Beginner's Guide
You just got a pool and everyone's throwing chemistry terms at you. Relax. Here's everything you actually need to know, explained like a friend would explain it.
Pool maintenance sounds complicated because the internet makes it complicated. In reality, it comes down to three things: circulation, chemistry, and cleaning. Get these right and you'll rarely have problems.
Run your pump 8 to 12 hours a day. Moving water stays clean. Stagnant water grows algae. This is the single most important thing you can do.
Test your water once a week and keep chlorine, pH, and alkalinity in range. That's it. You don't need a chemistry degree. You need a test kit and 5 minutes.
Skim the surface, brush the walls once a week, and vacuum as needed. Empty the skimmer basket regularly. A robotic cleaner is a worthwhile investment.
There are really only 5 numbers you need to care about. Here's what each one means in simple terms:
This is the active chlorine that kills germs and algae. Think of it as your pool's immune system. If it's low, bad things grow. If it's too high, it irritates skin and eyes.
This measures how acidic or basic your water is. Your eyes are about 7.5, so keeping the pool near that makes swimming comfortable. Low pH burns. High pH makes chlorine lazy.
Think of this as pH's bodyguard. It keeps pH from bouncing around every time it rains or someone cannonballs. Always adjust this before adjusting pH.
Soft water eats pool surfaces. Hard water leaves crusty white deposits. You want it in the middle. Check it monthly, not weekly.
Sunscreen for chlorine. Without it, the sun destroys your chlorine in a few hours. Check it monthly. Chlorine tablets slowly add CYA over time, so watch for it creeping up.
This takes about 15 to 30 minutes once you get the hang of it.
Test water (FC, pH, TA at minimum). Adjust chemicals if needed. Empty skimmer basket.
Quick visual check. Skim surface if needed. Make sure pump is running.
Brush walls and floor. Vacuum if needed. Clean the waterline. Check pump and filter pressure.
Test calcium hardness and CYA. Clean or backwash filter. Inspect equipment for leaks.
❌ Not testing often enough
Test at least once a week. Problems are cheap to fix early and expensive to fix late.
❌ Adding chemicals without testing first
Always test before adding anything. You can't fix what you haven't measured.
❌ Not running the pump long enough
8 hours minimum per day. 10 to 12 in summer. Dead water breeds algae.
❌ Shocking in the middle of the day
Shock at dusk. UV rays destroy chlorine fast, so shocking at midday wastes half of it.
❌ Ignoring pH because chlorine looks fine
High pH makes chlorine 80% less effective. Your chlorine reading is lying if your pH is off.
Test kit or test strips (Taylor K-2006 for accuracy, strips for convenience)
Liquid chlorine or chlorine tablets
Muriatic acid (you'll use this a lot for pH)
Baking soda or alkalinity increaser
Pool shock (calcium hypochlorite)
Telescoping pole with brush and net attachments
Skimmer net for surface debris
Cyanuric acid / stabilizer
Set up your pool profile once (takes 30 seconds), then just enter your test results each week. Pool Clarity tells you exactly what to add, how much, and in what order. Written in plain English, not pool-store jargon.
