Fiberglass Pool Winter Water Level: How Much to Leave In
Closing a fiberglass pool for winter isn’t as simple as draining it down and throwing on a cover. Leave too much water and your skimmer cracks; leave too little and the shell can shift or pop. Here’s exactly where the water level should sit and why it matters.

12×24 Above-Ground Pool Gallons: What It Really Means for Chemical Dosing
A 12×24 above-ground pool holds between 5,000 and 7,200 gallons depending on wall height. That number is the starting point for every chemical dose you add all season. This post walks through the math, then shows you exactly how much chlorine, shock, and pH adjuster to use.

Trichlor vs Cal-Hypo Shock for Closing a 20,000-Gallon Inground Pool
Choosing between trichlor and cal-hypo shock at pool closing time is more than a brand preference – the dose and timing differ for each. This post gives exact amounts for a 20,000-gallon inground pool and explains which type makes more sense for a winter shutdown.

How Much Antifreeze Does a Pool With a Heater and Two Skimmers Need?
Figuring out how much antifreeze a pool with a heater and two skimmers needs is trickier than the basic one-quart-per-line rule suggests. The heater adds extra plumbing volume, and two skimmers mean two separate lines to protect. This post walks through the math with real numbers so you buy exactly what you need.

Inground Pool Antifreeze With a Heater Bypass Line: How Much You Need
A heater bypass line adds real pipe volume that most antifreeze guides completely ignore. This post walks through exactly how to calculate how much antifreeze your inground pool needs when a bypass is part of the plumbing loop, with worked examples by pipe size.

12×24 Inground Pool Gallons: What the Number Means for Chemical Dosing
A 12×24 inground pool holds roughly 10,800 to 14,400 gallons depending on depth – and that number drives every chemical dose you add. Get the volume wrong and you’re either under-treating or wasting product. This guide walks through how to calculate your exact gallonage and what it means for chlorine, shock, alkalinity, and stabilizer.

Pool Replastering With a Fiberglass Step Insert: What It Costs
Replastering a pool that has a fiberglass step insert costs more than a plain shell, but the exact number depends on step condition, finish choice, and whether the steps need to be replaced entirely. This guide breaks down every cost layer so you know what to expect before the contractor shows up.

Above-Ground Pool Antifreeze With a Heater in the Plumbing Loop: How Much You Need
Winterizing an above-ground pool with a heater adds extra pipe footage to your antifreeze calculation, and most guides ignore that completely. This post walks through exactly how much non-toxic pool antifreeze you need, line by line, including the heater loop. You’ll leave nothing to freeze.

Pool Antifreeze for Skimmer Lines vs. Return Lines: How Much You Need
Skimmer lines and return lines hold different volumes of water, so they need different amounts of antifreeze. This guide walks through how to calculate exactly how many quarts to pour into each type of line based on pipe diameter and linear footage, so nothing freezes and cracks over winter.

Shocked Your Pool and It’s Still Murky? Do This Now
Let me guess. You finally got around to shocking your pool. Maybe it was after a weekend party, a storm, or just a moment of clarity where you remembered your water looked like it came from a swamp. You threw in some shock, probably patted yourself on the back, and expected the pool to reward…

The Curious Case of the Cloudy Pool That Wouldn’t Clear
It was a quiet Thursday morning when the call came in. The client said they had shocked their pool the night before. A textbook move, done right after a long weekend of sunblock, sweaty cannonballs, and maybe a spilled drink or two. But now the water looked like cold broth. Suspicious. Very suspicious. My job…

Your Pool Smells Like a Swamp? Here’s How to Fix It
You waited all winter for this moment. You peeled off the cover with a sense of anticipation, maybe even pride.

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.
