Muriatic acid is one of the most useful pool chemicals you can keep on hand, but it is also one of the easiest to overdo. A small dose can bring high pH back into range. A careless dose can push the water too low, irritate swimmers, and start chewing through alkalinity faster than you meant to. The goal is not to make the pH number move dramatically. The goal is to make a controlled correction, circulate the water, and retest …

Your pool pump runs every day, but do you actually know how long it should be running? Most pool owners either over-run it (wasting electricity) or under-run it (setting themselves up for algae and cloudy water). Getting this right matters more than people think. The short answer: most residential pools need 8–12 hours per day during peak summer. But the right number for your pool depends on pool size, pump flow rate, and water temperature. Here’s how to figure it …
You walk out to check on your pool and it’s not the sparkling blue you left it. It’s green. Or worse — pea soup green with something floating in it. Before you grab the shock and dump everything in at once, take a breath. Fixing a green pool the right way means you’ll be swimming again in a few days. Doing it wrong means spending another week looking at murky water and wasting a lot of chemicals. Here’s exactly what …
If your pool plaster looks rough and white, or your metal equipment is developing a greenish tinge, calcium hardness is probably the culprit. It’s one of those chemistry parameters that gets ignored until something goes wrong — and by then you’re looking at expensive repairs. Calcium hardness measures the concentration of dissolved calcium in your pool water. Get it right and your water is balanced. Too low and the water turns “hungry,” eating away at surfaces and equipment. Too high …
Your pool filter is doing the hardest work in your backyard — quietly trapping debris, oils, dead algae, and contaminants every single hour your pump runs. But filters don’t clean themselves, and a clogged or dirty filter is one of the most common reasons pools go cloudy, lose circulation, or fight algae that just won’t quit. The good news: cleaning your filter isn’t complicated. You just need to know your filter type, what to look for, and how often to …
Learn how to shock a pool the right way: which type of pool shock to use, how much to add, step-by-step instructions, and what to do after shocking to restore clear water fast. …
If there’s one pool chemistry problem that confuses more people than almost any other, it’s alkalinity. Pool owners hear about it constantly — test your alkalinity, raise your alkalinity, balance your alkalinity — but few resources actually explain what it does and why it matters so much. After years of working with pool water chemistry, here’s my honest take on total alkalinity and how to get it right. What Is Total Alkalinity, and Why Does It Matter? Total alkalinity (TA) …
Stop losing chlorine to summer sun. Learn the right CYA levels for your pool, how to test stabilizer, how to add it correctly, and what to do when CYA gets too high. …
# High pH and Low Chlorine: Why Your Pool Gets Cloudy Even When You Add Sanitizer High pH and low chlorine are a bad combination for pool water. Low chlorine gives algae and bacteria room to grow. High pH makes the chlorine you do have less effective. Put them together and a pool can turn dull, cloudy, or green even after you added sanitizer. This is one of the most common summer pool problems because pH tends to rise from …
# Pool Circulation Problems: How to Find Dead Spots Before Algae Starts Pool circulation problems usually show up quietly. One corner gets dusty. Steps feel a little slick. A ladder area turns green before the rest of the pool. The water may test fine near the surface, but algae still starts in the same stubborn place. That is a dead spot problem. Good circulation moves sanitizer, heat, and filtered water through the whole pool. Poor circulation leaves pockets where chlorine …
