enough. Please be patient with me - I really don't know much about pool maintenance yet! Any advice would be greatly appreciated.…more

How to Clear Cloudy Pool Water: Complete Step-by-Step Guide

Pulled off a perfect shock treatment on my old above-ground pool for this exact cloudy water mess, but my new inground pool still looks like milk. I can barely see the bottom and it's honestly embarrassing with summer parties coming up.

I'm pretty sure I need to do something with the chemicals and maybe run the filter more, but I have no idea what the right steps are or how long this is going to take. Should I be testing the water first? Adding chlorine? Help me get my pool back to that beautiful clear blue!…more
