How Long After Shocking Pool to Add Algaecide? Complete Guide

The pool service guy insists I wait a full 24 hours after shocking before adding algaecide, but that seems excessive when algae keeps spreading. I have two young kids who are eager to get back in the water, and I want to make sure I'm doing this chemical treatment properly.

Should I wait a certain amount of time between the shock treatment and adding the algaecide? I'm also concerned about when the water will be safe for swimming again. What chlorine levels should I be looking for before adding more chemicals, and how do I know when everything is balanced enough for the kids to swim safely?…more

Can I Shock Pool After Adding Algaecide? Complete Guide

Spent all morning watching my pool turn green with algae patches and now I'm holding bottles of algaecide and shock with no clue which to use first. But I'm not sure about the timing - can I add both in the same day? Should I put the algaecide in first, or does it matter?

Also, if I can use both, how long should I wait between adding them? Don't want to mess up my water chemistry or waste expensive chemicals by doing this wrong!…more

Should You Vacuum Pool After Adding Algaecide? Step-by-Step

I looked outside this morning and there's this overwhelming musty, swampy stench hitting me from the pool with chunks of dead algae floating everywhere after adding algaecide two days ago. The water looks like a swamp but at least it's not getting worse.

Should I be vacuuming this stuff up now or waiting longer? I don't want to mess up my filter with all this crud, but I also can't stand looking at this disaster anymore. What's the right timing for vacuuming after algaecide treatment?…more

Do I Need Algaecide in My Pool? Expert Pool Care Guide

I opened three different algaecide advice sources and got three different answers: pool guy says skip it, store says weekly doses, forums are completely split. I see algaecide products at the pool store and some neighbors swear by them, but I'm not sure if it's actually necessary or just extra insurance. Should I be using algaecide regularly, or only in certain situations? I just want to make sure the water quality is safe and clean for my kids to swim in without overdoing it on chemicals.…more

Can Pool Algae Cause a Rash? Health Risks & Prevention

Around noon yesterday I finished scrubbing down my pool walls but this morning there's green stuff growing back — could this algae be what's causing the rash on my arms?

How Pool Algaecide Works: Complete Chemistry Guide 2024

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

Does Cloudy Pool Water Mean Algae? Expert 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

Does Covering Pool Prevent Algae? Complete Prevention Guide

I turned around at 2 AM to find my crystal-clear pool is now swamp green — desperately need to know if a cover will stop this algae disaster before tomorrow's party. The guys there keep pushing more and more expensive chemicals, and I swear they're just trying to upsell me on everything. Now they're telling me I need a pool cover to prevent algae, but I want to know if this actually works or if it's just another way to get money out of me.

I'm looking for honest advice here - does covering my pool genuinely prevent algae growth, or am I still going to need all those pricey chemicals even with a cover? I'd love to find some DIY solutions that actually work instead of constantly throwing money at this problem.…more

Can Pool Algae Kill You? Health Risks & Safety Guide

Turned on my pool lights last night and saw this green stuff floating around - total newbie here and honestly have no idea if this algae thing is dangerous. My pool has been fighting a losing battle against algae for weeks now, and it's gotten to the point where I'm genuinely worried about safety. The water is this nasty green mess, and I keep reading conflicting information online about whether algae can actually make you sick or worse.

I've got kids who are dying to swim, but I'm scared to let them anywhere near this swamp I used to call a pool. Is algae itself actually dangerous, or am I being overly paranoid? I know it makes everything slippery as hell, but are there real health risks I should be worried about? Just need to know if this is a "keep throwing chemicals at it" problem or a "nobody goes near the water" emergency.…more

Do Pool Covers Cause Algae? Prevention & Solutions Guide

Last month I moved into a house and discovered the previous owner's pool cover routine left me with constant algae blooms despite maintaining proper chlorine levels. I've been dumping shock and algaecide like crazy, but it keeps happening whenever I cover the pool.

Is the cover actually causing this algae growth? I thought covers were supposed to help keep pools clean, but mine seems to be doing the opposite. What am I missing here? There has to be a way to use a cover without turning my pool into a green swamp every week.…more
