Pool FAQs
Why does my pool keep getting cloudy?
It’s either too much junk in the water or not enough love. Check your filter, shock the pool, and test your chemicals. It’s not ghosts. Probably.
How often should I test my pool water?
Ideally twice a week. Or whenever you look at the pool and go, “Hmm… something’s off.” If your kids come out smelling like a bleach factory, that’s too late.
What should I do if algae shows up?
Shock it. Brush it. Laugh at its defeat. Then keep your chlorine levels up so it doesn’t come back like a bad sequel.
Can I just use bleach instead of chlorine?
You can. But only if you’re okay with playing chemist and potentially ruining your liner. Stick to pool-grade chlorine unless you love chaos.
How often should I backwash my filter?
When the pressure gauge says so, or when your filter looks like it’s trying to inhale concrete. Once a week is a decent rhythm.
Do I really need to vacuum the pool if I have a skimmer?
Yes. That skimmer’s not picking up the sand, grit, and toddler snack crumbs at the bottom. Suck it up. Literally.
What’s the ideal chlorine level?
1 to 3 ppm. Less than that, and it’s a bacteria rave. More than that, and you’re swimming in eye bleach.
