Can Pool Heaters Be Repaired? Complete Repair Guide 2026

Pulled three quotes ranging from $600-$900 to fix my 8-year-old gas pool heater that won't heat and wondering if I can DIY this myself. The pilot lights but water temp barely rises. Not sure if it's the thermostat, heat exchanger, or something else.

Is it worth getting it repaired at this age? What kind of problems can actually be fixed vs when you should just buy new? Don't want to throw money at repairs if replacement makes more sense.…more

Above Ground Pool Problems: Complete Troubleshooting Guide

Our above ground pool faces the exact same maddening issues every single spring, and we're tired of getting ripped off by overpriced pool store "solutions. Between overpriced chemicals and costly service calls, I'm looking to become more self-sufficient with pool maintenance.

My pool seems to have different issues throughout the season - sometimes the water looks off, other times the pump isn't working right, and occasionally I notice problems with the liner or walls. Rather than guessing or getting upsold every time, I'd love a systematic way to figure out what's actually wrong so I can tackle these problems myself and save some money.…more

Can a Pool Sand Filter Be Too Big? Sizing Problems Explained

During our weekly pool maintenance routine, my husband casually mentioned that our 15,000 gallon inground pool's water has looked consistently cloudy despite my best filtration efforts, and now I can't stop obsessing over what's wrong. The water isn't cloudy exactly, but it lacks that crystal-clear sparkle and seems to have a slight haze that won't go away. My chemical levels are all in range - chlorine at 2.5 ppm, pH 7.4, alkalinity 110 ppm, and I've shocked multiple times with no improvement.

I recently upgraded to a larger 24-inch sand filter thinking bigger would be better, but I'm starting to wonder if I made a mistake. My pump runs at about 45 GPM, and I've noticed that when I backwash, the water doesn't seem to flow very forcefully compared to my old smaller filter. Could the filter actually be too large for my system? I've heard that oversized filters can cause problems, but I'm not sure how to tell if that's what's happening here.…more

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 pH Be Too High? Problems & How to Lower It

Between my pool test strips screaming dangerously high pH and my kids' eyes burning like fire every swim, something's definitely not adding up here. I tested it yesterday and it's reading around 8.0, which seems higher than normal. The water also looks a bit cloudy even though I've been adding chlorine regularly.

I'm concerned about whether it's safe for the kids to keep swimming. What problems does high pH actually cause, and how can I bring it down safely? I want to make sure the water quality is good before they get back in the pool.…more

Pool Shock vs Chlorine: Do You Need Both? Complete Guide

Planning my spring pool opening, the same pushy sales pitch starts at the pool store — they insist I need chlorine tablets AND shock treatment AND algaecide. My pool maintenance costs are getting out of control.

Do I really need to buy separate shock products if I'm already using chlorine for regular sanitization? I'm starting to think they're just trying to squeeze more money out of me. Can't I just use one product that does both jobs? I'd rather go the DIY route and simplify my chemical routine if possible.…more

Does My Pool Need Phosphate Remover? Complete Guide 2026

I tried everything to prevent algae blooms, but my pool only gets green when temperatures hit 85°F or higher—my pool store insists phosphate remover is the solution.

My pool currently has balanced pH and alkalinity, and I maintain chlorine at recommended levels. I'm wondering if phosphate removal should be a regular part of my maintenance routine, or if there are specific conditions where it becomes necessary. What's the technical perspective on when phosphate removers actually provide measurable benefits versus when they're just an additional expense?…more

Can You Shock Pool With Liquid Chlorine? Complete Guide

Replaced my pool's chlorine tablets with liquid this season — planning to shock my 10,000 gallon pool Saturday, what supplies do I need ready? Have liquid chlorine on hand but not sure if it's effective for shocking or if I need granular shock instead.

How much liquid chlorine would I need to properly shock? Want to raise chlorine levels by about 10ppm.…more

How Pool Algaecide Works: Complete Chemistry Guide 2026

I replaced three different algaecides in two months, my 20,000-gallon pool still gets green spots weekly, AND my perfect chlorine levels aren't preventing anything. I've tried copper-based and polyquat algaecides, but I'm curious about the actual chemistry behind how these products work to kill algae.

My current chlorine levels are around 2-3 ppm and pH is 7.4, but I still get green spots forming on the walls every few weeks. The pool guy says algaecides work differently than chlorine, but he couldn't explain exactly how. I'd love to understand the science behind what's happening at the cellular level when algaecide contacts algae, and whether I should be relying more on higher chlorine levels or these specialty chemicals for prevention and treatment.…more

Do I Need to Drain My Green Pool? Step-by-Step Solution

Despite my husband insisting our algae-covered pool "looks like a swamp that needs to be drained," I'm wondering if the pool store's costly advice is actually necessary. The local pool store is telling me I need to drain the whole thing and start fresh, which sounds incredibly expensive and wasteful. They're also trying to sell me a bunch of expensive chemicals and treatments.

I've been reading about DIY methods like the SLAM process but I'm not sure if that actually works or if I'm just wasting time. Has anyone successfully cleared a green pool without draining? I'm tired of throwing money at this problem and would love to know if there's a realistic way to fix this myself without the nuclear option of starting over.…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.

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
